Influence of ABO blood group antigen on activated partial thromboplastin and prothrombin time tests in healthy university students kosti city, White Nile state, Sudan

Abstract

Background: Variances in blood group antigen have been related with susceptibility particular to diseases. Prothrombin time [PT], measures the efficiency of the extrinsic and common coagulation pathways, although Activated partial Thromboplastin time [APTT] test evaluates the intrinsic and common coagulation pathways. Objective: To explore the influence of blood groups antigen on APTT and PT among Healthy University Students on different ABO blood groups. Materials and methods: Cross section study including student during the period of three months from September 2020 to December 2020 at Medical campus, University of El Imam El Mahdi, White Nile State, Kosti City, total of 480 students were enrolled. Four milliliters of venous blood was collected from each student, ABO blood grouping was done by the tile method whereas APTT, and PT were analyzed using the manual methods. Data were processed using the Statistical Package for the Social Sciences (SPSS) program version 26 by means of descriptive and inferential statistics. Results: Blood group O was largest among the test individuals [45%], followed by blood group A [30%] and B [16%], while blood group AB has the smallest percentage of (9%). Blood group O is significantly higher APTT value [39.07 ± 4.81] second compared to blood groups A [36.60 ± 5.89] second, AB [35.23 ± 4.86] second, and B [34.39 ± 5.30] second, P value < 0.05. Likewise, blood group A showed a significantly higher PT value [15.94 ± 1.36] second compared to blood groups O [14.12 ± 1.43] second, B [13.54 ± 1.35] second, and AB [14.67 ± 1.80] second, P < 0.05. Male had a higher APTT level (44.44± 7.27] second, PT [15.66 ± 1.88] second, and, compared with the female APTT [35.14 ± 6.49] second, PT [14.08 ± 1.29] second, P value < 0.05. Conclusion: Males have a higher APTT and PT levels compared to females. Blood group [O] individuals having a significantly higher APTT, while blood group [A]individuals having higher PT. This proposal that blood group of individuals may be affect their intrinsic (APTT) and extrinsic Coagulation mechanisms (PT].
