Is there a test for COVID-19?
Yes, the FDA has issued Emergency Use Authorizations (EUAs) for different types of COVID-19 tests. Some tests are used to diagnose the virus that causes COVID-19 infection whereas other tests are used to detect a recent or prior COVID-19 infection.
What is the fastest rapid test for COVID-19?
The fastest test currently available, ID NOW by Abbott, can detect the virus in 13 minutes or less. Rapid tests can also be done at point-of-care, without requiring an outside laboratory for processing samples. With standard tests, samples are sent to a lab.
Where can I pick up rapid Covid test kits?
Walmart has a full selection of rapid testing kits that are available to purchase online, are FDA-approved and shipping in time for the holidays. See more at Walmart.com. Amazon also has a new rapid Covid test kit that’s available online here, with results in 15 minutes.
How long does it take to get results for a COVID-19 antigen test?
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.

What is the difference between the types of tests available for COVID-19?
See full answer
There are two different types of tests – diagnostic tests and antibody tests. A diagnostic test can show if you have an active coronavirus infection and should take steps to quarantine or isolate yourself from others.
Currently there are two types of diagnostic tests – molecular (RT-PCR) tests that detect the virus’s genetic material, and antigen tests that detect specific proteins on the surface of the virus. Samples are typically collected with a nasal or throat swab, or saliva collected by spitting into a tube.
An antibody test looks for antibodies that are made by the immune system in response to a threat, such as a specific virus. Antibodies can help fight infections. Antibodies can take several days or weeks to develop after you have an infection and may stay in your blood for several weeks after recovery.
When are antigen tests the better option to screen for COVID-19?
The clinical performance of diagnostic tests largely depends on the circumstances in which they are used. Both antigen tests and NAATs perform best if the person is tested when their viral load is generally highest. Because antigen tests perform best in symptomatic people and within a certain number of days since symptom onset, antigen tests are used frequently on people who are symptomatic. Antigen tests also may be informative in diagnostic testing situations in which the person has a known exposure to a person with COVID-19.
What does a positive COVID-19 antigen test result mean?
Positive test results using a viral test (NAAT or antigen) in persons with signs or symptoms consistent with COVID-19 indicate that the person has COVID-19, independent of vaccination status of the person.
Can COVID-19 be identified using an antigen test?
Antigen tests are commonly used in the diagnosis of respiratory pathogens, including influenza viruses and respiratory syncytial virus. The U.S. Food and medicine Administration (FDA) has granted emergency use authorization (EUA) for antigen tests that can identify SARS-CoV-2.
Are COVID-19 molecular tests more accurate than antigen tests?
Molecular tests are generally more accurate and mostly processed in a laboratory, which takes longer; antigen tests—which are sometimes referred to as ‘rapid tests’—are processed pretty much anywhere, including in doctor’s office, pharmacies, or even at home.
Do I need to confirm a negative antigen test with another test if I have the COVID symptoms?
A negative antigen test result for a symptomatic person should be confirmed with a laboratory-based NAAT. A negative antigen result for a symptomatic person may not need confirmatory testing if the person has a low likelihood of SARS-CoV-2 infection (see above).
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.
Do rapid COVID-19 tests detect the COVID-19 variant Omicron?
Makers of both polymerase chain reaction and rapid antigen tests have said their tests can detect omicron.
Is the Innova COVID-19 Antigen Rapid Qualitative Test recommended by the U.S. Food and medicine Administration (FDA)?
The U.S. Food and medicine Administration (FDA) is warning the public to stop using the Innova Medical Group SARS-CoV-2 Antigen Rapid Qualitative Test for diagnostic use. The FDA has significant concerns that the performance of the test has not been adequately established, presenting a risk to health.
How accurate are at home COVID-19 tests?
Home tests will miss some infections and in rare cases mistakenly indicate an infection. One popular test misses around 15 out of 100 infections — these are called “false negatives” — and gives a false positive result in about 1 in 100 people who aren’t infected.
Do COVID-19 tests check for the delta variant and other variants?
There are no authorized COVID-19 antigen or molecular tests that specifically report the presence of the SARS-CoV-2 delta variant. Currently, COVID-19 tests are designed to check broadly for the SARS-CoV-2 virus, including the SARS-CoV-2 delta variant.
Can the Assure COVID-19 IgG/IgM Rapid Test Device be used to diagnose COVID-19?
The Assure COVID-19 IgG/IgM Rapid Test Device should not be used to diagnose acute SARS-CoV-2 infection.
What is the Innova COVID-19 Antigen Rapid Qualitative Test?
The Innova Medical Group SARS-CoV-2 Antigen Rapid Qualitative Test claimed to determine if a person had an active COVID-19 infection. The test uses a nasal swab sample and test strip to detect specific proteins, called antigens, from the SARS-CoV-2 virus. If the nasal sample had SARS-CoV-2 antigens, a colored test line should have appeared on the test strip indicating a person may have COVID-19. If the nasal sample did not have SARS-CoV-2 antigens, a colored line should not have appeared on the test strip. The test has not been authorized, cleared, or approved by the FDA.
