These at-home OTC COVID-19 diagnostic tests are FDA authorized for self-testing at home (or in other locations) without a prescription. Tests are available online or at local stores and you collect your own sample, perform the test, and read the result yourself without the need to send a sample to a laboratory.
With most at-home OTC COVID-19 diagnostic tests, you should repeat testing following a negative result, whether you have symptoms or not, to reduce your risk of a false negative test result. The FDA encourages you to voluntarily and anonymously report your positive or negative test results every time you use an at-home COVID-19 test. You can send your test result to MakeMyTestCount.org or use an app or other digital option for self-reporting that may be included with your test. For additional information on reading and understanding your test results, see Understanding At-Home OTC COVID-19 Antigen Diagnostic Test Results.
The table below is updated regularly and lists FDA-authorized at-home OTC COVID-19 diagnostic tests, including information on expiration dates, who can use the test, links to home use instructions for each test, and other details that may help you decide what test is right for you. For additional information about each Emergency Use Authorization (EUA), see In Vitro Diagnostics EUAs: Tables of IVD EUAs.
In the table below, the "Expiration Date" column lists where to find the expiration date for that test, and the "Other Details" column lists the shelf-life for the test. The shelf-life is how long the test should work as expected and is measured from the date the test was manufactured. The expiration date is set at the end of the shelf-life and is the date through which the test is expected to perform as accurately as when manufactured. In some cases, the expiration date for a test may be extended.
An extended expiration date means the manufacturer provided data showing that the shelf-life is longer than was known when the test was first authorized. For more information about how the expiration date is determined and why it may be extended, see the At-Home COVID-19 Diagnostic Tests: Frequently Asked Questions.
In 2018 Microsoft released the Diagnostic Data Viewer (DDV) which is a tool that lets you review the raw diagnostic data Windows is sending to Microsoft. Now you can also view Office diagnostic data using the same viewer. The DDV requires Windows 10, version 1803 or newer. Viewing diagnostic data from Office requires Microsoft 365, or Office 2019, for Windows, version 1904 or newer; or Microsoft 365, or Office 2019, for Mac, version 16.28 or newer.
The Diagnostic Data Viewer (DDV) has been able to show you the Windows diagnostic data, and on Windows and Mac we've now enabled it to show you Office diagnostic data as well. We'll get into the details in a moment, but basically what you do is start the DDV in Windows, then go to any compatible Office desktop application - such as Word, Excel, or PowerPoint - and turn on diagnostic data viewing. When you return to the DDV you'll see Office diagnostic data in addition to the Windows diagnostic data.
Select Enable data viewing, and then enter the connection string for a different Windows device (on the same network) that is running the Diagnostic Data Viewer. You can find the connection string in the Diagnostic Data Viewer settings on the other Windows device.
Within a few minutes you should start seeing diagnostic data from Office in the Diagnostic Data Viewer. You only need to turn diagnostic data viewing on (or off) in one application. That turns diagnostic data viewing on (or off) for all supported Office applications on the device at the same time.
If you're trying to view diagnostic data on a device other than the device it's being collected from (for example, viewing diagnostic data for your Mac from a device running Windows), the two devices have to be on the same network. Also, only private network IP address ranges, as defined in RFC 5753, are supported. For example, 10.0.0.x., 172.16.0.x, or 192.168.0.x.
If any diagnostic data is generated at the very end of a session, Office will cache that data and upload it at the start of the next session. That means in some instances you may see data from the end of the previous session appear at the start of a new session. It also means that you may not see the very last bits of data from a session until you restart the app to launch a new session.
You expect Microsoft 365 to be secure and work properly. To meet this expectation, we collect diagnostic data as you use Microsoft 365 and OneDrive which helps us find and fix problems, identify and mitigate threats, and improve your experience. This data doesn't include your name or email address, the content of your files, or information about apps unrelated to Microsoft 365 or OneDrive.
Required diagnostic data is the minimum amount of data that we need to collect in order to keep the product secure, up to date, and performing as expected. For example, if a Microsoft 365 application crashes, certain details about the crash, that help us to diagnose and fix the problem, are collected.
On the Mac the Microsoft Automatic Update is one example of a service that has to collect required data in order to keep the installed Microsoft software -- such as Edge, Defender, Intune, Skype for Business or Remote Desktop -- up-to-date. For example, if a software update didn't complete successfully we need to be able to troubleshoot that issue.
Optional diagnostic data is data you can choose to provide, this data helps us make product improvements and provides enhanced information to help us diagnose and fix issues. For example, learning how long it takes a thumbnail version of a PowerPoint slide to render so we can improve the performance of that feature.
The Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit provides comprehensive and preventive health care services for children under age 21 who are enrolled in Medicaid. EPSDT is key to ensuring that children and adolescents receive appropriate preventive, dental, mental health and specialty services.
States are required to furnish all 1905(a) Medicaid coverable, appropriate, and medically necessary services needed to correct and ameliorate health conditions, based on certain federal guidelines. EPSDT is made up of the following screening, diagnostic, and treatment services:
At a minimum, vision and hearing services include screening, diagnosis and treatment for defects in vision and hearing such as hearing aids and eyeglasses. Vision services must be provided according to a periodicity schedule and at other intervals as medically necessary. For additional information visit the Vision and Hearing Screening Services for Children & Adolescents page.
Covered dental services must, at a minimum, include dental care needed for relief of pain, infection, restoration of teeth, maintenance of dental health (provided at as early an age as necessary), and medically necessary orthodontic services. Each state is required to develop a dental periodicity schedule in consultation with recognized dental organizations involved in child health. Services at more frequent intervals than specified in the periodicity schedule are covered when medically necessary for an individual child. Refer to the Dental page for more information.
All children under age 21 eligible for EPSDT should receive all age-appropriate vaccines as recommended by the Advisory Committee on Immunization Practices. The VFC program provides federally purchased vaccines to children who are enrolled in Medicaid, uninsured, underinsured, or American Indian/Alaska Native. Additional information is available on the Quality of Care Vaccines page.
States are required to provide any additional 1905(a) services that are coverable under the Federal Medicaid program and found to be medically necessary to treat, correct, or reduce illnesses and conditions discovered regardless of whether the service is covered in a state's Medicaid plan. It is the responsibility of states to determine medical necessity on a case-by-case basis.
When a screening examination indicates the need for further evaluation of an individual's health, diagnostic services must be provided. Necessary referrals should be made without delay and there should be follow-up to ensure the enrollee receives a complete diagnostic evaluation. States should develop quality assurance procedures to assure that comprehensive care is provided.
CMS developed a set of strategy guides to support states and their partners as they implement the EPSDT benefit. Each strategy guide identifies specific, doable approaches to improve access, utilization and quality of care for children and adolescents enrolled in Medicaid. Examples of state successes are offered along with web-based links to resources, tools and more in-depth information.
Fully accredited by the American Association of Veterinary Laboratory Diagnosticians, the VDL provides quality diagnostic services for animal species, including necropsy, bacteriology, serology, histopathology, virology, parasitology, molecular diagnostics, and toxicology as well as offering analytical services.
For symptomatic persons with dengue virus infection, dengue virus RNA can usually be detected by molecular tests for the first 0-7 days in the course of illness. After day 7, molecular tests may not be as sensitive.
NS1 is detectable during the acute phase of dengue virus infections. NS1 tests can be as sensitive as molecular tests during the first 0-7 days of symptoms. After day 7, NS1 tests may not be as sensitive.
IgM antibody testing can identify most recent dengue infections after day 3 of illness. These tests should be run on samples with negative NS1 and PCR results, particularly after day 3 of illness. Interpreting positive IgM results is complicated because of cross-reactivity with other flaviviruses, like Zika.
