Abstract

The aim of the present study was to know the prevalence of viral hepatitis markers among blood donors deferred on the basis of a history of jaundice of unknown origin and to predict the impact of this deferral on blood safety. Observational study included 200 blood donors deferred on the basis of a history of jaundice of unknown origin and carried out serology and Individual Donation Nucleic Acid Testing (ID-NAT) for hepatitis B and hepatitis C. Five (2.5%) out of 200 blood donors deferred on the basis of history of jaundice were reactive on ELISA. Three out of five were reactive for HBsAg; whereas two for anti-HCV antibodies. Out of the 12 ID-NAT initial reactive, 10 samples discriminated on further testing; 4 for HBV, 5 for HCV and 1 was co-infection (HBV+HCV). The odds of being picked up as sero reactive on ELISA was 2.53 (95% CI; 1.04-6.19) and being picked up as ID-NAT yield was 13.08 (95% CI; 5.29-32.37) in donors deferred on a history of jaundice of unknown origin as compared to selected donors without a history of jaundice, with the difference in means achieving statistically significance at P=0.03 and <0.001 respectively.The potential of deferral on a history of jaundice of unknown origin has a capacity to interdict 2-3 HBV and/or HCV reactive blood donors on serology and 5 HBV and/or HCV reactive blood donors on ID-NAT from entering the quarantine blood supply per 100 donors. The findings of the present study support that a deferral for a history of jaundice of unknown origin after attaining the age of 12 years in the present scenario of transfusion transmissible infectious disease screening in India.
