HelpTest Code LAB93796 Broad Range Bacterial PCR and Sequencing, Varies
Additional Codes
BRBPS
Useful For
Detecting and identifying bacteria (including mycobacteria) from normally sterile sources, including synovial fluid; body fluids such as pleural, peritoneal, and pericardial fluids, cerebrospinal fluid; and both fresh and formalin-fixed paraffin-embedded tissues
This test is not recommended as a test of cure because nucleic acids may persist for long periods of time after successful treatment.

Testing Algorithm
If polymerase chain reaction (PCR) testing is negative, no sequencing is performed, and the test resulted as negative.
If PCR testing is positive, sequencing is performed. Strong positive results are first submitted to Sanger sequencing, which can yield results in as few as 4 days. Weak positive results, or Sanger sequencing results that are mixed, are submitted to next-generation sequencing (ie, targeted metagenomics testing).

Specimen Required
Fresh tissue is preferred over formalin-fixed, paraffin-embedded tissue.
Submit only 1 of the following specimens:
Preferred Specimen Type:
Specimen Type: Fresh tissue or biopsy
