**'''Antigen detection:''' Enzyme immunoassay (EIA) is typically performed on urine and/or serum, but can also be used on cerebrospinal fluid or bronchoalveolar lavage fluid. Sensitivity is generally higher in urine than in serum, particularly for HIV-infected persons with disseminated histoplasmosis.

Overview

There are no specific laboratory findings associated with acute histoplasma infection. Diagnosis is confirmed by the demonstration of the yeast cells from tissue samples or body fluids, culture and antigen detection.

Laboratory Findings

There are no specific laboratory findings associated with acute histoplasma infection. Diagnosis is confirmed by the demonstration of the yeast cells from tissue samples or body fluids, culture and antigen detection.

  • The following laboratory findings can be present in patient with a disseminated histoplasma infection:
    • Anemia
    • Leukopenia
    • Thrombocytopenia
    • Elevated liver enzymes
    • Elevated bilirubin
    • Elevated lactate dehydrogenase
    • Elevated ferritin
