26138 Bacteria PCR & Sequence (BRBPS)

Bacteria PCR & Sequence (BRBPS)
Test Code: BRBPSSO
Synonyms/Keywords
Ribosomal RNA, Broad range, 16S, Bacterial Sequencing , PCR
Useful For
This test is used for detection and identification of bacteria (including mycobacteria) in normally sterile specimens after routine culture fails to exhibit growth.
Specimen Requirements
Specimen Type Preferred Container/Tube Acceptable Container/Tube Specimen Volume Specimen Minimum Volume
(allows for 1 repeat)		 Pediatric Minimum Volume
(no repeat)
​Tissue, fresh (bone, lymph node, heart valve, brain, viscera, organ, lung)   ​Sterile container ​ ​5 mm (3) ​5 mm (3) ​5 mm (3)
​Tissue Block ​Paraffin-embedded ​ 2 - 10 micro sections ​2 - 10 micro sections ​
​Fluid (CSF, vitreous, pleural, abdominal, peritoneal, ascites, pericardial, pelvic) ​Sterile container ​ ​1 mL ​0.5 mL ​0.5 mL
​Synovial Fluid ​EDTA Lavender Top Tube (LTT) ​ ​1 mL ​0.5 mL ​0.5 mL
Collection Processing Instructions

Test Information
This test was developed and its performance characteristics determined by Mayo Clinic in a manner consistent with CLIA requirements. This test has not been cleared or approved by the U.S. Food and Drug Administration.
Reference Range Information
Performing Location Reference Range
​Mayo Clinic Laboratories ​No Bacterial DNA Detected
Interpretation
A positive broad-range PCR/sequencing result indicates that bacterial nucleic acid of the specified organisms was detected, which may be due to bacterial infection or environmental or contaminating nucleic acids in the specimen. A negative broad-range PCR/sequencing result indicates the absence of detectable bacterial (including mycobacterial) nucleic acids in the specimen, but does not rule-out false-negative results that may occur due to sampling error, sequence variability underlying the primers, the presence of bacterial nucleic acids in quantities less than the limit of detection of the assay, or inhibition of PCR. If PCR testing appears to be negative but there is evidence of PCR inhibition, testing will be repeated. If inhibition is again detected, the result will be reported as "PCR inhibition present." This test was developed and its performance characteristics determined by Mayo Clinic in a manner consistent with CLIA requirements. This test has not been cleared or approved by the U.S. Food and Drug Administration.
