HelpTest ID NBLD0404 Pneumocystis jiroveci, Molecular Detection, PCR, Varies
Reporting Name
Pneumocystis PCRUseful For
Preferred test for detection of Pneumocystis
Performing Laboratory
Mayo Clinic Laboratories in Rochester
Specimen Type
VariesAdditional 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 older than 7 days will be rejected.
Necessary Information
Specimen source is required.
Specimen Required
The high sensitivity of amplification by polymerase chain reaction requires the specimen to be processed in an environment in which contamination of the specimen by Pneumocystis species DNA is unlikely.
Preferred Specimens: Pleural, respiratory (eg, bronchoalveolar lavage [BAL], bronchial washing, sputum), or fresh tissue
Acceptable Specimens: If no fresh specimen is available, digested respiratory specimens treated with N-acetyl-L-cysteine-sodium hydroxide (NALC/NaOH) are acceptable (eg, BAL, bronchial washing, respiratory fluid, sputum, or tracheal secretion)
Submit only 1 of the following specimens:
