Test Code BRBPS Broad Range Bacterial PCR and Sequencing, Varies


Necessary Information


Specimen source is required.



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

Sources: Normally sterile tissue such as bone, lymph node, joint, heart valve, brain, viscera, organ, lung, prostate

Container/Tube: Sterile container

Specimen Volume: Entire collection or 5 mm(3)-approximately the size of a pencil eraser

Collection Instructions:

1. Collect fresh tissue specimen.

2. Submit tissue only, do not add fluid to tissue.

3. Freeze specimen.

Specimen Stability Information: Frozen <21 days (preferred)/Refrigerated <21 days

 

Alternate Specimen Type:

Preferred: Paraffin-embedded tissue block:

Supplies: Tissue Block Container (T553)

Specimen Type: Formalin-fixed, paraffin-embedded (FFPE) tissue block

Sources: Normally sterile or deep tissues such as bone, lymph node, joint, heart valve, brain, viscera, organ, lung, prostate

Container/Tube: Tissue block

Collection Instructions: Submit a formalin-fixed, paraffin-embedded tissue block to be cut and returned.

Specimen Stability Information: Ambient (preferred)/Refrigerated

 

Acceptable: Paraffin-embedded tissue block:

Specimen Type: Section (scrolls) of FFPE tissue block

Sources: Normally sterile or deep tissues such as bone, lymph node, joint, heart valve, brain, viscera, organ, lung, prostate

Container/Tube: Sterile container for each individual cut section (scroll)

Collection Instructions: Perform microtomy and prepare five separate 10-micron sections. Each section (scroll) must be placed in a separate sterile container for submission.

Specimen Stability Information: Ambient (preferred)/Refrigerated

 

Specimen Type: Fluid

Sources: Normally sterile body fluids such as cerebrospinal, vitreous humor, pleural, abdominal, peritoneal, ascites, pericardial, pelvic, prostatic

Container/Tube: Screw-capped, sterile container

Specimen Volume: 1 mL

Collection Instructions:

1. Collect fresh fluid specimen.

2. Freeze specimen.

Specimen Stability Information: Frozen <21 days(preferred)/Refrigerated <21 days

 

Specimen Type: Synovial fluid

Container/Tube:

Preferred: Red top or sterile container

Acceptable: Lavender top (EDTA), pink top (EDTA), royal blue top (EDTA), or sterile vial containing EDTA-derived aliquot

Specimen Volume: 1 mL

Collection Instructions: Send specimen in original tube (preferred).

Specimen Stability Information: Frozen <21 days (preferred)/ Refrigerated <21 days


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.

Reflex Tests

Test ID Reporting Name Available Separately Always Performed
ISBA Bacterial Ident by Sequencing No, (Bill Only) No
ISNGS Ident by Next Generation Sequencing No, (Bill Only) No
SPID2 Specimen Identification by PCR No, (Bill Only) No
CSFME Meningitis Encephalitis Panel, PCR Yes No

Testing Algorithm

If polymerase chain reaction (PCR) testing is negative, no sequencing is performed, and the test is 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).

 

The following algorithms are available:

-Infective Endocarditis: Diagnostic Testing for Identification of Microbiological Etiology

-Meningitis/Encephalitis Panel Algorithm
