COVID-19 antibody testing
What is a covid 19 antibody test?
If you’re curious to learn if you have some COVID-19 protection, this test can help. A COVID-19 antibody test is a simple finger prick blood test. It can determine whether you’ve formed antibodies because you received the vaccine or had a coronavirus infection 14 to 21 days ago.
Experts have not yet determined how long this protection could last. However, some studies indicate that these antibodies may remain active for 5 to 7 months after infection or the vaccine.
Even if you test positive for antibodies, you should continue to follow CDC guidance regarding social distancing, frequent hand washing and wear a mask to protect yourself and others.
What do the results of a COVID-19 antibody test mean?
A positive result indicates the presence of antibodies, stemming from either a COVID-19 vaccine or a past infection with the virus. Conversely, negative results suggest no prior infection or the absence of antibody development in response to the vaccine.
Even with a positive antibody test result, continued adherence to CDC guidelines, such as social distancing, regular hand hygiene, and mask usage, is imperative. Positivity does not equate to absolute protection against future COVID-19 infections.
It is important to emphasize that the test is not designed to determine the potential for virus transmission or serve diagnostic or immunity purposes.
How long do COVID-19 antibodies last?
Presently, the exact duration of COVID-19 antibodies remains uncertain. Some research suggests that these antibodies may stay active for 5 to 7 months following infection.
