Our test is highly sensitive and uses a technique called RT-PCR, which works by detecting the viral RNA. This test will determine if someone is positive for Coronavirus. It can detect the presence of the virus even before symptoms begin to show. Some people never get symptoms. They may still be infectious to a vulnerable friend or family member.

No, this is not the case. The common cold and flu can give similar symptoms to coronavirus infection. However, the RT-PCR test is extremely specific. The test detects the genetic material (the RNA) of the SARS-CoV-2 virus exclusively. The test is not affected by any other virus in the sample.

For your convenience, we’ll send the saliva collection kit directly to your home or location of choice. We provide the saliva collection instructions in the kit, and once you’ve collected the sample, simply return it in the prepaid envelope to the lab for analysis. You can expect to be notified of the results in 2-3 days.

We treat coronavirus testing as priority, so results are issued 2-3 days after the laboratory receives the sample.

FGIH will send you an email when the results are ready. Be sure to provide the most relevant email address for you to receive your results.

Yes, the RT-PCR tests used to detect coronavirus are fully validated in the laboratory. FGIH scientists
run the tests and the results are analysed, verified and resulted by our clinical virologists.

This RT-PCR test will tell you if you are currently infected with coronavirus. It will not tell if you have been infected in the past or whether you are currently immune. This is because the virus is eliminated from the body once you recover, so these tests cannot detect if you’ve previously been infected.

The RT-PCR technique is extremely sensitive, however, it is not possible to guarantee that any test kit is 100% accurate. While unlikely, there is a possibility that the test produces a false positive or negative even when used correctly.

There are THREE possible testing outcomes.

Positive – A positive result indicates that you are presumptively infected with the coronavirus, based
on the RT-PCR test detecting RNA from SARS-CoV-2 in your saliva sample. Please consider yourself to
be contagious. You must self-quarantine and follow current local recommended guidelines. Only
contact your Dr if you are unable to manage your symptoms, should they develop.

Negative – A negative test result indicates that SARS-CoV-2 RNA was not detected by the RT-PCR test
in the specimen above the threshold of detection. Note that a negative result does not rule out
current or future infection by coronavirus. It is imperative to consider any recent exposure,
symptoms or additional diagnostic test results (e.g., for other respiratory illnesses). Furthermore, a
negative coronavirus test should not be used as the sole basis for treatment management decisions
and the full clinical history should be considered.

Invalid – If you receive an invalid result, it means the test results did not meet the diagnostic
requirements to be reported as positive or negative for coronavirus. A repeat test is recommended.

Please ensure all sampling instructions are followed carefully as eating or drinking just before taking
the test may have affected the sample. Incorrect sampling is the most common cause of an invalid

  • If you have symptoms, or have tested positive, do your best to stay as far away from other members of your household as possible. Be extremely cautious around the elderly or anyone who is clinically vulnerable with whom you share a household.

  • Remember to wash your hands regularly for 20 seconds using soap and water, or use hand sanitiser, and always cover any coughs and sneezes.

  • If you had contact with people outside your household within 48 hours of you developing symptoms, consider alerting them to let them know you are experiencing symptoms of COVID-19.

  • Note that should you test positive for COVID-19, you must log into the NHS Test and Trace service
    website and provide information about recent close contacts.


  • If you feel you cannot cope with your symptoms at home, or your condition gets worse, then use the
    NHS 111 online COVID-19 service. If you do not have internet access, call NHS 111. For a medical
    emergency dial 999.
