Common Cold May Trigger Positive COVID-19 Antibody Test
STORY AT-A-GLANCE
There are three types of COVID-19 tests: molecular, antigen and antibody. Molecular and antigen tests detect active infections, whereas the antibody test will tell you if you’ve developed antibodies in response to a previous SARS-CoV-2 infection
There are seven different coronaviruses known to cause respiratory illness in humans. The antibodies created by these different coronaviruses appear very similar, and recovering from the common cold may trigger a positive antibody test for COVID-19, even if you were never infected with SARS-CoV-2 specifically
While experts at the Mayo Clinic claim cross-reactive antibody tests were an early problem that has been corrected and eliminated, the CDC has not confirmed this
A Singaporean study found common colds caused by the betacoronaviruses OC43 and HKU1 appear to make you more resistant to SARS-CoV-2 infection, and that the resulting immunity might last as long as 17 years
Other studies suggest immunity after COVID-19 infection may only last between two and 12 months
