How soon after exposure should I get tested for COVID-19?
Follow CDC guidance, including getting tested at least 5 full days after your last exposure.
How long do rapid COVID-19 tests take?
Antigen tests* are rapid tests which produce results in 15-30 minutes.
What is a PCR test in the context of COVID-19 testing?
A PCR test stands for polymerase chain reaction test. This is a diagnostic test that determines if you are infected by analyzing a sample to see if it contains genetic material from the virus.
How accurate are COVID-19 at home tests?
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. When you perform an at-home COVID-19 antigen test, and you get a positive result, the results are typically accurate.
What are some symptoms of the COVID-19 Omicron variant?
Omicron was first detected in November 2021 and has become the most dominant strain of COVID-19. Common symptoms are typically less severe than other variants and include cough, headache, fatigue, sore throat and a runny nose, according to the researchers.
What is the incubation period of COVID-19?
Incubation Period. Data suggest that incubation periods may differ by variant of the virus. The incubation period for COVID-19 is thought to extend to 14 days. Meta-analyses of studies published in 2020 identified a pooled mean incubation period of 6.5 days from exposure to symptom onset.
How many days after COVID-19 symptoms are you contagious?
Those who do get infected with mild-to-moderate COVID-19 will likely remain infectious no longer than 10 days after symptoms begin. Individuals with severe-to-critical illness stemming from a COVID infection likely aren’t infectious 20 days after symptoms first began.
How accurate are rapid COVID-19 antigen tests?
Rapid antigen tests are most accurate when they are used in people who have signs or symptoms of COVID-19, especially during the first week of illness. People who test negative may still be infected.
How accurate are COVID-19 at-home tests?
Why PCR is better than the rapid COVID-19 test?
“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.
Which COVID-19 tests are more accurate PCR or antigen tests?
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.
Is it possible to get a false positive test result for COVID-19?
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.
How accurate are at-home COVID-19 rapid antigen tests?
Molecular COVID-19 tests are generally expected to detect the SARS-CoV-2 virus at least 95% of the time when someone is infected. 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.

In its early days, the variant caused an alarming spike in COVID-19 cases in South Africa—they went from 300 a day in mid-November to 3,000 a day at the end of that month. In the first months of 2022, an Omicron subvariant called BA.2 began to spread even faster than other Omicron variants.
How long should I stay in home isolation if I test positive for COVID-19?
If you test positive for COVID-19, stay home for at least 5 days and isolate from others in your home. You are likely most infectious during these first 5 days. Wear a high-quality mask if you must be around others at home and in public. Do not go places where you are unable to wear a mask.
Can At-home rapid tests for COVID-19 give a false negative result?
Rapid at-home tests are more likely to give a false negative result in asymptomatic cases. “If repeat testing is not performed after a negative result, an infection may be missed and people may unknowingly spread the SARS-CoV-2 virus to others, especially if they are not experiencing symptoms,” the FDA tweeted.
How accurate are COVID-19 PCR tests?
PCR tests are very accurate when properly performed by a health care professional, but the rapid test can miss some cases.

What does a faint line on a COVID-19 test mean?
If the window on the testing stick shows two lines, the tester is positive for COVID-19. The opaqueness of the lines also can indicate more, Vail said. If the line is fainter, the patient is likely to be less sick, less infectious, or might be nearing the end of infection, Vail said.

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.
Will I have to pay for my COVID-19 test up front?
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.
When should you take a COVID-19 PCR test instead of a rapid antigen test?
“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.
How accurate are at-home COVID-19 antigen tests?
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.
Can a COVID-19 RT-PCR test be falsely negative?
RT-PCR tests are not perfect, Alland said. “After the first week of infection, there is a decline in virus shedding in the respiratory tract, where tests can become falsely negative,” he said.

What types of COVID-19 tests are available in the US?
Diagnostic tests can show if you have an active COVID-19 infection. Antibody or serology tests look for antibodies in a blood sample to determine if an individual has had a past infection with the virus that causes COVID-19 but cannot be used to diagnose current COVID-19 infection.
