What does a positive COVID-19 antibody test result mean?

A positive result means the test did detect antibodies to the virus that causes COVID-19, and it is possible that you had a recent or prior COVID-19 infection and you have developed an adaptive immune response to the virus.

How long after getting infected will COVID-19 antibodies show up in the test?

An antibody test may not show if you have a current infection because it can take 1–3 weeks after the infection for your body to make antibodies.

Should I get the COVID-19 antibody test after vaccine?

Antibody tests can play an important role in identifying individuals who may have been exposed to the SARS-CoV-2 virus and may have developed an adaptive immune response.

However, antibody tests should not be used at this time to determine immunity or protection against COVID-19 at any time, and especially after a person has received a COVID-19 vaccination.

How much does the COVID-19 vaccine cost without insurance?

COVID-19 vaccines are available for everyone ages 5 years and older at no cost. Vaccines were paid for with taxpayer dollars and will be given free of charge to all people living in the United States, regardless of insurance or immigration status.

What causes false negatives in COVID-19 antibody tests?

Having an antibody test too early can lead to false negative results. That’s because it takes a week or two after infection for your immune system to produce antibodies. The reported rate of false negatives is 20%.

What does a negative SARS-CoV-2 antibody test mean?

A negative result on a SARS-CoV-2 antibody test means antibodies to the virus were not detected in your sample. It could mean:
• You have not been infected with COVID-19 previously.
• You had COVID-19 in the past but you did not develop or have not yet developed detectable antibodies.

What is a false positive COVID-19 antibody test?

Sometimes a person can test positive for SARS-CoV-2 antibodies when they do not actually have those specific antibodies. This is called a false positive.

What are consequences of a false negative COVID-19 test?

Risks to a patient of a false negative test result include: delayed or lack of supportive treatment, lack of monitoring of infected individuals and their household or other close contacts for symptoms resulting in increased risk of spread of COVID-19 within the community, or other unintended adverse events.

What does a negative COVID-19 antigen test result mean in asymptomatic persons?

Negative test results using a viral test (NAAT or antigen) in asymptomatic persons with recent known or suspected exposure suggest no current evidence of infection. These results represent a snapshot of the time around specimen collection and could change if tested again in one or more days.

Can you have a negative antibody test for COVID-19 after vaccine?

The authorized vaccines for prevention of COVID-19 induce antibodies to specific viral protein targets; post-vaccination antibody test results will be negative in individuals without a history of previous natural infection if the test used does not detect the type of antibodies induced by the vaccine.

Does a negative result rule out the possibility of COVID-19?

A negative result does not rule out COVID-19 and should not be used as the sole basis for treatment or patient management decisions. A negative result does not exclude the possibility of COVID-19.

Can a person test negative and later test positive for COVID-19?

Using the CDC-developed diagnostic test, a negative result means that the virus that causes COVID-19 was not found in the person’s sample. In the early stages of infection, it is possible the virus will not be detected.

What does a negative COVID-19 virus test result mean if you have symptoms of COVID-19?

If you test negative for the virus that causes COVID-19, the virus was not detected.

• If you have symptoms of COVID-19:
– You may have received a false negative test result and still might have COVID-19. You should isolate away from others.
– Contact your healthcare provider about your symptoms, especially if they worsen, about follow-up testing, and how long to isolate.

How long do you need to quarantine if you tested negative after coming into close contact to someone with COVID-19?

  • Asymptomatic close contacts should continue to self-quarantine for a full 14 days after last exposure and follow all recommendations of public health authorities.
  • Symptomatic close contacts should continue to self-quarantine until symptom resolution as recommended by public health authorities.

What does it mean if I have a negative rapid test result?

What does it mean if I have a negative rapid test result? A negative test result means that proteins from the virus that causes COVID-19 were not found in your sample. It is possible for this test to give a negative result that is incorrect (false negative).

Is the PCR test for COVID-19 accurate?

PCR tests remain the gold standard for detecting an active COVID-19 infection. The tests have accurately detected COVID-19 cases since the pandemic began. Highly trained clinical professionals are skilled at correctly interpreting PCR test results and notices like this one from the WHO.
