We are seeing a rash of negative PCR test results on patients who clearly are Covid positive clinically (CT evidence is positive). Has there been a mutation of the virus which would cause current testing methods to be negative?
The elegant paper bioRxiv preprint doi: https://doi.org/10.1101/2020.11.03.367391, Christian Gaebler, many et al. Indicates SARS-CoV-2 antibodies do decay but remain for in most people for at least 6 months and that memory B cells are retained and positively modified for long lasting protection. This data suggests reinfection over a year or two is unlikely and that vaccination should provide timely protection.
Is your lab experiencing new reagent or materials shortage for SARS-CoV-2 testing? If so for what components? Is this a new shortage, or continuation of ongoing? Trying to understand the possible impact on test volumes of reagent availability in the current period.
