Free COVID test kits website officially live: How to order and how many you can get

Some Americans are having problems ordering from COVIDtest.gov, especially if they live in an apartment or multi-family dwelling.

On Wednesday, the federal government officially launched COVIDTests.gov, the website for Americans to order free COVID test kits. Each household can request four at-home COVID-19 tests, with orders expected to ship at the end of the month. 

The site went live for beta testing on Tuesday, with many Americans able to order then. But some experienced issues, particularly when the site misidentified fellow apartment-building residents as household members and told submitters they had already ordered their kits.

The White House said tech experts are hard at work troubleshooting continuing bugs.

"This program will ensure that Americans have at-home, rapid COVID-19 tests available in the weeks and months ahead -- in addition to the number of other ways they can get tested," the administration said on Jan. 14. "The administration is quickly completing a contracting process for the unprecedented purchase of 1 billion at-home, rapid tests to distribute as part of this program."

How do I get free at-home COVID-19 tests?

Americans can now request four free tests per household online at COVIDTests.gov. The US Postal Service will deliver kits in the continental US through First-Class Package Service, starting at the end of January. Shipments to Alaska, Hawaii, US Territories and any military addresses will be sent through Priority Mail. 

According to a White House statement, the kits will typically ship within seven to 12 days of ordering.

President Biden announced on Jan. 12 the government was doubling the number of available free tests to 1 billion, and providing 5 million PCR tests for free to schools per month. 

Several states are already issuing free COVID-19 tests to residents, including Colorado, IowaConnecticutWashingtonNew JerseyMarylandOhioOregonMassachusetts and New Hampshire.

Washington, DC, is making at-home tests available for pickup at area libraries while other cities, such as New York and Boston, are distributing them to local health clinics. We'll continue to update this list as more regions announce free COVID tests.

What are the problems accessing free COVID test kits?

During Tuesday's soft launch, it appeared the site had issues recognizing some addresses, especially if a person lived in an apartment building, multi-family home or residence connected to a commercial property. That problem continued on Wednesday morning.

"I live in a multi-family home so USPS says it's already been ordered by my neighbors," a resident of Astoria, Queens, complained on Facebook. "How can I get around this?"

The Postal Service said addresses not registered as multi-unit buildings may lead to difficulties placing orders, CNBC reported. Some users have reported that adding an apartment number in the main address line, rather than in the section for apartment number, enabled them to order.

White House press secretary Jen Psaki said IT experts with the White House and USPS "are working hard to make this a success."

"Every website launch, in our view, comes with risk," she told reporters on Tuesday. "We can't guarantee there won't be a bug or two."

The USPS also has launched a site for ordering COVID kits. According to the service, those still having trouble placing orders should file a service request online or call 800-ASK-USPS. 

How can I get reimbursed for COVID test kits I bought at a pharmacy?

As of Jan. 15, health insurance companies are required to reimburse Americans for eight at-home antigen tests per person a month, under a plan announced by President Biden. If an individual has been directed to undergo COVID-19 testing by their medical provider because of underlying health conditions or other factors, there is no limit on the number of tests covered.

Carriers can establish in-network pharmacies where the cost will be covered up front, and cap coverage at out-of-network retailers at $12 per test.

Though the Biden plan is not retroactive, some states -- including Vermont -- mandated that insurers start paying for at-home kits earlier.

You may also want to check with your employer, as some private companies also began offering reimbursement options for at-home tests before the Jan. 15 deadline.

Do Medicare and Medicaid cover at-home COVID test kits?

Biden's new rules on reimbursement for at-home COVID-19 tests don't currently apply to Medicaid and Medicare, although Bloomberg Government reports test kit producers are lobbying to change that. 

People with Medicare -- a free federal program for all Americans 65 and older -- who also have private health insurance can receive reimbursement from their insurer.

State Medicaid and Children's Health Insurance Program, aka CHIP, programs are currently required to cover FDA-authorized at-home COVID-19 tests without cost-sharing, according to HHS.

What if I don't have health insurance?

For those without insurance, Biden said there will be "thousands of locations" where you can pick up free COVID-19 test kits to use at home in private, rather than get swabbed in a drive-thru clinic. You can also order your free tests from the COVIDTests.gov website, though you're limited to four per household.

Those who don't have health insurance can also access free kits at community health clinics and other local sites. The Department of Health and Human Services offers a search tool for finding community-based testing sites for COVID-19.

Where can I buy at-home COVID-19 tests?

At-home rapid COVID-19 tests are usually available at pharmacies like Walgreens, Walmart and CVS, and via online retailers like Amazon. The White House is allowing insurers to establish a roster of in-network pharmacies and to cap coverage of kits bought at out-of-network retailers. Check with your insurance company to see which stores are in your network.

But the rapid spread of the omicron variant has led to a test kit shortage and forced retailers to place limits on how many you can purchase in many regions: Walgreens currently allows each customer to purchase a maximum of four at-home tests, while CVS sets its limit at six. Walmart caps online purchases to eight tests but has no limit on in-store purchases.

Rapid antigen at-home tests are out of stock in stores and online in many regions. A recent study by the Kaiser Family Foundation the first week of January found at-home COVID tests available online only 10% of the time.

As of Jan. 16, Walgreens has BinaxNow available in store at $24 for two tests. Walmart has On/Go's 10-minute self-test available on its website at $24 for two tests. Amazon currently has iHealth tests in stock at $20 for two tests. We'll continue to update as availability changes.

If your area drugstore is out of test kits, try your state or local health department, as many have started distributing free kits to residents. See the next section for more information and links to the states currently providing free at-home COVID tests.

How much do at-home COVID-19 tests cost?

Rapid antigen tests are generally much cheaper than home collection tests. Costs vary from brand to brand, but kits generally run about $10 to $25 apiece, with two tests per kit.

Both Walgreens and CVS are selling Abbott's BinaxNow and Quidel's QuickVue tests -- two of the first authorized by the FDA -- for $24 for a pack of two. Acon's FlowFlex rapid test is currently $10 for one test at both Walgreens and CVS. The On/Go kit of two rapid tests is currently selling for $25 on Amazon and $30 on Walmart.

Home collection tests, which require a nasal swab or saliva sample to be sent to a lab for analysis, cost much more than the rapid antigen tests and require a much longer waiting period to get results. But the "molecular" tests are considered far more accurate than antigen tests. CVS and Walgreens are selling Labcorp's Pixel home-collection test for $125.

The extreme shortage of kits has led some to resell them on platforms like Craigslist, eBay, Facebook, Instagram and even TikTok, often at an inflated price and with fraudulent merchandise. 

"We've received reports that unauthorized sellers are trying to profit from the pandemic by selling COVID-19 tests online," Washington Attorney General Karl Racine tweeted Jan 4. "Please beware and only buy tests through authorized retailers so you can ensure the integrity of your test." 

Facebook's parent company, Meta, told CNN Business it prohibits the sale of test kits on any of its platforms.

Should I use a rapid at-home test or get a PCR test?

The two main types of COVID-19 tests are rapid antigen tests and polymerase chain reaction tests. Antigen tests can be taken at home and return results in about 10 to 15 minutes. PCR tests are more accurate but require lab work and generally don't provide results for at least 12 hours or even up to 5 days.

Both tests typically use nasal swab samples, though some collect saliva. PCR tests administered by a professional may require a nasopharyngeal sample that involves a much deeper nostril swab. Rapid antigen tests usually require swirling a swab in the nostril less than an inch deep.

PCR tests amplify genetic material from the collected sample up to a billion times to detect even the slightest amount of COVID-19 genes, making them highly accurate. They're also more expensive, usually costing more than $100 apiece.

Rapid antigen tests simply detect the presence of COVID-19 antigens -- the substances that prompt your immune system to create antibodies -- and work much like home pregnancy tests. If your sample contains COVID-19 antigens, the thin line of SARS-CoV-2 antibodies on the test strip will change color.

Because rapid tests are simply looking for the existence of antigens, they work best when someone is symptomatic. Rapid antigen tests are less successful with early infections and asymptomatic cases. The risk of a false negative is much higher with a rapid test than a false positive.

The type of test you choose will mostly depend on your situation. Do you need results right now, and are willing to risk less accuracy? Then rapid antigen fits the bill. If you want closer to 100% accuracy and don't need instant results, the "gold standard" PCR is your best choice.

What if I test positive for COVID-19 using an at-home test?

If you take an at-home test and it's positive for COVID-19, it's recommended that you share the results with your medical provider and local health department. Methods of reporting self-tests to health departments vary wildly, though: Some have online forms, others require email and still others use phone reporting. Check your local health department website for specific info on how to report a positive result.

After receiving a positive test result, you should isolate for at least five days, and longer if you're symptomatic, according to the Centers for Disease Control and Prevention. Though the risk of false positives from rapid tests is low, most medical experts and health officials still recommend confirming a positive at-home test with a subsequent PCR test.
