There are two main types of tests used to diagnose an active COVID-19 infection:
1. Viral tests: These tests detect the presence of the SARS-CoV-2 virus, which causes COVID-19. There are two main types of viral tests:
- Polymerase Chain Reaction (PCR) tests: These are the most accurate and reliable tests for detecting active infection. They work by detecting the genetic material of the virus. Results typically take several hours to days.
b
- Antigen tests: These tests are faster and more convenient than PCR tests, providing results in 15-30 minutes. However, they are slightly less accurate, especially when you have no symptoms. It's recommended to repeat negative antigen tests at least once, 48 hours apart, to be more confident in the result. You can even use self-tests (at-home tests) as antigen tests.
2. Choosing the right test:
The best test for you depends on several factors, such as:
- Your symptoms: If you have symptoms suggestive of COVID-19, a PCR test is generally recommended for the most accurate diagnosis.
b
- Your need for speed: If you need results quickly, an antigen test may be a good option. However, be aware of the potential for inaccurate results, especially if you have no symptoms.
- Your situation: If you are in a high-risk setting or need confirmation of a negative antigen test, a PCR test might be preferred.
Here are some additional things to keep in mind:
- It's crucial to follow the specific instructions for the test you choose, whether conducted by a healthcare professional or self-administered at home.
b
- Regardless of the test result, it's essential to follow public health guidelines, such as isolation and masking, if you have symptoms or test positive.
- If you have questions or concerns about testing, consult your healthcare provider.
