Accuracy of the COVID-19 Rapid Antigen Test

All “rapid tests” have an accuracy of around 85-90%. Because of this, each time we perform a RAPID test, we mandate a gold standard rt-PCR test for confirmation. This test is covered by the patient’s insurance or HRSA fund.

FAQ’s about Rapid Tests

What is a rapid test?

It is a point-of-care (clinic), diagnostic, and antigen test that utilizes a mucus sample from the nose (nasal passage) to provide expedited COVID-19 results.

What does it test?

It is used to diagnose an active COVID-19 infection, with a slightly lesser degree of accuracy than RT-PCR and a higher chance of missing an active infection. It is best used when coupled with a molecular PCR test. It is ideal for individuals who need their results within the same hour/day.

What does it cost?

$100 out-of-pocket. The test is not covered by any insurance plans.

How long does it take to get results?

15 minutes. Can take longer depending on the number of samples being processed. At most, results should be published within an hour. You will receive a call about the results, whether positive or negative.
