Antigen Rapid Test for SARS-CoV-2 (COVID-19) Antibody Detection (Serum/Plasma)

How the Test Works

The test uses a rapid immunoassay method to identify specific antibodies (immunoglobulins) in your serum or plasma. These antibodies are produced by your immune system after exposure to the SARS-CoV-2 virus. The test detects antibodies that bind to viral proteins, indicating a past infection.

What to Expect Before the Test

No special preparation is needed. You may have blood drawn from a vein in your arm, or a small sample may be collected via fingerstick. The test is typically performed on a small blood sample taken during a routine blood draw or at a testing site.

What the Test Results Mean

A positive result suggests you may have been previously infected with COVID-19 and developed antibodies. A negative result means the test did not detect antibodies at this time, but it does not rule out past infection. False negatives can occur, especially if tested too soon after exposure.

Limitations and Considerations

This test is a screening tool and may not detect all types of antibodies. It is not a diagnostic test for current COVID-19 infection. Results can vary based on the timing of testing after exposure and the individual’s immune response.
