The significance of hepatitis B antigenaemia in symptom-free blood donors in Kenya.

: One-hundred and eight blood donors found to have hepatitis B antigenaemia have been examined for evidence of liver disease. In five the liver was enlarged, and in six apparently normal donors there was histological evidence of disease. One or more tests of liver function were abnormal in an additional fifty-three donors without definite evidence of disease. Estimation of serum transaminases was the most reliable test and we recommmend that these be measured in all antigen-positive donors.
