Variation in complement fixation test results with three Histoplasma capsulatum yeast phase antigens.

摘要

Antigens derived from three different yeast strains of Histoplasma capsulatum (GW and VC used by the Veterans Administration Serology Reference Laboratory and the Centers for Disease Control reference antigen, A811) were compared with each other to determine their equivalency. Results from 200 sera, tested concurrently by the Serology Reference Laboratory and the University of Kentucky Mycoserology Laboratory, indicated that the VC yeast antigen gave better correlation to the A811 antigen than did the GW antigen.
