Antibody Profile for COVID-19 Recovery Certification (Serum/Plasma)
This test measures antibodies in your blood that your immune system produces after recovering from COVID-19. These antibodies help confirm past infection and may indicate immunity.

Why This Test Is Done
Your healthcare provider may recommend this test if you’ve had COVID-19 symptoms or a positive test result and want to check for antibodies that suggest recovery. It may also be used for certification purposes, such as returning to work or travel, depending on local guidelines.
What to Expect Before the Test
No special preparation is needed. You’ll likely have a small needle inserted into your arm to draw blood. If you’re nervous, let your healthcare provider know so they can help make it more comfortable.
What the Test Measures
The test detects specific antibodies (IgG and IgA) produced by your immune system in response to the SARS-CoV-2 virus. These antibodies are signs that your body has recognized and fought off the virus.
How the Results Are Used
Positive results (detecting antibodies) suggest you’ve likely recovered from COVID-19 and may have some level of immunity. However, antibodies may not last forever, and immunity can vary. Results are used to support decisions about returning to activities or confirming past infection status.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Antibody presence does not guarantee lifelong immunity but may indicate a stronger immune response. It can help differentiate between past infection and current exposure. However, antibody levels can decline over time, so repeated testing may be needed for ongoing certification purposes.
