Although scientists do not know how long antibodies to SARS-CoV-2 can be detected, for most other infections, IgM is most useful for determining recent infection as it usually becomes undetectable weeks to months following infection, while IgG may remain detectable for months or years

Could be a recent reinfection or Vaccination induced.

Thank you doctor
