The first example of anti-Gy^a detected in Hong Kong

The incidence of anti-Gy^a is known to be extremely rare, and only a few examples have been reported in Japanese persons and in Caucasians. This case history reports the first example of ant?-Gy^a detected in a Chinese person. The propositus is an 83-year-old male patient whose anti-Gy^a was revealed because of incompatibility of all units of blood tested by a saline indirect antiglobulin test (SIAT). Although the antibody had a titer of 512 by SIAT, 10 units of Gy(a+) red cells were transfused without any adverse effect.
