COVID-19 Antibody Testing

  • Detects body’s immune response to COVID-19 by measuring specific antibodies associated with COVID-19 (SARS-CoV-2)
  • Any positive results should be confirmed using the COVID-19 PCR Test.
  • Follow-up testing with the COVID-19 PCR Test should also be considered to rule out infection in individuals with a negative COVID-19 Antibody Test who exhibit symptoms of COVID-19
  • Blood draw required
Please note that negative results do not rule out SARS-CoV-2 infection. Results from the COVID-19 Antibody Test should not be used as the sole basis for diagnosis or exclusion of a SARS-CoV-2 infection. This COVID-19 antibody test is based on a unique fragment of the nucleoprotein from COVID-19 (SARS-Cov-2). Antibodies, IgM and IgG, generated against this fragment have been demonstrated NOT to cross-react with other viruses, including other coronavirus strains. Follow-up testing with the COVID-19 PCR test should be considered to rule out infection in individuals with negative serological results who exhibit symptoms of COVID-19.

COVID-19 Antibody Testing is available to all Evexia clients, including non-licensed clinicians. For all non-licensed client orders, a $15 physician network fee will apply and our phlebotomy network must be utilized for sample collection and shipping.

  • About 10% to 15% of the antibodies present in the body are IgA antibodies.
  • A small number of people do not make IgA antibodies.

IgG –

  • IgG antibodies are found in all body fluids.
  • IgG antibodies are the smallest but most common antibody (75% to 80%).
  • IgG antibodies are very important in fighting bacterial and viral infections.
  • IgG antibodies are the only type of antibody that can cross the placenta in a pregnant woman to help protect the fetus.

IgM –

  • IgM antibodies are found in blood and lymph fluid and are the first type of antibody made in response to an infection.
  • IgM antibodies also cause other immune system cells to destroy foreign substances.
  • IgM antibodies are the largest antibody and make up about 5% to 10% of all the antibodies in the body.

Evexia Diagnostics does not accept any form of insurance nor do we have the ability to seek third-party reimbursement. We are offering this test as a convenience to our clients and their patients, who may not be able or may choose not to travel to a location where the test can be charged to a third-party. The fees charged by Evexia to our clients for the COVID-19 test are a reflection of our cost related to the acquisition and distribution of the COVID-19 test and supplies. Anyone who is symptomatic and/or who meets the CDC’s guidelines for testing has the option of receiving the test for free, but they would need to locate a testing facility (clinic, drive-thru or hospital) that is able to seek 3rd-party reimbursement and have the testing done there.
