What Does This Test Measure?

The test looks for the unique genetic sequence of the SARS-CoV-2 virus in your sample. This sequence is used to confirm whether the virus is present and to understand its genetic characteristics, which can sometimes help track virus variants.

How Is the Sample Collected?

A small amount of your bodily fluid (such as nasal or throat swab, saliva, or respiratory secretions) is collected and sent to the lab. The lab then extracts the virus’s genetic material (nucleic acids) from the sample for testing.

Why Might This Test Be Ordered?

Your healthcare provider may order this test if you have symptoms of COVID-19, have been exposed to someone with COVID-19, or if you are required for testing in a clinical or research setting. It can also help monitor the progression of infection or guide treatment decisions.

What Are the Possible Results?

A positive result means the virus’s genetic material is detected, indicating an active COVID-19 infection. A negative result means the virus’s genetic material was not found in the sample, though this does not always mean you are not infected (false negatives can occur).

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How soon can I expect results?
Results typically take 24 to 72 hours, depending on lab processing times and your healthcare provider’s workflow. Follow-up instructions from your provider will outline next steps if your result is positive or negative.
What does a positive result mean?
A positive result confirms the presence of the SARS-CoV-2 virus in your sample, meaning you likely have an active COVID-19 infection. Your provider will guide you on next steps, such as isolation, treatment, or further testing.
Can I get this test at home?
Some testing sites offer at-home collection kits for this test, where you may collect a sample (such as a nasal swab or saliva) at home and send it to a lab. Always follow the instructions provided with your kit to ensure accurate results.
