Diagnostic test for Histoplasma capsulatum exposure

A diagnostic test for *Histoplasma capsulatum* exposure is an in vivo or in vitro diagnostic procedure used to assess cell-mediated or humoral immunity to the dimorphic environmental fungus *Histoplasma capsulatum* While most exposures result in asymptomatic infection or a mild, self-limited flu-like illness, exposure testing—such as intradermal histoplasmin skin testing or serological surveillance—identifies prior immunologic sensitization rather than differentiating active from inactive infect...

Primary infection typically occurs through the respiratory system via inhalation of airborne microconidia found in soil enriched with bird or bat droppings, predominantly affecting the lungs and the reticuloendothelial system
