With so many individuals receiving COVID-19 rapid antigen tests and boosters, it’s easy to overlook the other critical measures available for containing the COVID-19 pandemic. Testing is a critical component that should not be disregarded.
Unfortunately, misunderstandings regarding these exams are widespread, making it difficult for individuals to distinguish fact from fiction.
Here, specialists clarify many of the most prevalent COVID-19 testing misconceptions and explain how to properly administer exams.
Myth 1: You should only get a COVID-19 rapid antigen tests if you are experiencing symptoms.
The Centers for Disease Control and Prevention (CDC) advises that testing take place in a variety of circumstances. Of course, one of these instances is if you get COVID-19 symptoms, which include fever or chills, headache, nausea, and loss of taste or smell, among others, regardless of whether you have been vaccinated.
However, there are situations when testing is justified. If you have close contact with someone who has COVID-19, the CDC suggests that you should be tested promptly and again five to seven days later if you are unvaccinated, and five to seven days after exposure if you are fully vaccinated.
Attending big events and spending time in crowded indoor areas are risky activities that enhance your chances of coming into close contact with someone who has COVID-19.
If you are not vaccinated and travel inside the United States, you should be tested three to five days later and should remain at home and self-quarantine for seven full days, the CDC says. International plane travel may also need testing, regardless of vaccination status, both prior to departure and upon return.
Additionally, “I would recommend performing a rapid home rapid antigen tests if you are planning to see someone who is immunocompromised or elderly,” to avoid infecting them inadvertently, according to Thersa Sweet, PhD, MPH, an associate teaching professor of epidemiology and biostatistics at Drexel University in Philadelphia.
Myth 2: Increases in COVID-19 instances are a result of over testing.
Testing is critical for health professionals to monitor the virus’s transmission within a community, according to Gigi Kwik Gronvall, PhD, a senior scholar at the Johns Hopkins Center for Health Security and the director of the Johns Hopkins Center’s COVID-19 Testing Toolkit.
“We now have a better understanding of instances as a result of testing, but testing does not result in an increase in cases,” Dr. Gronvall explains.
While some attribute the increase of COVID-19 instances to an excessive quantity of testing, experts assert that this is not the case. Indeed, Dr. Sweet explains, “if the positive rate is large, it indicates that you are not testing enough individuals.” “All of the spikes I’ve observed recently coincide with a rise in the % positive, suggesting that the spikes represent actual increases in the virus in a community,” she continues.
Myth 3: PCR tests are usually preferable than rapid antigen tests.
There are two distinct kinds of testing available to identify COVID-19. One method is the polymerase chain reaction (PCR), which searches for evidence of the virus’s genetic material and is sensitive enough to identify infection in its early stages. These tests are accessible at designated COVID-19 testing locations, hospitals, and physician offices, with samples being submitted to a lab for analysis within one to several days.
The second major kind of diagnostic rapid antigen test is a rapid antigen test, also called a rapid antigen test, which identifies the presence of a particular molecule that indicates the existence of a current viral infection but does not directly record it, making it somewhat less reliable. Because the results are accessible immediately, this is the sort of rapid antigen test that is utilized at home.

“The best rapid antigen tests is the widely accessible rapid antigen tests,” says Melanie Swift, MD, MPH, co-chair of the Mayo Clinic’s COVID-19 Vaccine Allocation and Distribution Work Group in Rochester, Minnesota.
Due to the possibility that the rapid antigen tests can miss low levels of infection, if you have a negative result (meaning the rapid antigen tests indicates you do not have COVID-19), you should follow up with either a second antigen rapid antigen test — normally 24 to 48 hours later — or a PCR rapid antigen tests, Dr. Swift advises.
In many circumstances, she explains, rapid antigen tests are the superior alternative. Because they can be performed at home, “rapid antigen tests are an excellent alternative for those without symptoms who want to be screened before to or during travel, or who need testing as part of a surveillance program,” Swift adds.
Myth 4: Testing is quite unpleasant since the swab must penetrate your nose really deeply.
At the start of the pandemic, COVID-19 testing required the placement of a swab all the way back to the junction of your nose and the top of your throat referred to as the nasopharynx. Scientists were certain that if viral activity existed, it would be detected in this location, which is where the coronavirus replicates.
However, since many individuals are unable to bear the sensation of a swab being inserted deeply into the nasal canal, testing criteria were adjusted to include the middle portion of the nasal tube — less than an inch in — referred to as the mid-turbinate region. “This is far simpler and more pleasant,” Sweet explains. learn more about nasal structure by clicking here
Nasopharynx samples continue to be the most accurate. According to a review study published in PLoS One in July 2021, tests performed with a nasopharynx swab are 98 percent accurate, while those performed with a mid-turbinate or even more shallow swab are 82 to 88 percent reliable.
Nonetheless, the research authors conclude that the poorer sensitivity is mitigated by the capacity to test a larger number of individuals, making a shallower sample worthwhile.
Myth 5: If a box contains two fast tests, one should be used immediately and the other reserved for another time.
Fact: Several of the presently available fast COVID-19 test brands, such as Abbott BinaxNOW and Quidel QuickVue, are packed in pairs.
If one of these tests returns a negative result, you are urged to repeat it within three days, allowing sufficient time between rapid antigen tests – normally at least 24 hours and no more than 48 hours (check the instructions in your kit to verify).

This is because rapid antigen tests may provide a false negative result if they are performed too early in the course of the illness, when virus levels are too low to detect. If you actually have COVID-19, the second test should be positive.
(If any of the two tests is positive, you should contact your doctor immediately and also separate yourself from other people.)
