2. Testing Tips: Rapid and PCR tests – which one should you take and when?
There are two main types of COVID-19 diagnostic testing: antigen (rapid) and PCR tests. Both tests tell you whether or not you currently have a COVID-19 infection; however, there are some key differences:
| PCR test | Antigen (Rapid) test | |
|---|---|---|
| What is being tested? | Whether someone currently has an active COVID-19 infection.This test detects genetic material of COVID-19. | Whether someone currently has an active COVID-19 infection. This test detects proteins that are associated with COVID-19. |
| How long does it usually take to get results? *due to current high demand of testing, results may take longer than expected |
A few days It takes a bit longer due to the process which requires extracting the genetic material of the virus and then replicating it to levels high enough for detection. |
A few minutes to a few hours This doesn’t take that long because it directly detects the viral proteins that are on the swab. |
One question many people have is: which test should I take and when? If testing is available and accessible to you, the table below may be helpful to determine which test is best to take if you are exposed to and/or subsequently develop COVID-19.
Which type of COVID-19 test should I use when?
- Following an exposure, to diagnose a COVID-19 infection
- A PCR test is best used to determine whether someone has COVID-19, at least three days after an exposure to someone who tested positive for the virus.
This test is good because it can detect very small amounts of the virus’s genetic material and test positive even before symptoms occur.Rapid antigen tests, if administered correctly, can still tell you if you currently have a COVID-19 infection, but they are not as sensitive to small amounts of the virus. Therefore, rapid tests may not detect an early COVID-19 infection when there is in fact one. If you are using a rapid antigen test after an exposure, it is best to test yourself several times on subsequent days, especially if you have symptoms.
- A PCR test is best used to determine whether someone has COVID-19, at least three days after an exposure to someone who tested positive for the virus.
- After a COVID-19 infection to determine if you are still infectious
- A rapid test is the best test to determine if you are still infectious after the isolation period of a COVID-19 infection.
PCR tests are less desirable for this reason because this type of test can still detect a small amount of the virus (including dead, noninfectious, versions of the virus) for weeks or months following an initial infection. This means that after a COVID-19 infection, a PCR test may still have a positive result, when you are no longer contagious to others.
Antigen tests are good if you need to make an informed decision about whether to attend work or school and cannot get a PCR test.
All at home tests that do not require a mail-in are antigen tests.
- A rapid test is the best test to determine if you are still infectious after the isolation period of a COVID-19 infection.
