The Biden administration recently announced that it is making four more COVID-19 antigen tests, also known as rapid tests, available to each U.S. household for the fall of 2023. You can order your tests through the federal government’s COVID.gov website.
A positive result on one of these tests is a reliable indication that you have COVID-19, especially when you are also experiencing symptoms like fever, cough, or shortness of breath, says Bernard Camins, MD, Medical Director of Infection Prevention for the Mount Sinai Health System.
Dr. Camins says that if you test positive and have symptoms, you should schedule a follow-up virtual or in-person visit with a health care provider, especially if you are at high risk for complications. The provider can prescribe an antiviral medication like Paxlovid™ (nirmatrelvir/ritonavir), which can help if taken within five days after your symptoms begin. The medicine works by stopping the virus from multiplying in the body.
(The Centers for Disease Control and Prevention (CDC) also recommends that if you test positive, you isolate from other people for five days or until your symptoms improve, whichever is longer. If you need to be around other people during this time, wear a high-quality mask.)
A negative rapid test does not necessarily mean that you do not have COVID-19, Dr. Camins says. Especially if you have symptoms, a negative test may just mean it was too early to detect the virus.
The Food and Drug Administration (FDA) recommends that people who have COVID-19 symptoms and test negative on a rapid test take another test 48 hours later. If you were exposed to COVID-19 but do not have symptoms, the FDA recommends that you test three times, with 48 hours between each test.
You can also take a laboratory test called a polymerase chain reaction (PCR) test, which is more reliable than a rapid test but must be given at a medical office. Mount Sinai Health System offers several ways to get a PCR test in the New York metropolitan region:
- If you do not have any symptoms but need a test, contact your primary care provider or find a test site near you.
- If you need a test due to mild symptoms, our Mount Sinai Urgent Care locations throughout New York City accept both walk-in and scheduled appointments 365 days a year.
- Please wear a mask and practice social distancing. It is especially important to wear a face mask on the way to your appointment to help prevent the spread of any respiratory virus you may have.
