Fluidigm Corporation announced that Helix Specialty Diagnostics is partnering with Genomic LTC DX to provide COVID-19 testing using the Advanta™ Dx SARS-CoV-2 RT-PCR Assay on the Fluidigm® Biomark™ HD system. Both Missouri based companies operate major Clinical Laboratory Improvement Amendments (CLIA) certified labs. Helix Specialty Diagnostics leads sample collection for the collaboration, with Genomic LTC DX processing and analyzing the saliva samples via the Advanta Dx Assay on the Biomark HD. Fluidigm has received Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA) for the Advanta Dx SARS-CoV-2 RT-PCR Assay, an extraction-free saliva-based test to detect nucleic acid from the SARS-CoV-2 virus. The assay does not require collection via invasive nasopharyngeal swab, and the company’s submission to the FDA demonstrated 100% agreement between saliva results from the Advanta Dx Assay and results from paired nasopharyngeal samples tested with authorized assays. A growing body of peer-reviewed research is confirming that the accuracy of saliva-based COVID-19 testing is comparable to that of nasopharyngeal-based collection. A systematic review and meta-analysis published in JAMA Internal Medicine in January 2021 stated that saliva-based tests have a similar sensitivity and specificity and present an attractive alternative to invasive nasopharyngeal testing. Fluidigm continually conducts in silico analyses to determine the effectiveness of the Advanta Dx Assay design to detect SARS-CoV-2. To date, none of the published viral mutations meaningfully impact the regions of the viral genome targeted by the assay’s primers and probes. The Advanta™ Dx SARS-CoV-2 RT-PCR Assay is a real-time Reverse Transcription (RT) PCR test intended for the qualitative detection of nucleic acid from the SARS-CoV-2 in saliva specimens collected without preservatives in a sterile container from individuals suspected of COVID-19 by their healthcare provider. Testing is limited to Laboratories which are certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), 42 U.S.C. §263a, and meet requirements to perform high complexity tests. Results are for the identification of SARS-CoV-2 RNA. The SARS-CoV-2 RNA is generally detectable in saliva specimens during the acute phase of infection. Positive results are indicative of the presence of SARS-CoV-2 RNA; clinical correlation with patient history and other diagnostic information is necessary to determine patient infection status. Positive results do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of disease. Laboratories within the United States and its territories are required to report all results to the appropriate public health authorities. Negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations, patient history, and epidemiological information. Negative results for SARS-CoV-2 RNA from saliva should be confirmed by testing of an alternative specimen type if clinically indicated. The Advanta™ Dx SARS-CoV-2 RT-PCR Assay is intended for use by qualified and trained clinical laboratory personnel specifically instructed and trained in the techniques of real-time PCR and in vitro diagnostic procedures. The Advanta™ Dx SARS-CoV-2 RT-PCR Assay is only for use under the Food and Drug Administration's Emergency Use Authorization. Other Fluidigm products are provided for Research Use Only. Not for use in diagnostic procedures.
