Corona/COVID-19 Selftest Warning - Bert Hubert's writings
a day ago
- COVID-19 self-test kits currently sold are likely fake, ineffective, and could harm users.
- Serological tests detect antibodies, not the virus, and only work days or weeks after infection.
- Positive results for IgG but negative for IgM may indicate past infection and immunity, but this is not validated.
- Validated tests may appear in the future, but as of mid-March 2020, no reliable test is available to the public.
