SARS-CoV-2 Antibody (Qualitative) in Saliva by Rapid Immunoassay
This test detects antibodies in your saliva that your immune system produces in response to exposure to the virus that causes COVID-19. It helps determine if you may have been infected at some point.
["A positive result suggests past exposure to COVID-19, but it does not confirm current infection."]

How the Test Works
Your saliva sample is tested using a rapid immunoassay method. This detects specific antibodies (IgM and IgG) that your body creates after exposure to the virus. The test uses a chemical reaction to show whether these antibodies are present.
What to Expect Before the Test
No special preparation is needed. You can collect saliva by letting it drip into a provided collection tube or swab. Avoid eating, drinking, or brushing your teeth for 30 minutes before testing.
What the Results Mean
A positive result indicates the presence of antibodies, which may mean you had COVID-19 in the past. However, antibodies do not always appear immediately after infection and may take several weeks to develop. A negative result means no detectable antibodies were found in this test.
Limitations and Considerations
This test is qualitative and not designed to diagnose active COVID-19 infection. It may not detect antibodies if you were infected recently or if your immune response is weak. Results can also vary based on the timing of testing after exposure.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Antibody testing in saliva can be useful for screening or monitoring in settings like healthcare facilities, workplaces, or community programs. It may help identify individuals who have been exposed to COVID-19 and could potentially spread the virus, even if they are not currently symptomatic. However, it should not replace other diagnostic tests like PCR for confirming active infection.
