According to Dr. There are some clear indications as to which test you should get and some not so clear reasons. While the rapid test can get you results very quickly, the results may not always be accurate. The false positive rate — meaning I test positive but I do not really have the disease — is quite low. So, if you test positive from a rapid test it is more likely you do have the disease. Current recommendation is to have a confirmation test performed the PCR test if you still have symptoms and have had a negative rapid test.

The total time taken by test to provide results is minutes. Antigen test is a point-of-care test. It means it can be done anywhere, like at the clinic, home, or hospital. Antigen tests are relatively less expensive.
Rapid antigen tests are often used as mass screening tests to detect SARS-CoV-2 infection quickly in containment zones or healthcare settings. It helps in the immediate implementation of infection prevention measures effectively. A rapid antigen test is a simple test. It comes as a kit same as a pregnancy test kit. Before taking the sample, wash your hand for 20 seconds using soap and water. Alternatively, you can use hand sanitizer.
After taking the sample swab from the nose and throat, we can transfer it to the extraction tube and finally to the test strip. You can expect a result in 15 minutes. But in the case of a false-negative test result, that is, the patient is asymptomatic but has an infection, the rapid antigen test is not reliable.
Another study found that antigen tests are more specific when a person already presents with symptoms. While many studies show that antigen tests have a low sensitivity compared with PCR tests, further research states they have a high specificity or can detect people who do not have the disease correctly. Since lateral flow tests do not amplify the material they are looking for, the sample needs to contain enough viral antigen for the test to detect it. This makes it less accurate and shows a false-negative result in the early stages of infection when a person is asymptomatic and after the acute phase of the disease when the viral load decreases.
The Food and Drug Administration also warned healthcare professionals that false-positive results might occur in antigen tests, especially when users do not follow the instructions. A Canadian study found that around 0. On the other hand, the CDC state that PCR tests may render positive results weeks to months after the initial infection. A person who shows symptoms should take a test immediately. A person who does not show symptoms but has had close contact with someone with COVID should take a test at least five days after exposure.
A person who needs urgent results or is currently experiencing symptoms may take an antigen test to get an immediate result. However, an antigen test may not provide an accurate result for people who are not experiencing symptoms.
People who have had exposure to the virus, or have been in high-risk areas, who need to undergo a medical procedure, or continue to have symptoms even with a negative antigen test, should take a PCR test.
An antigen test can also be helpful for people in isolation who want to check if they are still infectious. A person can buy antigen tests in local pharmacies and some online stores. PCR tests are only available in centers, facilities, and hospitals. People can check their state health departments or local health departments for health centers and community-based testing sites that offer these tests for free.
Healthcare professionals can obtain samples from the nose, throat, or mouth saliva. There are three methods for collecting a sample through a nasal swab:.
Other methods include collecting saliva into a sterile cap container or inserting a long swab at the back of the throat oropharyngeal to collect a sample.
It may show one of the following results:. In an antigen test, two lines mean that the test detects the virus in the sample, while a single line in the control line indicates that the virus is not in the specimen. PCR and antigen tests have their advantages and disadvantages.
They differ in their procedure, accuracy, results, timing, skill requirement, price, and availability. However, antigen tests are also accurate and specific when a person already has symptoms.
Antigen tests are affordable and may be helpful in situations such as when a person needs serial testing, wants to know if they are still infectious, or needs quick results.
