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. If people without symptoms have a positive test result, they should follow guidelines for self-isolation to help curb the spread of the virus. 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. You can buy some antigen tests over the counter with no prescription needed, though antigen tests are not considered as reliable as PCR tests.
The benefits of an at-home test are you can take it at home and get quick results. It's a fast and easy way to test yourself as soon as you have symptoms or at least five days after you've been exposed to the COVID virus. It's also an option if you want to make sure you don't have the virus before meeting in groups with others, to ensure you don't accidentally spread it.
If you test negative, taking the test a second time a few days later can help ensure your test results are accurate. The accuracy of each of these tests varies. Only get an at-home test that's authorized by the FDA or approved by your doctor or local health department. The purpose of this video is to prepare children for a COVID nasal swab test, to help ease some of their potential fear and anxiety.
When children are prepared to take a medical test, they become more cooperative and compliant, which creates a positive coping experience for them. This video has been made to be watched by children as young as 4 years old. My job is to help kids like you prepare for medical tests.
You may have heard there is a virus going around that can make people feel sick. A virus is a germ and it is so tiny you can't even see it. Some people who get this virus can have a fever or a cough and may feel achy and tired, while some people can have this virus and not feel sick at all. People may get this virus from touching things. That's why it's important to wash your hands often with soap and water.
The virus also can spread through a cough or a sneeze. So it's important to always cover your cough or sneeze. Today, even though you may or may not be feeling sick, we will need to give you a test so we know how to best proceed with your medical care.
This medical test will tell us if you have the virus. When you go to take your test, the health care provider will wear special protective clothing. They wear this clothing to keep themselves and you safe from getting germs. They will wear a mask to cover their nose and mouth and a clear plastic shield to protect their eyes. The most important thing you can do during your test is to sit perfectly still like a statue.
To help make sure you don't move, your parent or caregiver will help keep you still and calm during your test. The health care provider needs to touch the inside of the back of your nose with a long, skinny Q-tip.
To do this, you need to hold your chin up, then the health care provider will put the Q-tip in your nose for a short time to collect a sample. While this happens you may feel like you want to push the Q-tip away, but it's really important to stay as still as possible so the health care provider can finish the test. The Q-tip will be in and out of your nose in a few seconds. Some kids tell me that counting to 3 or taking a deep breath relaxes them before the test happens, and some tell me they like to hold on to their favorite stuffed animal or blanket.
