SARS-CoV-2 Coronavirus Test
Molecular Test for the Detection of COVID-19
SARS-CoV-2 Test (Covid-19)
What is coronavirus (COVID-19)?
COVID-19 is caused by the SARS-CoV-2 virus which is a new virus in humans causing a contagious respiratory illness. COVID-19 can present with a mild to severe illness, although some people infected with COVID-19 may have no symptoms at all. Older adults and people of any age who have underlying medical conditions have a higher risk of severe illness from COVID-19. Serious outcomes of COVID-19 include hospitalization and death. The SARS-CoV-2 virus can be spread to others not just while one is sick, but even before a person shows signs or symptoms of being sick (e.g., fever, coughing, difficulty breathing, etc.).
What is the DxTerity SARS-CoV-2 (COVID-19) Test
The DxTerity SARS-CoV-2 RT-PCR CE Test is an end point reverse transcription polymerase chain reaction (RT-PCR) test followed by detection with capillary electrophoresis (CE) intended for the qualitative detection of nucleic acid from the SARS-CoV-2 in saliva specimens collected from any individuals determined to be appropriate for COVID-19 testing by their healthcare provider (HCP), including from individuals without symptoms of COVID-19.
Important Facts for Patients
- Patients with confirmed COVID-19 have developed fever and/or symptoms of acute respiratory illness (e.g. ,cough, difficulty breathing)
- Limited information is currently available to characterize the full spectrum of clinical illness associated with COVID-19.
- Based on what is known about the virus that causes COVID-19,signs and symptoms may appear any time from 2 to 14 days after exposure to the virus.
- The median incubation period is approximately 5 days, but may range 2-14 days.
- Patients may be asymptomatic (without symptoms) for up to the full period of infection.
- You should be tested because your healthcare provider believes you may have been exposed to the virus that causes COVID-19 based on your signs and symptoms (e.g., fever, cough, difficulty breathing), and/or because:
- You live in or have recently traveled to a place where transmission of COVID-19 is known to occur, and/or
- You have been in close contact with an individual suspected of or confirmed to have COVID-19.
- You and your healthcare provider believe there is another reason to investigate your COVID-19 infection status.
- If you have a positive test result, it is very likely that you have COVID-19. Therefore, it is also likely that you may be placed in isolation to avoid spreading the virus to others. You should follow CDC guidance to reduce the potential transmission of disease.
- There is a smaller possibility that this test can give a positive result that is wrong (a false positive result) particularly when used in a population without many cases of COVID-19 infection. Your healthcare provider will work with you to determine how best to care for you based on the test results along with medical history, and your symptoms
- A negative test result means that the virus that causes COVID-19 was not found in your sample.
- However, it is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID-19. You might test negative if the sample was collected early during your infection. You could also be exposed to COVID-19 after your sample was collected and then have become infected. In particular, people infected with COVID-19 but who have no symptoms may not shed enough virus to trigger a positive test.
- This means that you could possibly still have COVID-19 even though the test result is negative. If your test is negative, your healthcare provider will consider the test result together with all other aspects of your medical history (such as symptoms, possible exposures, and geographical location of places you have recently traveled) in deciding how to care for you. If you have no symptoms but have been tested because your doctor thought you may have been exposed to COVID-19, you should continue to monitor your health and let your healthcare provider know if you develop any symptoms of COVID-19. If you develop symptoms you may need another test to determine if you have contracted the virus causing COVID-19.
If you develop symptoms or your symptoms get worse you should seek medical care. If you have the following symptoms you should seek immediate medical care at the closest emergency room:
- Trouble breathing
- Persistent pain or pressure in the chest
- New confusion
- Inability to wake up or stay awake
- Bluish lips or face
- Potential risks include:
- Possible discomfort or other complications that can happen during sample collection.
- Possible incorrect test result (see positive result and negative result FAQs above)
Potential benefits include:
- The results, along with other information, can help you and your healthcare provider make informed recommendations about your care.
- The results of this test may help limit the spread of COVID-19 to your family and those you come in contact with.

Frequently Asked Questions (FAQs)
COVID-19 spreads from person-to-person. When an infected person coughs, sneezes, or exhales air, droplets containing the virus go into the air and onto surfaces and objects around them. Other people are exposed to the virus by breathing in these droplets or by touching their eyes, nose, or mouth after touching infected surfaces.
There is currently no treatment for COVID-19. Not all patients with COVID-19 will require medical attention, and most people recover within 2 weeks without any specific treatment. For severe cases, hospitalization may be required. Treatment focuses on managing symptoms.
If you have any symptoms concerning for COVID-19 and any of the following conditions or risk factors, which may put you at increased risk of severe illness from COVID-19, you should consult with your healthcare provider before using this test:
- Chronic kidney disease

COVID-19 is very contagious. The risk of getting COVID-19 depends on many factors, including where you live, recent travel history, and close contact with people who have symptoms. It is important to comply with any local travel restrictions and to protect yourself from exposure if you are in a city or area where the disease is spreading.
There are currently no vaccines for COVID-19. The best way to protect yourself is to avoid situations in which you may be exposed to the virus. Everyday actions can help protect you and prevent the spread of respiratory diseases such as COVID-19.
- Avoid close contact with people who are sick.
- Avoid touching your eyes, nose, and mouth.
- Stay home when you are sick.
- Cover your cough or sneeze with a tissue.
- Clean and disinfect frequently touched objects and surfaces.
- Wash your hands often with soap and water for at least 20 seconds.
- Use an alcohol-based hand sanitizer with at least 60% alcohol if soap and water aren’t available. Always wash hands with soap and water if hands are visibly dirty.
If you test positive for COVID-19 and have mild symptoms, the following steps can help prevent the disease from spreading to others:
● Stay home
﹣ Stay in a specific room and away from other people in your home
﹣ Restrict any activities outside your home, except for getting medical care
﹣ Avoid public areas, including work and school
﹣ Avoid using public transportation, ride-sharing, or taxis
● Cover your nose and mouth
﹣ If you are sick, wear a facemask when you are around other people or pets
﹣ Cover your mouth and nose with a tissue when you cough or sneeze, and throw away used tissues
● Wash hands
﹣ Wash your hands often with soap and water for at least 20 seconds
﹣ Wash your hands especially after blowing your nose, coughing, sneezing, going to the bathroom, or before eating or preparing food
﹣ If soap and water are not available, use an alcohol-based hand sanitizer that contains at least 60% alcohol
﹣ Avoid touching your eyes, nose, mouth, and other people with unwashed hands
● Do not share
﹣ Do not share dishes, cups, eating utensils, towels, or bedding with other people or pets
﹣ After using personal items, they should be washed thoroughly with soap and water
● Clean and disinfect
﹣ Clean high touch surfaces such as counters, tabletops, doorknobs, bathroom fixtures, toilets, phones, keyboards, tablets, and bedside tables
﹣ Clean any surfaces that may come in contact with body fluids, blood, or stool
﹣ Use a household cleaning spray or wipes
﹣ Immediately remove and wash clothes or bedding that have body fluids, blood, or stool on them
No. This test is not yet approved or cleared by the United States FDA. When there are no FDA-approved or cleared tests available, and other criteria are met, FDA can make tests available under an emergency access mechanism called an Emergency Use Authorization (EUA). The EUA for this test is supported by the Secretary of Health and Human Service’s (HHS’s) declaration that circumstances exist to justify the emergency use of in vitro diagnostics for the detection and/or diagnosis of the virus that causes COVID-19. This EUA will remain in effect (meaning this test can be used) for the duration of the COVID-19 declaration justifying emergency of IVDs, unless it is terminated or revoked by FDA (after which the test may no longer be used).
