Are Rapid COVID-19 Test Results Reliable

[Michael Catudal]

COVID-19 is a respiratory disease that can cause severe illness, especially in people with preexisting health conditions like diabetes, obesity, and high blood pressure.Two types of tests are commonly used to test for current infection of SARS-CoV-2, the coronavirus that causes COVID-19.The first type are polymerase chain reaction (PCR) tests, also called a diagnostic tests or molecular tests. These can help diagnose COVID-19 by detecting genetic material of the coronavirus. PCR tests are considered the gold standard for diagnosis by the Centers for Disease Control and Prevention (CDC)

[Michael Catudal]

The second type are antigen tests. These help diagnose COVID-19 by searching for certain molecules found on the surface of the SARS-CoV-2 virus.Rapid tests are COVID-19 tests that can provide results in as little as 15 minutesTrusted Source and don’t require lab analysis. These usually take the form of antigen tests.Although rapid tests can provide quick results, they aren’t as accurate as PCR tests analyzed in a lab. Keep reading to learn how accurate rapid tests are and when they’re used instead of PCR tests.Rapid COVID-19 tests often provide results within minutes and don’t need to be analyzed in a laboratory by a specialist.Most rapid tests are antigen tests, and sometimes the two terms are used interchangeably. The CDCTrusted Source stopped using the term “rapid” to describe antigen tests, though, because the FDA has also approved laboratory-based antigen tests.

During the test, you or a medical professional will insert a cotton swab into your nose, throat, or both to collect mucus and cells. Your sample is then usually applied to a strip that changes color if you test positive for COVID-19.Although these tests provide quick results, they aren’t as accurate as laboratory tests because they require more of the virus in your sample to report a positive result. Rapid tests come with a high risk of giving a false negative result.A false negative means the test shows you don’t have COVID-19 when you do actually have it.A March 2021 review of studies examined the results of 64 test accuracy studies evaluating commercially produced rapid antigen or molecular tests.The researchers found that the accuracy of the tests varied considerably. Here’s a look at their findings.For people with symptoms of COVID-19, the tests correctly gave a positive result an average of 72 percent of the time. The 95 percent confidence intervals were 63.7 to 79 percent, meaning that the researchers were 95 percent confident that the average fell between these two values.

The 95 percent confidence intervals were 63.7 to 79 percent, meaning that the researchers were 95 percent confident that the average fell between these two values.

The researchers found that people without COVID-19 symptoms correctly tested positive in 58.1 percent of rapid tests. The 95 percent confidence intervals were 40.2 to 74.1 percent.Rapid tests more accurately provided a positive COVID-19 result when administered during the first week of symptoms. The researchers found that rapid tests correctly identified COVID-19 in an average of 78.3 percent of cases during the first week.In the second week, the average dropped to 51 percent.The researchers found a large range of accuracies between manufacturers of the tests.

Coris Bioconcept scored the poorest and correctly provided a positive COVID-19 result in only 34.1 percent of cases. SD Biosensor STANDARD Q had the highest score and correctly identified a positive COVID-19 result in 88.1 percent of people.In another studyTrusted Source published in April 2021, researchers compared the accuracy of four types of COVID-19 rapid antigen tests. The researchers found that all four tests correctly identified a positive COVID-19 case about half the time and correctly identified a negative COVID-19 case almost all the time.Rapid tests rarely give a false positive result. A false positive is when you test positive for COVID-19 when you don’t actually have it.In the March 2021 review of studies mentioned earlier, the researcher found that rapid tests correctly gave a positive COVID-19 result in 99.6 percent of people.Many airports, arenas, theme parks, and other crowded areas provide rapid COVID-19 testing to screen for potential positive cases. Rapid tests won’t catch every COVID-19 case, but they can catch at least some cases that would have otherwise gone unnoticed.

Antibody tests look for proteins made by your immune system, called antibodies, that suggest past coronavirus infection. Specifically, they look for antibodies called IgM and IgG. Antibody tests can’t diagnosis current coronavirus infection.The January 2021 study found that an IgM and IgG antibody tests correctly identified the presence of these antibodies in 84.5 and 91.6 percent of cases, respectively.If you think you have COVID-19, you should isolate yourself from others as soon as possible. The CDCTrusted Source continues to recommend a 14-day quarantine unless you’re fully vaccinated against the coronavirus or had a positive COVID-19 result within the past 3 months.However, your local public health department may recommend a 10-day quarantine or a 7-day quarantine if you have a negative test result on day 5 or later.

Order Panodyne COVID-19 test in a pack of 1 or 24 pieces at the best online price. The Panodyne COVID-19 test is an antigen rapid test kit (nasopharyngeal swab/oropharyngeal swab) which has gained CE certification is intended to help identify whether (at the time of testing) you have COVID-19 (Coronavirus).
