UCHealth Cherry Creek Medical Center Laboratory
Collect
ESwab® of throat, tonsillar area.
Avoid touching the tongue, cheeks, and teeth with the swab when collecting the specimen.
Unacceptable Conditions
Any source other than throat.
Any swab other than an eSwab®.
Sample not properly identified, incorrect container, insufficient volume, or past stability.
Storage/Transport Temperature
Internal: Ambient Offsite: Refrigerated
Performed
Daily
Stability (from collection to initiation)
Room Temp: 2 days Refrigerated: 6 days Frozen: Unacceptable
Remarks
This assay may be used instead of a Rapid Strep Antigen test or as confirmatory testing following a negative Rapid Strep Antigen result.
Performed
Daily
Methodology
Qualitative Real-time PCR using Cepheid® GeneXpert®
Reported
Same day
Synonyms
GROUP A STREP
GAS PCR
Strep Throat
Group A Streptococcus PCR
EPIC Code
LAB8664 GROUP A STREP
Reference Interval
Not detected
Interpretive Data
Interpretation:
Not detected = Absence of Group A Strep DNA
Detected = Presence of Group A Strep DNA
Methodology:
This assay employs real-time PCR amplification using Streptococcuspyogenes specific primers and probes. A "Detected" result should be coupled with clinical indicators for diagnosis. A "Not detected" result for this assay does not exclude Group A Strep involvement in a disease process. This assay has been approved by the U.S. Food and Drug Administration for testing throat specimens collected using an ESwab Collection kit. This laboratory is certified under the Clinical Laboratory Improvement Amendment of 1988 ("CLIA") as qualified to perform high complexity clinical testing.
