Covid-19 Antibody Testing

COVID-19 Antibody Testing for Phoenix Arizona

Are you curious whether you’ve been exposed and/or infected with COVID-19? Many people who have tested positive for the virus did not have any prior symptoms. Did you have an upper respiratory illness in November or December, or early 2020 and now questioning whether that may have been COVID-19? Do you want to be a part of the effort to determine the actual spread of COVID-19?

If so, you can either order a COVID-19 antibody test and you can test yourself in the privacy of your own home, OR, come to one of our Covid-19 testing stations and we’ll administer the antibody test for you on the spot.

Our antibody tests are far more thorough than many of the available antibody tests available because it tests for 3 different antibody levels, IgM, IgA, and IgG. This will help lower the possibility of a false negative test. (Receiving a negative result when you have indeed been infected with COVID-19.)

USA Covid Labs antibody test has been validated by FDA EUA (Emergency Use Authorization) standards and authorized for use.

What will the test show me?

A COVID-19 antibody test is different than the nasal swab test that checks for the presence of the COVID-19 virus itself. The antibody test can tell you whether you have been infected by Covid-19 and if your body has generated antibodies against the virus.

What is an antibody test?

An antibody test reveals whether a person’s immune system has developed antibodies needed to fight off a specific infection which, in this case, is Covid-19. A positive test means a person has the antibodies, and therefore had the virus at some point. A negative test means a person does not have the antibodies and has not yet contracted the virus. An antibody test is especially important for detecting previous infections with few or no symptoms.

What kind of antibodies does this test for?

Most commercial COVID-19 antibody tests available now check for IgG antibodies only. This means that you may have a false negative test if your immune system has not developed IgG antibodies yet. This can occur during early infection or exposure or if your immune system is slow to generate IgG antibodies. Testing for all 3 common antibodies is a more thorough way to test and will lead to less false negative testing.

USA Covid Labs antibody tests check for all 3 immunoglobulin antibodies.

IgM – Immunoglobulin M
This test detects IgM antibodies. IgM is usually the first antibody produced by the immune system when a virus attacks. A positive IgM test indicates that you may have been infected and that your immune system has started responding to the virus. When IgM is detected you may still be infected, or you may have recently recovered from a COVID-19 infection.

IgA – Immunoglobulin A
This test detects IgA antibodies which rises soon after viral exposure, usually within the first 3-6 days. IgA is found mainly in the respiratory and digestive tracts.

IgG – Immunoglobulin G
This test detects IgG antibodies that develop in most patients within 7 to 10 days after exposure to COVID-19. IgG antibodies remain in the blood after an infection has passed. These antibodies indicate that you may have had COVID-19 in the recent past and have developed antibodies that may protect you from future infection. It is unknown at this point how much protection antibodies might provide against reinfection.
