![]() ![]() "It might get some false negatives, however, so that’s why the sample is sent for further testing to determine if it is a true false negative," Stanley said. Stanley said rapid tests are useful in providing a quick answer, and to help in assisting with outbreaks where you need to test large groups at the same time, such as kids returning to school. "Each type of test has different attributes and can be viewed as a different tool," Brunswick Health and Human Services Director David Stanley said. "It’s similar to asking if you recommend using a screw driver instead of a hammer - the recommendation depends on if you are using a nail or a screw. The test choices - rapid or PCR - are no different." The PCR test should be considered after those showing symptoms result in a negative rapid test or those showing no symptoms result in a positive rapid test. The CDC said those performing COVID-19 testing should account for reduced rapid test accuracy. Patients with symptoms and a negative rapid test are instructed to get a confirmation PCR test, wear a mask and stay home in a separate room, according to the CDC. One in five patients with symptoms and confirmed COVID-19 received a negative rapid test result. That accuracy rate dropped to 41.2% when used to screen those who are asymptomatic compared to the PCR tests, which are nearly 100% accurate. The CDC reported the rapid test had an 80% accuracy rate among those showing symptoms.

"If anything, we are underestimating the number of cases out there." "The number of false positive and false negative results is not significant enough to affect the data on reported number of cases," said Dr. There can be false positive and false negative results. Rapid antigen tests for COVID-19 are inexpensive and can deliver results within 15 minutes, but are they as accurate as we think?Īccording to the CDC, these tests can sometimes give incorrect results.
