Dear Nodar,

Good morning! Thank you for your verification file! In order to analyze the results, we

need to confirm some details with you, would you please kindly answer the following questions:

1. How did you take samples to conduct deifferent tests? (Ag test, IgG/IgM test, PCR test)

Did you take 2 nasal swabs and 1 blood sample to perform FIA test, PCR test, IgG/IgM test ? If so, did you take the nasal swabs from the same nostril?

2. Did you do the FIA Ag tests immediately after taking the nasal swabs? And then transfer the another nasal swab to Lugar

laboratory in UTM tube？

3. Does the date on the excel file mean the day, when you conduct test? If so, do you know the symptom onsite date of the patients?

Above all are details, which need to be confirmed. Would you please kindly send me the answers.

Thank your for your collaboration in advance and look forward to your quick reply!

Best Regards/С уважением,

Hebe Luo
