Indian Donors Research Articles

Burden of hepatitis B in asymptomatic blood donor population of India: A systematic review & meta-analysis.

Background & objectives India has been classified as an intermediate Hepatitis B Virus (HBV) endemic country, and the transmission is believed to mostly occur horizontally. However, community-based data on HBV prevalence among blood donors in India are limited. The burden of Hepatitis B Virus (HBV) is unknown in the asymptomatic blood donor population. We therefore conducted a meta-analysis to assess the prevalence of the HBV among the blood donor population in India. Methods We searched different databases for research articles on the prevalence of HBV in the blood donor population from India. Following the PRISMA guidelines, forty articles published between January 2013 and October 20, 2023, were selected for meta-analysis after removing duplicates and conducting a two-level screening process. Review Manager Version 5.3 (Rev Man 5.4) was used for statistical meta-analysis. The study has been registered with PROSPERO (number CRD42023487616). Results Forty articles were selected out of the 527 published manuscripts for meta-analysis, and a total of 22,22,736 blood donations were studied. Of these, 24,151 individuals (1.11%) were identified either as chronically infected with HBV or living with HBV infection. A pooled prevalence of approximately 1.11 per cent with a 95% confidence interval (CI) of (0.011; 0.0112) (common effect model) or 95% CI of (0.0079; 0.0116) (random effects model) was estimated. The included studies exhibited a high level of heterogeneity, probably due to different diagnostic approaches followed in different studies. Interpretation & conclusions The burden of hepatitis is profound, impacting public health, economies, and societies in India. The outcome of this study would help address such a burden and develop comprehensive strategies focused on prevention, early diagnosis, treatment, and necessary collaboration to achieve significant reductions in hepatitis-related morbidity and mortality.

A cross-sectional pilot study to estimate the frequency of minor blood group alleles and phenotypes in RhD-negative North Indian blood donors by DNA microarray analysis

Abstract: INTRODUCTION: There are scarce data on Indian blood donors with respect to blood group phenotypes using molecular diagnostic modalities. Hence, we planned to estimate frequencies of blood group alleles/phenotypes using DNA microarray analysis in the north Indian RhD-negative blood donor population. With this initial pilot study, we plan to expand it to our entire donor population. METHODOLOGY: The cross-sectional prospective study was conducted on 50 Indian blood donors (O RhD negative), to study the blood group genotype frequency. Genotyping for the most relevant red blood cell antigens (Rh, Kell, Duffy, Kidd, MNS, Lutheran, and Dombrock) was done using Bioarray Precise TypeHM Human Erythrocyte Antigen BeadChip kit containing probes directed to polymorphic sites. RESULTS: In the Rh system, the most common alleles were RHCE*e/RHCE*e (98%) and RHCE*c/RHCE*c (80%). Phenotype K-k+ (genotype- KEL*02/KEL*02) was seen in 98% of samples, Js(a-b+) (KEL*02.07/KEL*02.07) was detected in 98% (49/50) of the samples tested. Jk(a + b+) (JK*01/JK*02) was the most common phenotype (48%) in the Kidd blood group system. In MNSs system, M+N+ (GYPA*01/GYPA*02) 44% and S+s+U+ (GYPB*03/GYPB*04) 34% were the most common phenotypes detected. CONCLUSION: This pilot study shows the feasibility of genotyping a Northern Indian donor population. To the best of our knowledge, it is the first study on molecular blood grouping in Indian blood donors using the Bioarray platform.

Biological Reference Ranges for Healthy Indian Blood Donors: Experience of a Tertiary Care Center Vis-à-Vis International Literature.

Complete blood count is the most common, basic test requisitioned in hematology. The normal reference ranges of hematological parameters are required owing to variable socioeconomic, environmental, and genetic factors in populations. The current study determines the reference ranges of the healthy Indian donor population of a high socioeconomic group. The study was conducted in the Department of Transfusion Medicine at a tertiary care hospital in India and included 4098 individuals, aged 18-65 years coming for voluntary blood donation from July 2021 to October 2022. Blood samples were collected in K2EDTA, analyzed on the Sysmex XN-31 hematology analyzer, and using statistical tools, the normal reference ranges were calculated. The reference ranges for hemoglobin (HB) (137-185 g/L), WBC (5.1-1.7 × 109/L), platelet count (115.6-370.0 × 109/L) were noted. No statistically significant changes were observed in different age groups. There were gender-wise differences noted in nearly all parameters. The HB and hematocrit (HCT) range was slightly higher in other Indian and other Asian populations with comparable values with the Chinese, Korean populations, and Western populations; RBC parameters were overall comparable with minor differences; the WBC count was higher than the other Indian and Asian populations particularly the upper limit of lymphocyte and monocyte; and the range of platelet counts had a comparable upper limit with all populations and had the lowest lower value in males in our study, which was comparable to only the Chinese population. It is concluded that reference ranges of common parameters were calculated with minor changes noted in all hematological parameters on comparing with other Indian, Asian population, and Western data.

THE DECISION-MAKING PROCESS OF RENAL DONORS: A QUALITATIVE STUDY FROM INDIA

The study explores the decision-making process of renal donors in India, aiming to understand the motivations, emotions, and contextual factors that influence their choices. Through in-depth interviews with a diverse group of kidney donors, the research delves into their personal experiences and the societal pressures that shape their decisions. The findings reveal that altruism, a sense of duty towards family or community, and personal health experiences significantly drive individuals to donate a kidney. Results: Researcher conducted semi-structured interviews with 20 donors the day before their scheduled donation. Data collection involved open-ended questionnaires, which were voice recorded and analysed using a grounded theory and interpretative approach. The findings indicated that the primary motivation for donation stemmed from the suffering of the recipient. Notably, many mothers chose to donate despite the presence of other potential living donors. All participants confirmed that their decision was made voluntarily, without any external pressure. Throughout the interviews, donors consistently expressed that the recipient's recovery was more important than their own health, a sentiment driven by deep emotional connections. Conclusion: The study found no evidence of coercion among donors, who exhibited a strong awareness of their choices and made voluntary decisions driven by emotional motivations. The primary factors influencing their decision to donate were emotional attachments and concerns for the recipient’s well-being, highlighting the profound impact of personal connections in the organ donation process.

Increased parvovirus B19 seropositivity in healthy blood donors in India

A core component of every blood program is the supply of safe blood and blood products. The elevated risk of transmission through these products is due to parvovirus B19 (B19V) resistance to the virus inactivation procedures. Our study aimed to screen asymptomatic blood donors for B19V at a tertiary care hospital in Chennai, Tamil Nadu, between September 2020 and June 2021. Sera from 106 healthy blood donors who tested negative for Human immunodeficiency virus (HIV), Hepatitis B surface antigen (HBsAg), Hepatitis C virus (HCV), syphilis, and malaria were tested for anti-B19V IgM and IgG using a qualitative indirect enzyme-linked immunosorbent assay (ELISA). In the study population, 23.5% (n = 25) of donors tested IgM positive, 38.6% (n = 41) tested IgG positive, and 7.5% (n = 8) tested positive for both IgM and IgG. A proportion of 61.3% (n = 65) of the blood donors tested IgG negative, suggesting they had no past B19V infection. B19V DNA was not detected in any of the subjects. The high seroprevalence of IgM indicates that blood donors may have been recently exposed to B19V, potentially posing a risk to immunocompromised individuals and those with hematological stress. Further longitudinal studies with a larger sample size are recommended to better understand the risk of B19V transfusion transmission.

A study on comparison of Tc-99m DTPA renal dynamic imaging with Mayo quadratic, Cockcroft-Gault, MDRD, and CKD-EPI formulas for estimation of glomerular filtration rate among South Indian live-related kidney donors

Introduction: Glomerular filtration rate (GFR) is calculated using various prediction equations. These equations are derived from the Western population, and extrapolating to our population subgroups may yield inaccurate results. Objectives: To study the correlation of measured GFR to estimated GFR using four different equations and to analyse how much proximity lies between the GFR calculated by above formulas correlates with DTPA renal scan among South Indian renal donors. Patients and Methods: An observational study was conducted among prospective renal donors undergoing evaluation. Donors underwent a DTPA scan as per protocol. Downloadable calculators calculated the glomerular filtration rate. Results that were descriptive were presented as mean and standard deviation. Correlation and comparisons were made by calculating Pearson’s correlation coefficient and student’s t test respectively. Results: A total of 151 patients were included; 24.5% were males and 75.5% were females. The majority of donors (37.09%) were in the 45-54 years age group. The mean of measured GFR by DTPA was 105.64 mL/min/1.73 m2 whereas estimated GFR was 100.95, 102.34, 109.35, 97.44 mL/min/1.73 m2 in MDRD, CKD-EPI, Mayo, and Cockcroft Gault (CG) formulae respectively with a maximum mean difference for CG of 8.2. Weighted kappa agreement between measured and estimated GFR shows 82.96% agreement with CKD-EPI compared to 78.09% agreement with the MDRD formula. Overall, CKD-EPI performed better in GFR estimation in our study subjects. Conclusion: We found that the CKD-EPI formula performed better in precision, correlation, and accuracy compared to other formulae in GFR estimation among healthy South Indian renal donors. Therefore, the CKD-EPI formula is best suited to pick-up subnormal GFR in clinical practice, as well as in epidemiological studies among the South Asian population.

Comparison of Different Equations with GFR Measured by Scintigraphy in Kidney Donors.

Technetium-99m diethylene-triamine-pentaacetate (99mTc-DTPA)-based scintigraphy is a convenient way to assess measured glomerular filtration rate (mGFR) in kidney donors. Equations have been developed to calculate GFR in the general population. This study aims to identify the best among commonly employed equations to better predict GFR when compared with scintigraphy-based mGFR. Also, the trends in mGFR values were studied over 1 year post-donation. Thirty-four kidney donors were recruited for this study from November 2017 to November 2018 and followed-up for a year. Estimated GFR (eGFR) was calculated using the Modification of Diet in Renal Disease (MDRD) Equation, Chronic Kidney Disease Epidemiology (CKD-EPI) Collaboration equation, and Nankivell formula; the values were compared to that obtained using 99mTc-DTPA both pre-and post-donation. Correlation and agreement between the eGFR and mGFR were studied using Statistical Package for the Social Sciences (SPSS) version 23.0 and Microsoft Excel. mGFR was augmented by 32.3 ± 27.8% in the remnant kidney post-donation. The baseline mGFR, post-donation mGFR, and the quantum of its increase post-donation did not differ between overweight donors and donors with normal body mass index (BMI). mGFR correlated poorly with all the eGFR equations both pre- and post-donation. Bland-Altman analysis showed weak agreement with significant bias and variance between mGFR and all eGFR equations. In Indian kidney donors, mGFR by 99mTc-DTPA scintigraphy shows poor correlation and agreement with the commonly used eGFR equations. An individualized approach is needed to assess the kidney function of live donors to minimize harm to both the recipient and the donor.

Retrospective study to compare the outcomes of matched related donor vs matched unrelated donor in patient with acute myeloid leukaemia

BackgroundIndia's need for bone marrow donation and transplantation is increasing in the context of the rising incidence of haematological neoplasms like acute myeloid leukaemia (AML). The use of matched related donors (MRD) for hematopoietic stem cell transplantation (HSCT) is a feasible option, but the lack of HLA-matched donors in India remains a significant obstacle to successful treatment. MethodologyThis retrospective study was conducted at the Department of Hemato-Oncology & Bone Marrow Transplant, Rajiv Gandhi Cancer Institute in New Delhi, India over a period of 6 months. The study enrolled 77 AML MRD and 19 AML MUD patients based on the inclusion and exclusion criteria. ResultThe one-year survival rate was higher in MRD than in MUD, but there was no significant difference in mortality in multivariate analysis. The study also found that chronic graft-versus-host disease (GVHD) and relapse were associated with worse survival outcomes in both MRD and MUD HSCT. ConclusionThis study supports the use of matched unrelated donor (MUD) transplant for HSCT in AML patients when a matched sibling donor is not available.

Volunteer and NGO Matching Platform

According to a poll conducted in 2021, during the epidemic, the number of donors in India increased by 43%. During the pandemic, Indian non-governmental organizations (NGOs) volunteered their services in every manner conceivable, and they still do. However, over the years, the proportion of volunteers has remained consistent. This demonstrates a disconnect between the general population and nonprofits as well as volunteerism. Establishing a platform that connects these volunteers with other charitable organizations would be crucial. The "Volunteer Matching Platform" project may be able to bridge this gap. This web-based platform is intended to facilitate volunteer connections between non-governmental organizations and local groups. NGOs will use this platform to promote their events to the nation's citizens. On the other hand, volunteers will be able to browse through the available opportunities, filtering based on their interests, location, and availability.

Blood Group Discrepancy in a Donor Due to a Rare Ax/Aweak Subgroup Phenotype with ABO*AW.31.01/*O.01.75 Genotype

ABSTRACT The most crucial blood group system in transfusion medicine is still the ABO system. Any unresolved discrepancy could result in the patient receiving blood that is incompatible and could trigger acute intravascular hemolysis. ABO subgroups are one of the astounding differences in blood grouping. The amount of A and B antigens carried by red blood cells and present in secretion varies depending on the ABO subgroup phenotype. Clinically, A1 and A2 are the two most frequently observed subtypes. Many weaker A subgroups have been described, including A3, Axe, am, and el. This example involves an Indian male donor who was initially misclassified as a Group O individual before being identified as an Ax/Aweak subgroup phenotypically. The next-generation sequencing defined the genotype of this case as ABO*AW.31.01/*O.01.75.

Clinically significant minor blood group antigens amongst South Indian donor population

Background and objectives: Distribution of blood group antigen varies among different races. It is important to know the distribution of these antigens so as to provide a donor database that aid in providing compatible blood units for patients with multiple alloantibodies. The present study was conducted to determine the distribution of clinically significant minor blood group antigens amongst the South Indian blood donors. Materials and methods: Blood samples were collected from healthy regular repeat voluntary blood donors of same ethnicity attending a tertiary care hospital in South Kerala. Clinically significant blood antigens of the ABO, Rh (D, C, c, E, and e), Kell, Duffy and Kidd blood group systems were determined. The ABO and Rh(D) grouping were performed by tube technique using monoclonal antisera. Column agglutination technique was used to phenotype Rh, Kell, Duffy and Kidd antigens. Results: Total 200 healthy repeat voluntary blood donors were enrolled in the study. Out of 200 donors, 92% were RhD positive. Among the Rh antigens, the e antigen was positive in 97.8 % and 100% among the Rh(D) positive and Rh(D) negative donors respectively. No E antigen was detected in RhD negative donors. Total 6 and 2 Rh phenotypes were observed among the Rh(D) positive and negative donors respectively. R1R1 and Rr were the most frequent phenotypes among the RhD positive and negative donors (47.28% and 93.75%) respectively. Among the Kell blood group antigens, K and Kpb antigens were present in 100% of our donors while in Duffy and Kidd system Fya and Jka were most predominant (89% and 87%) respectively. Conclusions: The findings of the present study would be helpful in developing in-house panel cells. Moreover, a rare donor registry of donors typed negative for a high-frequency antigen can be formulated. IMC J Med Sci. 2024; 18(1):004.

Generation of control human iPSC line INSTEMi001-A from PBMCs of a healthy Indian donor

Human pluripotent stem cells serve as a robust model system to study disease pathogenesis in a dish and search for various targeted therapeutics. Collection of control lines from healthy individuals are essential for any study. Therefore, we have generated hiPSC line from a healthy male donor after episomal reprogramming of PBMCs. The generated line is pluripotent, had normal karyotype and has a potential of tri-lineage differentiation. The generated line would serve as control line of Asian origin from Indian population.

Organ Donation Management System (Project: ODMS)

Organ Donation Management System is a novel idea to support organ donors in India with a new age interface and ease of registration, and systematic guidelines of Government India to ensure the legalities. As we included a Aadhar authentication for this process to register a donor, we duly abide by the laws, values and of Donors to serve the communities in India. ODMS is an online system which consists of Android Application and a Website. The health care system has access to detailed information of patients and donors within a management. As the penetration of Mobile phone and gadgets is another boon for this project idea deployment. We designed a system if a user willing to donate organs post their death due to an unfortunate accident or incident with help of Aadhar system we trace the organ donor and within the golden period we take the permission of family members of deceased organ donor to transplant his organs to other patients in need. Aadhar plays a pivotal role in this entire process for Authentication, Tracking the deceased donors and the Know Your Donor called as KYD where a donor himself provide a legal acceptance of organ donation post his death through video KYC and digital forms filling.

GVHD relapse-free survival after peripheral blood hematopoietic cell transplantation for hematologic malignancies.

The preferred choice for hematopoietic cell transplantation (HCT) donors in India is a matched related donor (MRD) followed by a haploidentical (haplo) donor for patients with hematological malignancies. International data in the haplo-HCT setting is mainly using bone marrow as a source. Almost all HCTs in India use peripheral blood stem cells (PBSC), which increases the risk of graft-versus-host disease (GVHD). In this single-center prospective study from 2017 to 2021, we sought to compare these outcomes prospectively in adult patients with hematological malignancies. Patient, disease, donor, and HCT details were prospectively recorded. GVHD prophylaxis included cyclosporine + methotrexate in MRD-HCT and post-transplant cyclophosphamide (PTCy) based in haplo-HCT. The primary endpoint GVHD relapse-free survival (GRFS) was defined as the time post-HCT without any of the following events: grade III-IV acute GVHD, chronic GVHD requiring systemic immunosuppressive treatment, disease relapse, or death from any cause. A total of 41 MRD and 33 haplo-HCT recipients were included in the study. Both cohorts were matched for age, sex, diagnosis, disease risk index, donor age, sex and CMV mismatches, and CD34 counts. A lower proportion of MRD-HCT recipients than haplo-HCT received myeloablative conditioning (39% vs. 76%, p = 0.002). There was no difference in the cumulative incidence of grade III-IV acute GVHD (16% vs. 27%, p = 0.2) or moderate-to-severe chronic GVHD (58% vs. 71%, p = 0.5). The one-year GRFS was not significantly different (53% vs. 38%, p = 0.2), with median GRFS of 420 and 274 days. The relapse incidence (22% vs. 19%, p = 0.6) and non-relapse mortality (25% vs. 35%, p = 0.4) did not differ. There was no difference in overall survival at one year (60% vs. 52%, p = 0.3). Despite a higher proportion of myeloablative conditioning in the haplo-HCT cohort, all outcomes, including GRFS, were comparable to those of the MRD-HCT cohort. This should encourage patients without an MRD to undergo haplo-HCT.

Peri-hilar branching pattern and variations of the renal artery among Indian kidney donors using pre-operative computed tomography angiography: an anatomical study and review.

The peri-hilar branching pattern of renal arteries and variations such as accessory renal artery and early branching of the renal artery are important factors to be evaluated preoperatively to minimise potential complications during renal transplantation and renal surgeries. The present study was done to assess the peri hilar branching pattern of the renal artery and its variation among the renal donors in India. One hundred ninety eight kidneys from 99 donors were analysed using pre-operative computed tomography renal angiograms prospectively, over 1 year 2 months. Based on the branching pattern of primary and secondary branches of renal arteries, we identified 8 cardinal and 10 minor peri-hilar branching patterns. Type I (duplicated fork) peri-hilar branching pattern was the most frequently found (70.2%) among 198 kidneys, followed by type II (triplicated fork) (19.2%) and type III (ladder) (10.6%). Duplicated fork pattern was common in both the right renal artery (75.7%) and left renal artery (64.6%), respectively. The prevalence of accessory renal artery was 39.4% with hilar artery at 21.2% and polar artery at 18.2%, and the prevalence of early division of renal artery was 20.2%. No significant association was found between gender and laterality in the prevalence of both early division and accessory renal artery (p > 0.05). Early division of renal artery was more frequent in females (28%) whilst accessory renal arteries were more common in males (40.7%). The present study showed a consistent peri-hilar branching pattern with high individual variability among Indian renal donors. The knowledge about the peri-hilar branching pattern as well as renal artery variations conferred by this study would greatly compliment urological surgeons during renal transplant surgeries.

Prevalance of serologic weak D in Rh D negative blood donors in India: Immunohematological problems & recommendations for donors

The Rhesus (Rh) system is one of the most complex blood group systems in humans. In some individuals Rh D antigen show weaker expression on red cells. The aim of the study was to find out the prevalence of serologic weak D in north India and associated immunohematological problems.Cell and serum grouping were performed on all sample with the help of Qwalys 2 & Qwalys 3 (Diagast, France). All Rh D negatives samples in routine blood grouping were subjected to serologic weak D testing with the help of Erythrocytes Magnetized (EM) Technology.Total 65,407 whole blood donors were tested for blood grouping in the study period. Prevalence of serologic weak D phenotype in this study was 1.11% of Rh negative donors. The maximum number of serologic weak D phenotype were from B blood group, i.e. 13 (37.14%). The prevalence of serologic weak D varies in different part of India as well as in the world. This study reported 1.11% prevalence of serologic weak D among Rh D negative blood donors. All serologic weak D positive individuals should give a blood group card showing their Rh D status as donor and recipient. Some European centers started routine RHD gene screening of first-time donors to eliminate the risk of Rh D sensitization. Molecular testing is very costly.For developing countries like India we required an affordable molecular testing technique to improve patient care or alternatively establish reference molecular laboratory for cost effectiveness.

Prevalence of Rh and K phenotypes among blood donors from different ethnicities in Samtah (Southwestern Region) Saudi Arabia.

Rh and Kell blood group systems are amongst the most important blood group systems; being highly immunogenic after ABO system. The aim of this study was to evaluate the frequencies of Rh antigens, haplotypes and K antigen among blood donors belonging to various ethnicities in Samtah, Jazan, Saudi Arabia. This study was conducted during January 2019 and August 2020 at Samtah General Hospital, Samtah. Records of all blood donors recruited during this period were included for data acquisition. A total of 4977 blood donors' records were reviewed and data were analysed. A total of 3863 donors' results were considered in the final analysis. In comparison to Saudi blood donors, C antigen was less frequent in Sudanese donors (69.7% and 34.0%), the c antigen was less frequent in Indian (79.2% and 59.3%) and Philippine (79.2% and 40.0%) donors and more frequent in Sudanese (79.2% and 97.9%) donors, the E antigen was less frequent in Yemini (27.0% and 19.5%) and the e antigen was more frequent in Yemini (96.7% and 99.2%) donors. The DcE haplotype was less frequent (3.1% and 0.7%) and the ce haplotype was more frequent (4.3% and 7.6%) in Yemini donors. The K antigen was less frequent in Pakistani (11.9% and 4.1%; p = .041) and Indian (11.9% and 1.9%; p = .023) donors. Rh and K antigens showed marked variations in their frequencies among blood donors of different ethnicities. Utilization of blood from various ethnicities warrant extended phenotyping of Rh and K antigens to avoid the risk of alloimmunization in multiply transfused patients.

A combination of potently neutralizing monoclonal antibodies isolated from an Indian convalescent donor protects against the SARS-CoV-2 Delta variant.

Although efficacious vaccines have significantly reduced the morbidity and mortality of COVID-19, there remains an unmet medical need for treatment options, which monoclonal antibodies (mAbs) can potentially fill. This unmet need is exacerbated by the emergence and spread of SARS-CoV-2 variants of concern (VOCs) that have shown some resistance to vaccine responses. Here we report the isolation of five neutralizing mAbs from an Indian convalescent donor, out of which two (THSC20.HVTR04 and THSC20.HVTR26) showed potent neutralization of SARS-CoV-2 VOCs at picomolar concentrations, including the Delta variant (B.1.617.2). One of these (THSC20.HVTR26) also retained activity against the Omicron variant. These two mAbs target non-overlapping epitopes on the receptor-binding domain (RBD) of the spike protein and prevent virus attachment to its host receptor, human angiotensin converting enzyme-2 (hACE2). Furthermore, the mAb cocktail demonstrated protection against the Delta variant at low antibody doses when passively administered in the K18 hACE2 transgenic mice model, highlighting their potential as a cocktail for prophylactic and therapeutic applications. Developing the capacity to rapidly discover and develop mAbs effective against highly transmissible pathogens like coronaviruses at a local level, especially in a low- and middle-income country (LMIC) such as India, will enable prompt responses to future pandemics as an important component of global pandemic preparedness.

Comparison of creatinine-based glomerular filtration rate estimation equations in voluntary Indian kidney donors: A single centre study

Introduction: In transplantation, accurate estimation of the donor glomerular filtration rate (GFR) is crucial. While various creatinine-based equations are in use, none are validated in Indians. Objectives: This study was conducted to judge the accuracy of creatinine-based GFR estimation equations and urinary creatinine clearance. Patients and Methods: A single-centre, observational and retrospective study at a tertiary care hospital. Adult voluntary donors GFR measured (mGFR) by technetium-99m diethylenetriaminepentaacetic acid (Tc-99m DTPA) were included. The primary outcome was the performance of estimated GFR (eGFR) by "Cockcroft-Gault’s formula corrected for body surface area (CG-BSA) formula", "modification of diet in renal disease (MDRD) 4 and 6 variable equation" and "Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation"; secondary outcome was the performance of "24-hour urinary creatinine clearance (Cr Cl)". Results: 102 kidney donors were analysed with mean age of 45.89 ± 9.98 years and 85.3% females. Mean ± SD mGFR by Tc-99m DTPA was 82.11 ± 14.32 mL/min/1.73 m2 . Mean ± SD eGFR by "CGBSA" was 99.68 ± 23.71 mL/min/1.73 m2 , by "MDRD-4 variable equation" was 98.25 ± 28.61 mL/ min/1.73 m2 , by "MDRD-6 variable equation" was 93.66 ± 19.44 ml/min/1.73 m2 and by "CKD-EPI" was 111.14 ± 31.61 mL/min/1.73 m2 . The lowest bias (2.3), highest precision (16.23), and accuracy (97.1%) were with "MDRD-6 variable equation"; "24-hour urinary Cr Cl" highly overestimated GFR (158.27 mL/min/1.73 m2 ) with the highest bias, lowest precision, and accuracy. Conclusion: The "MDRD-6 variable equation" was the most precise and accurate of the equations, whereas "24-hour urinary Cr Cl" was the least dependable. This study highlights the need for a correction factor or a new GFR estimation equation and not to consider urinary Cr Cl to assess donor GFR.
