Brook, MD, ScD.

After nearly two years of the COVID pandemic, life being thrown into constant chaos can feel exhausting. The time taken to test negative after contracting COVID depends on the severity of the case, and also on the test itself.

PCR tests that hunt out parts of viral genetic material RNA in the case of COVID in our bodies and amplify it so we can detect it are extremely sensitive and can even pick up the presence of few viral fragments. This is because fragments of viral RNA can remain in our bodies long after the infection is over and the virus has been cleared from our system.

Lateral flow tests that look for viral proteins called antigens are less sensitive and may be less likely to give a positive result several days after first infection.

If we test positive on a PCR test but negative on an antigen test, then it’s likely that we are not infectious and have just residual virus RNA. Unfortunately, many people can test positive for COVID for weeks or even months, but there is good news: people are not likely to be contagious for that long, even if they test positive, and therefore are unlikely to transmit the virus to others. However, if we test positive on a PCR as well as on a protein-based antigen test, then we might still be infectious.

This is because having viral proteins for a long time means that the virus is replicating and producing more of its core material. The World Health Organization WHO advises that people isolate for ten days after their symptoms start or from when they are diagnosed if they are asymptomatic plus three days after symptoms cease.

There are exceptions to this depending on whether people are still symptomatic, says WHO : if a person is symptomatic for say, 30 days they will need to isolate until they are asymptomatic.

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.

A sample may be collected by using a shorter nasal swab mid-turbinate swab or a very short swab anterior nares swab. In some cases, health care professional inserts a long swab into the back of your throat oropharyngeal swab.

Or you may spit into a tube to produce a saliva sample. 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.

RT-PCR tests are very accurate when properly performed by a health care professional, but the rapid test can miss some cases. Antigen test. 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.

A positive antigen test result is considered accurate when instructions are carefully followed. 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. Depending on the situation, the health care provider may recommend a RT-PCR test to confirm a negative antigen test result. Only a single sample is needed to check for all three viruses.

This could be helpful during the flu season. But a negative result does not rule out the possibility of any of these infections. So the testing process may include more steps, depending on symptoms, possible exposures and your provider’s clinical judgment. In the U. Certain groups are considered high priority for diagnostic testing. Other people may be given priority for testing depending on local health department guidelines for monitoring COVID in individual communities. People with no symptoms can be tested.

The availability of COVID diagnostic testing and where to get tested may vary depending on where you live and the recommendations of your local public health officials.

If you have symptoms, you risk unknowingly spreading the virus to others if you don’t take proper precautions, such as wearing a face mask when appropriate.

There’s also a chance that a COVID rapid antigen test can produce false-positive results if you don’t follow the instructions carefully. False-positive results mean the test results show an infection when actually there isn’t one. The risk of false-negative or false-positive test results depends on the type and sensitivity of the COVID diagnostic test, thoroughness of the sample collection, and accuracy of the lab analysis. They often give inaccurate results.

Whether or not you have symptoms, plan to wear a face mask to and from your provider’s office or the testing center. If you have no symptoms and don’t think you’ve been in contact with someone with COVID , but you want to get tested, ask your health care provider or testing center whether and where testing is available.

Or you can call your state or local health department or visit their website for information on testing. For a COVID diagnostic test, a health care professional takes a sample of mucus from your nose or throat, or a sample of saliva.

The sample needed for diagnostic testing may be collected at your doctor’s office, a health care facility or a drive-up testing center. Nose or throat swab. A long nasal swab nasopharyngeal swab is recommended, though a shorter or very short nasal swab or throat swab is acceptable. A health care professional inserts a thin, flexible stick with cotton at the tip into your nose or brushes the swab along the back of your throat to collect a sample of mucus.

This may be somewhat uncomfortable. For the nasal sample, swabbing may occur in both nostrils to collect enough mucus for the test. The swab remains in place briefly before being gently rotated as it’s pulled out. The sample gets sealed in a tube and sent to a lab for analysis. If you have a productive cough, your health care provider may collect a sputum sample, which contains secretions from the lungs, a part of the lower respiratory system. The virus is more concentrated in the nose and throat early in the course of the infection.

But after more than five days of symptoms, the virus tends to be more concentrated in the lower respiratory system. In addition to the COVID diagnostic test, your health care provider may also test for other respiratory conditions, such as the flu, that have similar symptoms and could explain your illness.

Some of these tests require a provider’s prescription. You collect your own sample of nasal fluid or saliva at home and then send it to a lab to be rapidly analyzed.
