A recently transfused patient develop an antibody (e.g. Kidd) with MF autocontrol, does the work-up usually include delayed transfusion reaction work-up? How about a recently transfused patient who develop WAA, does the work-up include only differential allo-adsorption, DAT, Elution when DAT IgG +,Chloroquine and EGA treatment phenotyping when the DAT IgG + or am I missing something more? Dosage is not affected with antibody having low titer, isn't it? But rather dosage is affected by the number of antigen sites right? So is the statement false that goes "Low titer of antibody results in weak reactions appearing not to react with cells having heterozygoes expression of the antigen. Thanks
