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. Since the start of the COVID-19 pandemic, over 1 billion COVID-19 tests have been performed in the U.S.
