Considering the statements below, from a randomly selected fact sheet FDA approved under Emergency Use Authorization or EUA, the current antibody testing lacks scientific validity. This is really sad that such tests [kits] are being promoted or used to establish COVID-19 [1]. As noted below the test monitors protein levels commonly known as [IgM, IgA and IgG] not specifically COVID-19. Logically data obtained from such tests should be avoided in making predictions or projections about the infection and its spread. It certainly is false science.
1. “A positive result with VITROS Immunodiagnostic Products Anti-SARS-CoV-2 Total Reagent Pack test may not mean that an individual’s current symptoms are due to COVID-19 infection.”
2. “However, a negative result does not rule out COVID-19.”
3. “The absolute sensitivity of the VITROS Immunodiagnostic Products Anti-SARS-CoV-2 Total Reagent Pack test is unknown.”
4. FDA statement [2] “This limits the test’s effectiveness for diagnosing COVID-19 and why it should not be used as the sole basis to diagnose COVID-19.”
In addition, if vaccines would be developed based on such antibody tests, which do not appear to be sufficiently validated as noted above, then how reliable and valid vaccines would be? Please be cautious with claims in this regard.
