Corona tests performed at home are not a substitute for corona tests performed in health care, according to the Department of Health and Welfare (THL).

According to THL, the home tests available in Finland are antibody tests that can be used to assess whether you have previously suffered from coronavirus disease.

An antibody test cannot reliably determine whether a corona infection has occurred.

Antibody tests are performed on a fingertip blood sample.

The tests detect the body's antibodies against the coronavirus, but not directly against the virus itself.

Antibodies rise to detectable levels in the blood 1 to 3 weeks after infection.

THL recalls that as a symptom you have to go for a corona test in health care.
