Differences Between Rapid & PCR Tests | PhysicianOne Urgent Care.
The rapid test offers a faster turnaround time—often providing results within 15 minutes. Patients who receive the PCR test will likely wait at least two days for results, and during periods of high demand, results may not be available for up to a week. Another important difference between the two tests is the accuracy rate.
Experts say the rapid antigen test is quite likely to be accurate for patients who test positive for COVID If you have additional questions about our services or locations, contact us today. Brie Rahoi was wonderful and very helpful. I received excellent care. Friendly and prompt check in. The test detects the presence of a virus if you are infected at the time of the test. The test could also detect fragments of the virus even after you are no longer infected.
Most of the time, PCR tests are extremely accurate; the only drawback being the amount of time between getting tested and getting a definitive answer.
Typically, that process lasts anywhere from days. According to Harvard Medical School :. They are sometimes referred to as rapid diagnostic tests because it can take less than an hour to get the test results. Positive antigen test results are highly specific, meaning that if you test positive you are very likely to be infected.
Antigen tests, while offering results within minutes with great accuracy, can return a higher rate of false negatives than the PCR test.
Test too early or too late and it may result in a false negative — but, antigen tests will detect active infection. You can even perform antigen tests at home — the Department of Health and Human Services will now send you four for free if you visit CovidTests. Come see us and we can perform antigen tests on-site at Lincoln Urgent Care. This new test returns PCR results in as little as 30 minutes.

An antigen test is a rapid test, while the PCR test traditionally takes a few days to return results. When the outbreak of a highly transmissible disease starts, the first line of action should be early testing and diagnosis of the virulent.
Early testing leads to rapid identification of infected persons, or quick treatment, and taking all the necessary preventive measures to prevent the spread of the diseases. All tests are different as each detects a distinct part of the virus.
Test speed and its accuracy are also different in these tests. Antigens are the proteins present on the outer shell of the virus. Antibodies are produced in our body against specific antigens to protect our body from infection. For conducting any test that detects COVID infection, the first step is to collect the sample from the suspected person.
A health care worker takes a sample of secretion from the nostrils and the nasopharynx using a long swab with a soft end. It means that if someone has COVID 19 infection, higher are the chances of this test giving a positive result.
It can also detect residual viruses even after the person has recovered fully. After collecting a sample from a person, the pathologist extracts the RNAs host and virus both from the sample secretion. The genetic material RNAs of the virus is created with the help of a reverse transcriptase enzyme and amplification in the laboratory.
After recovering genetic material, a fluorescent dye is used that identifies if the virus is present or not. The entire process of fluorescent dye takes up to 8 hours to detect whether the sample is positive or negative.
