Saliva sampling is fast, non-invasive, inexpensive and painless. In contrast to nasopharyngeal swabbing, saliva sampling meets these criteria. To make the diagnostic acceptable to the largest number of people, especially asymptomatic individuals, massive testing should be based on a sampling procedure that is inexpensive, easy to set up and well accepted by the population. The French health regulatory authority ( Haute Autorité de Santé) has recently included in its recommendations the use of saliva samples for the detection of SARS-CoV-2 in symptomatic individuals for whom nasopharyngeal sampling is difficult, and for mass testing within schools, universities and among health workers. The American Centres For Disease Control and Prevention and the European Centre for Disease Prevention and Control now recommend viral testing from the respiratory system such as nasal or oral swabs or saliva. The recommended diagnosis of SARS-CoV-2 infection from the World Health Organisation is based on real time RT-qPCR detection of viral RNA in respiratory specimen such as nasopharyngeal swabs (NP), bronchial aspiration (BA), throat swab and sputum. When the virus has disseminated throughout a whole country, massive testing becomes of utmost urgent importance to combat the pandemic. To reduce the circulation of the virus in the population, SARS-CoV-2 carriers need to be identified rapidly and isolated as soon as possible, ideally before the onset of symptoms. Propagation of infections by SARS-CoV-2, the coronavirus causing the COVID-19 pandemic, occurs from asymptomatic as well as symptomatic carriers.

If you do not have symptoms and have not been exposed to the virus that causes COVID-19, continue to take steps to protect yourself and others, including monitoring for symptoms.

If you do not have symptoms, but were exposed to the virus that causes COVID-19, you should continue to take recommended steps after exposure.

Contact a healthcare provider if you have any questions about your test result or if your symptoms worsen.

Take everyday preventive actions to prevent spreading an illness to others.

For many diseases, including flu, early diagnosis and prompt treatment is important for preventing severe illness.

You may have another viral infection or illness that you need to get tested for.

You may have COVID-19, but tested before the virus was detectable.

Self-tests, along with vaccination and prevention actions, can help you protect yourself and others.Ī negative COVID-19 test means the test did not detect the virus, but this doesn’t rule out that you could have an infection.

You may get a PCR test as an alternative to repeat testing.Self-tests are more likely to detect the virus if you have symptoms. Take a third test, 48 hours after the second, if the second test was negative and you don’t have symptoms.

FDA recommends people who get an initial negative result on an antigen test, take at least one more test 48 hours later.Although self-tests are usually faster, they are not as good at detecting the virus as PCR tests, meaning you might get a false negative result.These are different from laboratory-based PCR tests or self-collected samples that are sent to a laboratory these may take days to return your result. They give you results in 10-15 minutes and are usually antigen tests.Self-tests detect current infection and are sometimes also called “home tests,” “at-home tests,” or “over-the-counter (OTC) tests.”.Self-tests for COVID-19 give rapid results and can be taken anywhere.
