Why Some Rapid Antigen Tests May Miss New and Emerging Strains


With the new and emerging strains of the coronavirus, there is a new level of urgency to get rapid antigen tests that can detect these variants. However, not all rapid antigen tests are made equal. Some may miss new and emerging strains. It’s important to be aware of this so you can make sure you are getting a rapid antigen test that can detect the new and emerging strains. Keep reading to learn more about why some rapid antigen tests may miss new and emerging strains.

  1. How do rapid antigen tests actually work?

If you’ve been paying attention to the news lately, you’ve probably heard a lot about rapid antigen tests. These are becoming the easiest test for the presence of a virus, such as the flu or COVID-19. But how do they actually work?

Rapid antigen tests work by bind to specific proteins that are found on the surface of a virus. This binding process produces a signal that can be detected by the test. If the test detects this signal, it means that the virus is present.

One of the advantages of rapid antigen tests is that they can be performed quickly and easily. However, there are also some disadvantages. Rapid antigen tests are not as accurate as other types of tests, such as PCR tests. This means that they may sometimes produce false positive or false negative results.

  1. Why do some antigen tests miss new and emerging strains?

So, antigen tests are not perfect. In fact, they can sometimes miss new and emerging strains of the virus. So why do these tests sometimes fail?

There are a few reasons why antigen tests might miss a new strain of the virus. First, the test might not be sensitive enough to detect the new strain. Second, the new strain might not be widespread enough to be detected by the test. And third, the new strain might be so new that there isn’t enough data on it yet to create a reliable test.

So if you’re using an antigen test, remember that it can’t always detect every strain of the virus. It’s important to stay updated on the latest research and virus mutations in order to get a true picture of your health and wellness. We can now also test for Influenza A and B with a Combo Rapid Test.

Alpha, Beta, Gamma, Delta, Kappa, Epsilon, Iota, Omicron, BA.4, BA.5 ……..

  1. What does this mean for us?

The recent news that some rapid antigen tests may miss new and emerging strains of the virus is concerning. This means that people who think they are negative may still be able to spread the virus.

This is a big problem for us because it means that we can’t rely on these tests to keep us safe. We need to be extra careful to make sure that we’re not exposing ourselves to the virus. We should continue to wear masks, social distance, and wash our hands often.

The best thing anyone can do is check to see which strains are covered by which tests.

  1. So…which tests don’t cover all strains?

Unfortunately, no test is 100% accurate all of the time. As the season progresses and new strains emerge, the accuracy of tests may change. That’s why it’s important to stay up-to-date on the latest information about which tests are most accurate. HERE


Some Rapid antigen tests may miss new and emerging strains for a variety of reasons. First, these tests are not as sensitive as other types of tests, so they may miss some infections. Second, the tests may not be able to detect new strains that have not been seen before. Finally, the tests may not be able to distinguish between new and emerging strains and other strains that are already circulating. To make sure the Rapid Tests you have are accurate, it is important to make sure they are up to date with the latest information on the new and emerging strains.
