“PCR tests are more reliable and accurate due to testing the specific genetic material of the virus, eliminating the interference from other viruses,” said Heather Seyko, a Laboratory Services manager for OSF HealthCare.
This COVID-19 test detects certain proteins in the virus. Using a long nasal swab to get a fluid sample, some antigen tests can produce results in minutes. Others may be sent to a lab for analysis.

It's possible to have a positive test result even if you never had any symptoms of COVID-19 . False-positive test results can occur. It may be that the test detected antibodies to a coronavirus closely related to the COVID-19 virus or that the test quality was flawed.
However, at-home COVID-19 antigen tests are generally expected to detect the SARS-CoV-2 virus at least 80% of the time when someone is infected.
“PCR would be chosen where there is a low likelihood of having the virus, but we want to be certain the patient doesn't have it. Antigen would be chosen if there is a high probability the patient has the virus (i.e. is experiencing symptoms), and we need to screen the patient as positive or negative,” Heather said.
They reported that the top five symptoms related to the variant were: Runny nose. Headache. Mild or severe fatigue.Sore throat Sneezing
See full answerThe Biden-Harris Administration is strongly incentivizing health plans and insurers to set up a network of convenient locations across the country such as pharmacies or retailers where people with private health coverage will be able to order online or walk in and pick up at-home over-the-counter COVID-19 tests for free, rather than going through the process of having to submit claims for reimbursement. Consumers can find out from their plan or insurer if it provides direct coverage of over-the-counter COVID-19 tests through such a program or whether they will need to submit a claim for reimbursement. If you are charged for your test after January 15, keep your receipt and submit a claim to your insurance company for reimbursement.
People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus.
The investigators also point out that false-positives are possible due to administering the test too early or late in the infectious stage, or from incorrectly performing the self-test.
A false-positive antigen test result means that the test says the person has COVID-19 but they are actually do not have COVID-19.
A faint line also can mean the tester didnt swab well enough to provide a good test sample. A brighter line indicates the patient has more virus in their body and is likely to be sicker and more infectious.
In people who did not have COVID-19, antigen tests correctly ruled out infection in 99.6% of people with symptoms and 99.7% of people without symptoms.
PCR tests are more accurate than antigen tests. "PCR tests are the gold standard for detecting SARS-CoV-2," says Dr. Broadhurst. "It is the most accurate testing modality that we have.
A single antigen test may only be able to correctly identify the virus 60% of the time in patients who have the omicron variant and who display symptoms of the disease, Tim Stenzel, director of the Food and Drug Administration's Office of In Vitro Diagnostics and Radiological Health, said during a Wednesday meetin.
Antigen tests typically give results in just 15 minutes, can be done at home by yourself, and are much less expensive than PCR tests.
