日本人に初めて検出された抗Do^aの1例とDo(a+b-)の1家系

抄録

We recently came across anti-Do^a in a patients' serum who had been pregnant and transfused.
The anti-Do^a was best detected by the indirect antiglobulin test with enzeme-treated red cells.
Testing bloods from 120 donors, we found 20 Do(a+) samples (16.7%).
The phenotype Do(a+b-) had not yet been detected in Japanese population. Testing the above 20 Do(a+) donors with anti-Do^b, we found 2 Do(a+b-) donors (1.7%).
