A member asked:

In nov. 2020. i had covid-19, and in jan 2021. my antibody titer was 32,09 u/ml. however, repeated antibody serology showed titer of 406,0 u/ml in jul. 2021. i havent been vaccinated yet. how is that possible?

Antibody titers are not recommended for follow-up of infection or vaccination. Your titer may have gone up due to a subsequent clinically silent infection with a different strain of the virus. Get vaccinated. Wish you good health!
