Frequency of IgA deficiency in blood donors and Rh negative women in Iceland. 1977

S Gudmundsson, and O Jensson

Sera from 6,842 individuals were tested for IgA deficiency, using double and radial immunodiffusion. Sera containing less than 1 mg/100 ml of IgA were classified as deficient. The frequency of selective IgA deficiency among 4,799 blood donors investigated was 1:533, but 1:340 among 1,017 Rh negative women screened and 1:485 for both groups combined. One of the nine IgA deficient blood donors detected belonged to a 1st cousin marriage family previously investigated, in which the mother also was deficient in IgA. One IgA deficient recipient was found among 704 hospital patients screened for this abnormality.
