Use

This test is used for the detection of Histoplasma capsulatum antibodies. It involves the use of complement fixation (CF) and immunodiffusion (ID) methods to help identify active infections with Histoplasma capsulatum, which is a fungus that can cause histoplasmosis. CF titers of ≥1:8 with positive ID results (M or H band) are suggestive of active infection, while CF titers of ≥1:32 are strongly suggestive of active infection. This test provides useful information for diagnosing and managing patients suspected of having acute or chronic histoplasmosis.
