Histoplasma and Blastomyces by PCR
Also known as: HIBL PCR
Use
This test serves as an adjunct in the diagnosis of histoplasmosis and blastomycosis. It is not a substitute for culture and/or antigen testing. Histoplasmosis and blastomycosis are fungal infections that can cause serious disease, especially in immunocompromised individuals. Detecting the presence of Histoplasma capsulatum or Blastomyces species through PCR can aid in timely diagnosis and management of these infections.
Special Instructions
Not provided.
Limitations
A negative result does not rule out the presence of PCR inhibitors in the patient specimen or the presence of test-specific nucleic acid at concentrations below the level of detection. The test does not differentiate between Blastomyces dermatitidis and Blastomyces gilchristii. It was developed and its performance characteristics determined by ARUP Laboratories. The test has not been cleared or approved by the U.S. FDA but is performed in a CLIA-certified laboratory for clinical purposes.
