But they can still spread the virus that causes COVID-19 to others. Some people who have COVID-19 may not have symptoms (asymptomatic). Other people may be given priority for testing depending on local health department guidelines for monitoring COVID-19 in individual communities.

Live or work in long-term care facilities, such as nursing homes, or other places where people are housed closely together, such as prisons or shelters.

Work in a health care facility or as first responders.

These include people with COVID-19 signs and symptoms who: You don't need to be tested if you've had COVID-19 in the last three months.Д¬ertain groups are considered high priority for diagnostic testing.

You're required to take a test for screening purposes, such as at some schools or workplaces.

Your health care provider, other health care professional or your public health department recommends a test and you're not fully vaccinated.If you've had close contact with someone who has the COVID-19 virus, get tested at least five days after you've had contact with them. Close contact means you've been within 6 feet (2 meters) of a person who has COVID-19, or you live with someone with COVID-19. You've had close contact with someone with COVID-19.You have COVID-19 symptoms, such as fever, cough, tiredness or shortness of breath.

In the U.S., a COVID-19 diagnostic test may be needed if: So the testing process may include more steps, depending on symptoms, possible exposures and your provider's clinical judgment. But a negative result does not rule out the possibility of any of these infections. This could be helpful during the flu season.

Only a single sample is needed to check for all three viruses. Depending on the situation, the health care provider may recommend a RT-PCR test to confirm a negative antigen test result.ДЄ RT-PCR test called the Flu SC2 Multiplex Assay can detect any of three viruses at the same time: the COVID-19 virus, influenza A and influenza B (flu). But there's an increased chance of false-negative results - meaning it's possible to be infected with the virus but have a negative result. Others may be sent to a lab for analysis.ДЄ positive antigen test result is considered accurate when instructions are carefully followed. Using a long nasal swab to get a fluid sample, some antigen tests can produce results in minutes. This COVID-19 test detects certain proteins in the virus. RT-PCR tests are very accurate when properly performed by a health care professional, but the rapid test can miss some cases.ДЄntigen test. Results may be available in minutes if analyzed onsite in 1 to 3 days - or longer in locations with test processing delays - if sent to an outside lab. Or you may spit into a tube to produce a saliva sample. In some cases, health care professional inserts a long swab into the back of your throat (oropharyngeal swab). A sample may be collected by using a shorter nasal swab (mid-turbinate swab) or a very short swab (anterior nares swab). A health care professional collects a fluid sample by inserting a long nasal swab (nasopharyngeal swab) into your nostril and taking fluid from the back of your nose. Also called a molecular test, this COVID-19 test detects genetic material of the virus using a lab technique called reverse transcription polymerase chain reaction (RT-PCR).
