The Forbes Health editorial team is independent and objective. To help support our reporting work, and to continue our ability to provide this content for free to our readers, we receive compensation from the companies that advertise on the Forbes Health site. This compensation comes from two main sources. First, we provide paid placements to advertisers to present their offers. The compensation we receive for those placements affects how and where advertisers’ offers appear on the site. This site does not include all companies or products available within the market. Second, we also include links to advertisers’ offers in some of our articles; these “affiliate links” may generate income for our site when you click on them.

The compensation we receive from advertisers does not influence the recommendations or advice our editorial team provides in our articles or otherwise impact any of the editorial content on Forbes Health. While we work hard to provide accurate and up-to-date information that we think you will find relevant, Forbes Health does not and cannot guarantee that any information provided is complete and makes no representations or warranties in connection thereto, nor to the accuracy or applicability thereof.

Despite the recent ease of COVID-19 restrictions, nearly half of U.S. adults (47%) say they took an at-home COVID-19 test at some point in the past three months after feeling sick, according to new data from the Forbes Health-Ipsos Monthly Health Tracker survey.

Additionally, of the 1,120 U.S. adults polled between August 16 and 17, 65% stayed home or away from people they don’t live with if they felt ill, 44% isolated from people inside their household and 27% took a PCR COVID-19 test from a doctor or testing site. (Respondents could choose multiple answers.)

If you’re experiencing COVID-19 symptoms, such as a cough, fever or chills, or just want peace of mind when traveling and gathering with others, there are many testing avenues available.

Experts suggest it’s still a smart move to take the appropriate health measures if you think you were exposed to the COVID-19 virus. Regardless of vaccination status, the Centers for Disease Control and Prevention (CDC) recommends masking up immediately. From there, watch for symptoms—such as a fever, cough or shortness of breath—and if they develop, the CDC recommends getting tested and isolating immediately. Even if you don’t experience symptoms, the CDC recommends testing five days after exposure.

There are a couple types of COVID-19 tests: PCR-based tests (called nucleic acid amplification tests), which are performed in a laboratory and detect genetic material of the virus, and antigen-based tests, which are rapid tests and a good option for people who want results quickly, as they provide a diagnosis in about 15 to 30 minutes. Most at-home COVID-19 tests are antigen-based tests, and the CDC emphasizes that a single antigen-based test does not rule out infection. Instead, a negative antigen test should be followed by another test 48 hours later.

When it comes to choosing the right test for your situation, you might be wondering where to start. Shelves are littered with different types of tests, so keep the following factors in mind when shopping.

U.S. households have the ability to order a limited number of free rapid tests from COVIDTests.gov, thanks to a White House initiative to increase the availability of tests.
