Test ID: HBRP    
Histoplasma capsulatum/Blastomyces species, Molecular Detection, PCR, Varies

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

See Meningitis/Encephalitis Panel Algorithm in Special Instructions.

Specimen Type Describes the specimen type validated for testing

Varies

Advisory Information

Urine is not an acceptable source for this assay. Studies indicate that Histoplasma DNA is not routinely found in the urine of patients with disseminated histoplasmosis. Therefore, the UHIST / Histoplasma Antigen, Urine is the recommended test for this specimen source.

Additional Testing Requirements

This test should always be performed in conjunction with fungal culture, order FGEN / Fungal Culture, Routine.

Shipping Instructions

Specimen must arrive within 7 days of collection; specimens received after 7 days will be rejected.

 

NALC/NaOH-digested specimen must arrive within 7 days of digestion.

Necessary Information

Specimen source is required.

Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing

The high sensitivity of amplification by PCR requires the specimen to be processed in an environment in which contamination of the specimen by Histoplasma or Blastomyces species DNA is not likely.
