Frequency of anti-HBV, CMV, and HTLV antibodies in donors at risk]

From July 1983 to January 1984 (7 months) information on AIDS and high-risk groups was given to each blood donor. A total of 139 subjects out of 136 384 (1.02%) declared to belong to such groups. Their blood donations were reserved to research purpose. Anti-HBc antibody was present in 43 subjects (31 %) in a frequency 6 times superior to what observed in an unselected population. Anti-CMV antibody was detected in 73% of these subjects. Both anti-HBc and anti-CMV antibodies were detected in 28% and were not in 24%. Antibody anti-p24 HTLV was never observed. beta 2 microglobuline was in a normal level in 70 of the 71 tested samples (mean 1.3 mg/l).
