histoplasmin

 [his″to-plaz´min]
a skin test antigen prepared from the fungus Histoplasma capsulatum. Because positive skin tests are common in endemic areas and indicate only previous exposure, not necessarily active disease, histoplasmin is not useful in diagnosis of histoplasmosis. It is used primarily in epidemiologic surveys and in testing for cutaneous anergy in diagnosis of immunodeficiency.

his·to·plas·min

(his'tō-plas'min),
An antigenic extract of Histoplasma capsulatum, used in immunologic tests for the diagnosis of histoplasmosis; also used in skin test surveys of populations to determine the geographic distribution of the fungus and to predict those who are endemic for histoplasmosis.
