Gone are the days when Hollywood stars and the well-connected were among those who could get rapidly tested for the coronavirus. After the Food and Drug Administration approved the first at-home diagnostic coronavirus test more than a year ago for emergency use, buying COVID-19 tests online and over the counter has become commonplace — so long as the hot commodity is in stock.

Coronavirus testing appointments and at-home test kits are in high demand following the busy holiday season of back-to-back gatherings and the Omicron surge, which has caused event cancellations and temporary shutterings of movie theaters and other businesses. Cities including Los Angeles this week launched take-home PCR test kit programs, and President Joe Biden announced in a COVID-19 briefing Thursday, Jan. 13, that his administration will launch a website next week that will allow Americans to order free tests to be shipped to their homes, though the date and URL have yet to be provided. The government is also providing five million free PCR tests to schools per month and increasing the number of free tests to one billion.

Antigen Versus PCR Versus Antibody COVID-19 Tests: What’s the Difference?

There are two types of COVID-19 tests: diagnostic tests, which can be done at home and at local testing sites; and antibody tests, which requires a prescription from a health care provider.

Per the FDA, there are two types of diagnostics tests used to detect an active COVID-19 infection from specimens collected with a nasal or throat swab or saliva collected into a tube: molecular (RT-PCR or PCR) tests and antigen tests (also called rapid diagnostic tests).

The main difference between the two is that antigen tests “detect specific proteins on the surface of the coronavirus,” and you can get results in as little as 10 to 45 minutes. Molecular tests (PCR) detect viral RNA and it may take up to several days to receive results after tests are processed in a lab, according to Harvard Health.

The prescription-only antibody tests are not used to diagnose an active coronavirus infection. Instead, they “look for antibodies in your immune system produced in response to SARS-CoV-2, the virus that causes COVID-19,” says the FDA. A blood sample is needed for an antibody test and it must be administered by a doctor or another medical professional.

Are At-Home COVID-19 Test Kits Covered by Insurance?

Yes, COVID-19 tests are covered by insurance. The White House is requiring that private health insurance companies cover the cost of over-the-counter diagnostic tests starting Saturday, Jan. 15.

COVID-19 Testing Update: Today, our administration announced that beginning January 15, 2022, individuals covered by a health insurance plan who purchase an FDA-approved, over-the-counter COVID-19 diagnostic test will be able to have those tests covered by their insurance.

Are At-Home COVID-19 Tests Effective?

As the New York Times points out, “no medical test is perfect [and] there has always been a risk of a false positive or a false negative result” when test-takers don’t properly follow directions. Most COVID-19 tests are “generally accurate when used correctly but in some cases can appear to show a positive result when exposed to other liquids,” the newspaper reports.

Health experts say that PCR tests are the most accurate option as they require a lab to process specimens, according to Harvard Health. Over-the-counter COVID-19 tests (often called at-home or DTC tests) “tend to be less accurate,” but they’re still helpful “when quick results are needed or for general screening and surveillance,” the university says.

However, the FDA recently alerted consumers to stop using tests that don’t meet accuracy standards, including LuSys Laboratories’ COVID-19 antigen and antibody tests, both of which, the agency says, have “a high risk of false results.”

Where to Buy COVID-19 Tests Online

When leaving the house isn’t an option, or you prefer to keep a backup stock of testing kits at home, ordering COVID-19 tests online is another route. Tests approved by the FDA for emergency use are available in stores and online at authorized pharmacies and retailers, and the government agency warns against buying COVID-19 tests from sellers on Craigslist, Facebook Marketplace and other online marketplaces to avoid potentially fake products. The FDA has a full list of fraudulent coronavirus tests and treatments on its website, and the Federal Trade Commission recommends researching the company or brand name and looking at reviews before buying tests at an unfamiliar website.

Below, we’ve gathered a handful of authorized retailers that offer at-home antigen and PCR testing kits online for shipping or in-store pickup, including Amazon, CVS, Everlywell, Gopuff, Walgreens and Walmart.
