COVID-19 is a sickness caused by a virus. The virus is called SARS-CoV-2.
We have different ways to check if someone has this virus. One way is to use a test you can do at home. It’s called a rapid antigen test.
COVID-19 Testing: An Overview
When you feel sick or think you’ve been around someone with COVID-19, you might want to get tested.
A test can tell you if you have the virus. Some tests are done at a hospital or clinic. But others, like the rapid antigen test, can be done at home.
What Is the Rapid Antigen Test?
The rapid antigen test is a quick and easy way to check for COVID-19. It looks for parts of the virus in your body. You take a swab from your nose or throat and put it on a small test strip.
Then you wait for a few minutes. If a line shows up on the strip, you might have the virus.
The Study: Understanding the Rapid Antigen Test
Scientists wanted to know how good the rapid test is. They’re from the University of Massachusetts Chan Medical School.
They worked with more than 5,000 people who didn’t seem sick. These folks did the rapid test at home on the first day.
Then they did a different test and sent it to a lab. The other test is called an RT-PCR test. It’s more accurate but takes longer to get results.
The Findings: When Should You Test?
The scientists found that the rapid test works best when you do it more than once. If you don’t feel sick, you should do the test three times.
Wait two days between each test. If you feel sick, you should do it two times with the same waiting period.
It’s also important to know that the rapid test rarely says you’re sick when you’re not. This is called a false positive. So, if your rapid test is positive, you probably have the virus. You don’t need to test again.
What Does This Mean for You?
These findings tell us something important. If you think you might have COVID-19, don’t just do one test. Do several tests, two days apart. This gives you the best chance to know if you have the virus.
Also, keep doing things to stay safe. Even if your first test is negative, keep wearing a mask and staying away from others until you know for sure. The rapid test is a good tool, but it’s not perfect. We still need to be careful.
Wrapping It Up
Testing for COVID-19 is important. It helps us know who has the virus. This can help stop the spread of the disease.
But, it’s also important to remember that no test is perfect. We need to use them correctly and keep being careful.
The study from the University of Massachusetts Chan Medical School gives us useful information. It helps us know how to use the rapid antigen test better.
But we also need to keep learning. As we get more information, we can make better decisions about our health.
If you care about COVID, please read studies about new evidence on rare blood clots after COVID-19 vaccination, and how diets could help manage post-COVID syndrome.
For more information about COVID, please see recent studies that low-sodium plant-based diets may prevent COVID-19 better, and results showing extracts from two wild plants can inhibit the COVID-19 virus.
The study was published in the Annals of Internal Medicine. Follow us on Twitter for more articles about this topic.
