Discrepancy in ABO Blood Grouping in a Blood Donor: A Case Report
Journal Title: Iranian Journal of Blood and Cancer - Year 2018, Vol 10, Issue 2
Abstract
Detection of ABO blood groups through agglutination is the basis of pre-transfusion testing. However, weak agglutination reactions may be obtained with reagent antibodies and are a result of weak expression of A and B antigens on red blood cell surface which may cause a discrepancy in blood group typing. Here, we report a donor which showed discrepancy between red blood cells (forward) and serum (reverse) typing. A detailed analysis revealed the blood type as a variant of blood group B. Subgroup of B is a very rare phenotype of blood. This is the first case ever detected in Kurdistan blood transfusion Center.
