Blood Center Adopts Faster Serum Hepatitis Test
In a few weeks, a faster, more sensitive screening test for the presence of the serum hepatitis antigen (Australia or SH antigen) in donated blood will go into routine use at the New York Blood Center.
It will detect at least 50% and perhaps up to 90% of carriers of the antigen, predicts Alfred M. Prince, MD, pathologist at the center. The currently used Ouchterlony agar gel diffusion technique detects only 25% to 30% of carriers (JAMAMEDICAL NEWS211:907 [Feb 9] 1970.)
The test, which is high voltage immunoelectroosmophoresis (IEOP), will detect "ten times less antigen and three times more carriers than the Ouchterlony technique," Dr. Prince told the seventh Gustav Stern Symposium on Perspectives in Virology meeting in New York.
The time required for the test is one to two hours, making it as fast as routine grouping and
