If you’re using at-home antigen tests, it’s recommended that you test multiple times over the course of a few days. So, timing is essential when using rapid tests. This is more likely to happen if you test too early when there’s not enough virus for the test to detect. That means you’re infected with the virus, but you’ve tested negative. However, you may be more likely to get a false negative result with a rapid test. This has been found to be the case with Omicron variant infections, too. If you get a positive result from a rapid test, there’s a good chance you’re infected with SARS-CoV-2. So, you may be wondering how rapid diagnostic tests stack up. Standard molecular tests are the gold standard (most accurate option) for COVID-19 testing. Antigen tests typically take about 15 minutes to get results. Several are available OTC, including BinaxNOW by Abbott. Many antigen tests have also been authorized for use at point-of-care or at home. These tests tend to be simpler in design and less expensive than molecular tests. Antigen testsĪntigen tests look for specific proteins on the surface of the virus. They deliver results in 30 minutes to an hour. Most of these tests can produce results in 30 minutes or less.ĭetect and Lucira are two OTC rapid molecular tests that you can perform entirely at home. These include several that can also test for other viruses, like those that cause the flu. Many rapid molecular tests have been authorized for use at point-of-care. Genetic material from the sample is copied and compared to the genetic sequence of the virus. These tests most often use techniques called RT-PCR (reverse transcription polymerase chain reaction) or isothermal amplification. They were the first type of COVID-19 test to be authorized and widely used. Molecular tests detect the presence of viral genetic material in a sample. The FDA has also authorized a rapid COVID-19 breath test, but it’s not widely available yet. They work differently in how they detect SARS-CoV-2, the virus that causes COVID-19. There are currently two different types of rapid diagnostic tests available: molecular and antigen tests. These tests can be done entirely from the comfort of your home. What’s more, many rapid tests are available over the counter (OTC). They often use a portable device to test samples, so the entire process can be completed at the same place. And they don’t require an outside laboratory for processing samples. Rapid tests can also be done at point-of-care (e.g., testing site, provider office). In general, most rapid tests provide results in 15 to 30 minutes. The fastest test currently available, ID NOW by Abbott, can detect the virus in 13 minutes or less. This allows them to process samples faster. Compared to standard molecular tests, rapid tests are often simpler. The key difference between rapid tests and standard molecular tests is how long they take to process results.Īs the name suggests, rapid tests can produce fast results. Here, we’ll cover some testing basics and where you can find rapid testing near you. Rapid COVID-19 tests are available at community-based testing sites, provider offices, and even the shelves of your local pharmacy or supermarket. But the emergence of rapid testing has helped remove some of the roadblocks for faster results. Early on, it would sometimes take days to weeks to get your results. At-home COVID test kit manufacturers Abbott BinaxNOW and QuickVue did not immediately respond to Nexstar’s request for comment.Since the start of the COVID-19 pandemic, over 1 billion COVID-19 tests have been performed in the U.S. Statements regarding their own at-home COVID test supplies from Target and Kroger were not available at the time of publication. Additionally, each store may set its own limits based on local inventory. Customers are limited to eight testing kits per online order. “We’re committed to providing families with protection and peace of mind during the holiday season, and we continue to offer access to lab-based testing with results available in 1-2 days or rapid COVID-19 testing at more than 4,800 CVS Pharmacy locations.”Ī Walmart spokesperson says they are also seeing an “extremely high demand on Covid-19 at home testing kits.” While inventory levels at its stores are “strong,” inventory is limited for its online division. Due to a recent surge in demand, and to retain community-based access to tests in our stores, there may be temporary out-of-stocks for these products on CVS.com,” the statement continues. “To ensure equitable access to tests both in store and digitally, we’ve added a limit of six test kits per purchase.
