SKU: 164072


Product Description

Test Name: SARS-CoV-2 IgA Antibodies
Synonyms: COVID-19 Antibodies, COVID-19 Serology, COVID-19 Immune Response, Coronavirus Antibodies

This is a qualitative detection of IgA antibodies to SARS-CoV-2, the virus that causes COVID-19, to help identify individuals who have been exposed to the virus. Serologic results should not be used as the sole basis to diagnose or exclude recent SARS-CoV-2 infection. This test is recommended in individuals at least 10 days post symptom onset or following exposure to individuals with confirmed COVID-19.

Serology testing, also known as coronavirus antibody tests, can check for a type of antibody (IgA) developed after exposure to the SARS-CoV-2 virus that causes COVID-19. This type of COVID-19 test is for individuals who think they may have previously had COVID-19 and do not currently have symptoms. The human body produces IgA antibodies as part of the immune response to the virus. On average, IgA antibodies are usually detectable within 3-7 days from the start of the infection. They are found in the linings of the respiratory tract and digestive system, as well as in saliva (spit), tears, and breast milk.

The CDC and healthcare experts recommend you discuss your test results and whether to return to work with your healthcare provider and employer.
