Rapid antigen tests are less accurate than molecular tests, so your doctor may recommend a molecular test when your antigen test result does not make sense with your symptoms and exposure history. For example, when the antigen test says you are infected but you do not have symptoms (and have not been exposed recently). Another example is when your antigen test says you are not infected but you have symptoms. Rapid antigen tests have their best accuracy within 7 days of symptoms starting. Accuracy and the clinical significance of results beyond the 7 days is not known.

How to get the test

Check if you’re eligible for a $0 out-of-pocket test and schedule an appointment at a Quest Patient Service Center.

Moving forward faster

Rapid antigen testing may be helpful for those who want quick results to meet a testing requirement for an event or travel. For example, this test can be used if you plan to visit a location or establishment that requires testing prior to arrival. Testing requirements vary by location and may change over time.

Regardless of your test result, you should discuss your results with your doctor and continue to follow any safety precautions recommended by public health experts. This can help you and your community better manage the risks and benefits of resuming daily activities.
