Q1: Is the Quick SARS-CoV-2 Multiplex Kit a diagnostic test?
This test has not ben FDA cleared or approved. In the USA this test can be adopted in clinical diagnostics laboratories as an LDT according to local state guidelines. The test can be used for RUO/Informational purposes. The test is currently pending for CE IVD certification.
Q2: Can I use Quick SARS-CoV-2 Multiplex Kit for the detection of pathogens other than SARS-CoV-2?
This test detects specifically SARS-CoV-2 and cannot be used to detect other viruses or pathogens.
Q3: I cannot interpret the results.
Please refer to the Interpretation of Results, the Appendix, and the Troubleshooting Guide sections in our Quick SARS-CoV-2 Multiplex Kit protocol. If you still have problems with the result interpretation please contact our Technical Support team at (949) 679-1190 ext. 3 or e-mail us at tech@zymoresearch.com.
Q4: Amplification curves look strange.
Sometimes aberrant qPCR signal are observed. Please refer to the Interpretation of Results, the Appendix, and the Troubleshooting Guide sections in our Quick SARS-CoV-2 Multiplex Kit protocol. If you still have problems with the result interpretation please contact our Technical Support team at (949) 679-1190 ext. 3 or e-mail us at tech@zymoresearch.com.
Q5: The No-Template Control show an amplification signal. What should I do?
This may indicate incorrect plate set-up or a contamination in the No-Template Control or in the 2X CV Mix. We recommend repeating the test, and if the problem persists to use a new aliquot of reagents.
Q6: The CV Positive Control doesn’t amplify. What should I do?
If using RT-PCR instruments different than the CFX96 Touch from Bio-Rad, this problem can be solved by adjusting the RT-PCR parameters (e.g. baseline threshold, temperature ramp, ...).
This problem may also indicate incorrect plate set up of the compromise of Quick SARS-CoV-2 reagents.

Q7: RNase P human target (Quasar 670®) amplified after cycle 40 or didn’t amplify at all. How do I interpret the results?
If the host target didn’t amplify or shows CT values above 40, your RNA extraction and/or RT-PCR reaction may have been incorrectly performed. We suggest repeating RNA extraction and the RT-PCR reaction.
Q8: Signal for SARS-CoV-2 viral targets (HEX™ channel) was detected late, between cycle 35 and 45. Is this a valid signal? How do I interpret the results?
Late signal for SARS-CoV-2 viral targets may be indicative of a low viral load in your sample. We suggest repeating the RT-PCR to confirm results.
Q9: How the Quick SARS-CoV-2 rRT-PCR Kit performs compared to other FDA EUA and CE-IVD molecular tests?
With a limit of detection(LoD) as low as 10 GEC/reaction the Quick SARS-CoV-2 Multiplex Kit outperforms most of the SARS-CoV-2 molecular tests present on the market.
In addition, the detection of a host target (human Rnase P) allow the identification of insufficient samples, which other tests may classify as negative; this further reduce the chances of the false negative results.
