Establish or confirm diagnosis
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%.

How long can the microbe be present after therapy (rendering consequent tests meaningless)
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 detected
Minimal microbe load test can detect
1 TCID50/mL with 100% accuracy.
