Abstract
BACKGROUND AND OBJECTIVES: IgA deficient patients are at risk of severe anaphylactic reaction on being transfused blood and blood products, and its prevalence varies in different parts of the world. No data are available from India.We did a blood donor survey to look for prevalence of IgA deficiency in north India.
METHODS: A sensitive enzyme linked immunosorbent assay developed in-house was used to detect IgA deficiency in a total of 3818 blood donors. Complete IgA deficiency was defined as value less than 5 mg/dl whereas partial IgA deficiency was defined as value between 5-30 mg/dl.
RESULTS: Of the 3818 blood donors screened, 3640 (95.3%) were males with a mean age of 31.2 yr. No donor was found to have complete IgA deficiency; however, 257 (6.7%) had partial IgA deficiency. INTERPRETATION AND CONCLUSION: Our study shows that IgA deficiency is rare in north India.
