Use:

This test helps to identify a type of antibody called immunoglobulin G (IgG) that is the result of past or recent exposure to COVID-19 also known as the novel coronavirus.

Antibodies developed by the body in response to a viral infection may provide potential immunity against future infection. According to the U.S. Food and Drug Administration, COVID-19 antibody testing may indicate that the person has been exposed to the virus and developed antibodies against it, which may mean that person has at least some immunity to SARS-CoV-2.

Note:
This is not a test for an active infection. The COVID-19 antibody test should not be used as a sole basis to diagnose or exclude infection. This test is different from the COVID-19 PCR Swab test, which indicates if there is an active infection and that the virus is present.1

Who may benefit from this test:

Anyone who knows or thinks they may have had COVID-19 and haven’t had any symptoms for the past 14 days and would like to know if they have developed antibodies.

Anyone who has not been diagnosed with COVID-19, this test may help determine if you may have been previously exposed to the virus. If you were exposed, it can check whether your body has produced antibodies.


Preparation:

None


Test Processing:

1-3 days

Test Limitations:2
  • A false-negative result may occur in patients whose blood is drawn before a patient has produced enough IgG antibodies for the test to detect.
  • Positive results may be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E.
  • Specimens from patients receiving therapeutic doses of Biotin (Vitamin H, B7, or B8) may interfere in immunoassays based on biotinylated reagents.
  • Detection of IgG antibodies against SARS-CoV-2 at present is not yet established to determine long term immunity to the virus or to protect the patient against re-infection by the virus.
  • The results obtained with this test should only be interpreted in conjunction with clinical findings, and the results from other laboratory tests and evaluations.
    • This is especially important if the patient has had recent exposure to COVID-19, or clinical presentation indicates that COVID-19 is likely and diagnostic tests for other causes of illness (e.g., other respiratory illnesses) are negative.
    • In this case, direct testing for the SARS-CoV-2 virus (e.g. PCR testing) should be considered.
  • This test should not be used for screening of donated blood.
1 The COVID-19 PCR Swab test is NOT available for collection at HNL Lab Medicine's Patient Centers. The COVID-19 PCR Swab test is for those individuals who have symptoms or meet the Centers for Disease Control and Prevention's testing criteria.
