Tests and diagnosis

By Mayo Clinic Staff

Diagnosing histoplasmosis can be complicated, depending on the area of the body affected. While testing is not usually necessary for mild cases of histoplasmosis, it can be crucial to help choose appropriate treatments in life-threatening cases.

Available tests for histoplasmosis have limitations. For example, it can take up to six weeks to get results from some tests. Your doctor may suggest a combination approach to search for evidence of the disease in samples of:

  • Lung secretions
  • Blood or urine
  • Biopsied lung tissue
  • Bone marrow

Researchers are working on developing better tools to diagnose histoplasmosis.
