Preliminary Communication: Familial Accumulation of Carriers of Au Antigen

Abstract
The sibs and parents of 83 Au-positive blood donors were tested in order to study the possible family clustering of Au positives in a population with a low frequency of carriers of Australia (Au) antigen. Tested by counterelectrophoresis the incidence of Au antigen in the parents of Au-positive persons is 5·4% and in the sibs 17·9%, compared to 0·15% in blood donors.
