Ethos Laboratories SARS-CoV-2 MALDI-TOF Assay
- GTR Test IDHelpEach Test is a specific, orderable test from a particular laboratory, and is assigned a unique GTR accession number. The format is GTR00000001.1, with a leading prefix 'GTR' followed by 8 digits, a period, then 1 or more digits representing the version. When a laboratory updates a registered test, a new version number is assigned.: GTR000592448.2

Clinical microbial testHelpIn the U.S., clinical tests must be performed under CLIA certification. When a lab uses the same methods for a test in both clinical and research settings, the test appears as two separate GTR records. for Asymptomatic COVID-19

Clinical validity
HelpHow consistently and accurately the test detects or predicts the intermediate or final outcomes of interest. Lab-provided.A total of 107 clinical nasopharyngeal swab specimens (54 negatives and 53 positives for SARS-CoV-2) were tested with the Ethos Laboratories SARS-CoV-2 MALDI-TOF Assay and the results were compared to results obtained with the CDC 2019-Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel (EUA200001). Samples were extracted using the KingFisher Flex Purification System, reverse transcription RT-PCR was performed using the Veriti 96 Thermal Cycler and MALDI-TOF spectrometry was performed on the Agena MassARRAY System. Total Percent Agreement was 104/107 = 97.2%.

The SARS-CoV-2 virus can be detected up to 56 hrs. following sample collection.Comments about the test interpretation (e.g. clinical implication of test results)
1. Negative: RNase P detected, all SARS-CoV-2 targets not detected 2. Positive: RNase P detected or not detected, two or more SARS-CoV-2 targets detected 3. Inconclusive: RNase P detected or not detected, only one SARS-CoV-2 target detected 4. Invalid: RNase P not detected, all SARS-CoV-2 targets not detectedMinimal microbe load test can detect
