Diagnostic Test

These at-home OTC COVID-19 diagnostic tests are FDA authorized for self-testing at home (or in other locations). This means you collect your own sample, perform the test, and read the result yourself without the need to send a sample to a laboratory.

diagnostic test

There are two types of COVID-19 diagnostic tests, molecular and antigen, which detect different parts of the virus. Most authorized at-home OTC COVID-19 tests are antigen tests, and there are also a small number of authorized at-home OTC COVID-19 molecular tests.

When using a COVID-19 antigen diagnostic test, you should repeat testing following a negative result, whether you have symptoms or not, to reduce your risk of a false negative test result. For more information about this, read our FDA Safety Communication.

Authorized at-home OTC tests are available without a prescription and are typically available online or at local stores. Testing and other protective steps like wearing a mask and COVID-19 vaccination are important to stop the spread of COVID-19 infection.

The table below lists FDA-authorized at-home OTC COVID-19 diagnostic tests, and includes information on expiration dates, who can use the test, and other details that may help you decide what test is right for you. To see complete information on smaller screens, select the blue plus (+) button beside the test name.

The table includes links to home use instructions for each test. For more information about each test, including the Letter of Authorization and authorized labeling, see In Vitro Diagnostics EUAs: Tables of IVD EUAs.

In the table below, the "Expiration Date" column lists the shelf-life and where to find the expiration date for that 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. 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.

To see if the expiration date for your at-home OTC COVID-19 test has been extended, first find the row in the below table that matches the manufacturer and test name shown on the box label of your test.

Every time you go to a doctor with pain symptoms or an injury, chances are, your doctor will request that you undergo diagnostic testing. More than 13 billion diagnostic tests are performed every year in the United States. Diagnostic tests are used to confirm or rule out conditions and diseases.

There are over 110 diagnostic tests and procedures currently in use. They are either used in detecting disease and for monitoring its progression. Moreover, diagnostic tools and equipment are also used in guiding treatment and evaluating its effectiveness.

Diagnostic tests are either invasive and non-invasive. Invasive diagnostic testing involves puncturing the skin or entering the body. Examples are taking a blood sample, biopsies, and colonoscopies. Non-invasive diagnostic testing does not involve making a break in the skin.

Diagnostic imaging procedures are prime examples of non-invasive diagnostic testing procedures. Non-invasive diagnostic testing usually involves the use of highly advanced diagnostic equipment that create images of organs, soft tissues, and bones inside the body without having to make an incision. Non-invasive diagnostic testing tools are often used to determine if more invasive procedures are needed to make a diagnosis.

Radiography or X-ray uses radiation and radio waves to create images of the bones and organs. X-ray was the very first diagnostic imaging tool used and is still the most widely used non-invasive diagnostic procedure today. For broken bones and chest obstructions, X-rays are usually the first requested medical imaging procedure.

Independent Imaging has ACR-accredited diagnostic testing facilities, where we make the best and most advanced diagnostic testing procedures available to you. We believe in delivering patient-centered care and place your comfort and convenience above everything else.

Chromosomal microarray (CMA) is increasingly utilized for genetic testing of individuals with unexplained developmental delay/intellectual disability (DD/ID), autism spectrum disorders (ASD), or multiple congenital anomalies (MCA). Performing CMA and G-banded karyotyping on every patient substantially increases the total cost of genetic testing. The International Standard Cytogenomic Array (ISCA) Consortium held two international workshops and conducted a literature review of 33 studies, including 21,698 patients tested by CMA. We provide an evidence-based summary of clinical cytogenetic testing comparing CMA to G-banded karyotyping with respect to technical advantages and limitations, diagnostic yield for various types of chromosomal aberrations, and issues that affect test interpretation. CMA offers a much higher diagnostic yield (15%-20%) for genetic testing of individuals with unexplained DD/ID, ASD, or MCA than a G-banded karyotype ( approximately 3%, excluding Down syndrome and other recognizable chromosomal syndromes), primarily because of its higher sensitivity for submicroscopic deletions and duplications. Truly balanced rearrangements and low-level mosaicism are generally not detectable by arrays, but these are relatively infrequent causes of abnormal phenotypes in this population (

Medicare covers up to 8 over-the-counter (OTC) COVID-19 tests from any participating pharmacy or health care provider for each calendar month until the COVID-19 public health emergency ends.

These tests check to see if you have COVID-19. In some circumstances, a home health nurse, laboratory technician, or an appropriately-trained medical assistant may collect your specimen in your home for this test.

Find a partial list of pharmacies participating in the Medicare COVID-19 Over-the-Counter (OTC) tests initiative. Go to the pharmacy website or call the relevant pharmacy for details on participating locations and how to order.

APHIS placed orders for the test kits using Farm Bill funds and sole-source authority. The purchases were made from the manufacturer of the only APHIS Center for Veterinary Biologics-licensed PCR kits for these two diseases.

APHIS is also announcing the availability of a sources-sought notice that will be posted for 90 days to gather additional information from interested diagnostics manufacturers and developers on their ability to supply test kits or devices for three major FADs: FMD, ASF and classical swine fever (CSF).

This is not a solicitation. Information gathered through the sources-sought notice will be analyzed to determine the potential to include additional test kits/devices and their components in the NAVVCB. APHIS anticipates the need for diagnostic products from more than one source and possibly of more than one type to ensure an adequate supply of these products for a sudden surge of diagnostic samples that could result from an FAD outbreak in the United States.

APHIS is taking this action to better understand options for sourcing these test kits/devices and components for these important FADs. APHIS must have diagnostic testing capacity to sustain the disease surveillance and monitoring of animals during a high-consequence FAD outbreak. Without an adequate supply of test kits, disease control and eradication would be challenging; domestic commerce in live animals and their commodities would be severely disrupted; and recovery of international trade would be extraordinarily difficult.

The sources-sought notice is available through Interested vendors should visit the Contracting Opportunities page and search for the Notice ID: 1088535. Interested parties should respond by May 8, 2023. The 2018 Farm Bill established and provided funding for the NAVVCB. It allows USDA to stockpile animal vaccine and countermeasures including diagnostic assays to use in the event of an FMD outbreak or other high-impact FADs, such as ASF and CSF. More information about the NAVVCB and other animal health programs established by the 2018 Farm Bill is available at -disease-information/farm-bill/farmbill12101.

RT-PCR test. Also called a molecular test, this COVID-19 test detects genetic material of the virus using a lab technique called reverse transcription polymerase chain reaction (RT-PCR). A health care professional collects a fluid sample by inserting a long nasal swab (nasopharyngeal swab) into your nostril and taking fluid from the back of your nose. A sample may be collected by using a shorter nasal swab (mid-turbinate swab) or a very short swab (anterior nares swab). In some cases, health care professional inserts a long swab into the back of your throat (oropharyngeal swab). Or you may spit into a tube to produce a saliva sample.

Antigen test. This COVID-19 test detects certain proteins in the virus. Using a long nasal swab to get a fluid sample, some antigen tests can produce results in minutes. Others may be sent to a lab for analysis.

A RT-PCR test called the Flu SC2 Multiplex Assay can detect any of three viruses at the same time: the COVID-19 virus, influenza A and influenza B (flu). Only a single sample is needed to check for all three viruses. This could be helpful during the flu season. But a negative result does not rule out the possibility of any of these infections. So the testing process may include more steps, depending on symptoms, possible exposures and your provider's clinical judgment. 041b061a72
