Advantages of our saliva test

  • Do it yourself

    Saliva samples can easily be collected at home or in the workplace. Simply provide a small sample of your saliva in a collection tube and send it back to our lab. Unlike deep nasal swabs, there is no need for a trained medical professional to be on hand.

  • Accurate results

    Viral PCR tests have a higher sensitivity and specificity than other types of COVID test such as LAMP or lateral flow testing. This means that if you test positive, we can be extremely confident that you do have COVID-19. Recent studies also suggest that saliva testing is more sensitive for SARS-CoV-2 detection compared to nasopharyngeal swabs.1

  • Quick results

    Once we receive and process your saliva sample, we’ll get your results to you within within 36 hours via SMS text message and email.

  • Minimise risk

    Identify and isolate asymptomatic individuals (those who carry the virus but have no symptoms) quickly and effectively, reducing the risk of workplace outbreaks.

Receive your results

Order as many testing kits as required for your workplace, business, or personal use. Orders received before 2pm (or 10:00am Saturdays) will be dispatched same day by Royal Mail guaranteed next day delivery service.*

(*Note: If you are purchasing for day 2 & 8 testing or Test to Release purposes, your kit/s will be dispatched on the relevant day of your quarantine period e.g. days 2, 8 and 5 respectively. For Test to Release purposes, if the 5th day of your quarantine period is a Sunday, you will receive your test kit the following Monday).

Once you’ve received your kit(s), you can distribute them to your colleagues, clients, or family members as required. Each user can then individually register their saliva testing kit and contact details online. This allows us to track a saliva sample anonymously through the testing process and send each user their results privately via SMS text message and email.

Simply provide a small sample of saliva in the collection tube. Once collected, send it back to us at no additional cost using our prepaid Royal Mail Tracked 24 service, or via a Next Day Delivery service for a guaranteed delivery time.

Your saliva sample will undergo RT-PCR testing for viral RNA at our UK-based laboratory. This will detect whether you are infected with the SARS-CoV-2 virus.

Get your results within 36 hours of your sample being received at the laboratory. You will receive one of four possible results:

  • Positive – you most likely* have an active COVID-19 infection (SARS-CoV-2 was present in your saliva at the time of testing).
  • Negative– you most likely* do not have an active COVID-19 infection (SARS-CoV-2 was not present in your saliva at the time of testing).
  • Inconclusive– you may or may not have coronavirus. The laboratory results may have only partially detected SARS-CoV-2 RNA in your saliva. Retesting is recommended – we’ll send you a new saliva test kit free of charge. In the meantime, you are advised to behave as if you have a positive test result and are currently carrying coronavirus – you should therefore self-isolate and stay at home until you receive the results of your retest.
  • Failed- we were unable to successfully process your sample. Retesting is recommended- we’ll send you a new saliva test kit free of charge.

Each user will receive their results via SMS text message or email. If you requested a 'fit-to-fly' certificate at registration, you will be able to download your certificate via our secure online portal. Note that where your test was purchased on your behalf by an employer, we will also share your test results with them. Return of the sample is an acceptance of these terms.

Please refer to our results guidance for more information

*No test is 100% accurate. If your test comes back positive for COVID-19 then we can be very confident that you do have COVID-19. However, people with COVID-19 can be missed by these tests. If you have symptoms of COVID-19, it is safest to self-isolate, even if the test does not show COVID-19.

Frequently Asked Questions

This test detects whether or not you are currently carrying the SARS-CoV-2 virus that causes COVID-19.

You may have heard this test also referred to as a PCR test.

It detects the presence of genetic material, called RNA, that is specific to the SARS-CoV-2 virus. If you are currently infected with this coronavirus, you will shed virus particles (which contain viral RNA) into your saliva and therefore test positive using our assay.

If you test negative, then you are most likely not currently infected with the coronavirus that causes COVID-19 (at the time of testing).*

* Important note: a negative test result does not preclude current or later infection and the development of COVID-19 symptoms should not be ignored.

A positive test result means that you were most likely infected with coronavirus (SARS-CoV-2) when you provided your saliva sample, and can give the virus to others.

According to government guidelines, if you had or currently have symptoms of COVID-19 (e.g. a new onset cough, high temperature, and/or loss of taste of smell), you should self-isolate and stay at home for at least 10 days from when your symptoms started.

If you do not have symptoms, you must immediately self-isolate for 14 days.

For more information, please visit the Public Health England and NHS guidance pages.

It’s important to be aware that in order to detect the virus, the ‘viral load’ in your system must be of a sufficient level to detect a positive result. For example, if you caught the virus on Monday and gave your sample on the following Tuesday morning, the viral load will not have had sufficient time to build up to detectable levels and therefore you would likely get a negative result, despite carrying coronavirus.

According to current government travel quarantine rules, “a test after 5 days of self-isolation provides materially better results, as it allows time for the virus, should it be present, to incubate, helping reduce the risk of a false negative result.” For this reason, we would advise anyone carrying out a test who wanted to optimise the likelihood that a negative test result is accurate at the time the sample was provided, to self-isolate and provide their sample on day 5 of their isolation or later.

Finally, it is important to note that while the sensitivity levels of PCR tests for detecting coronavirus is very high, no test of this kind is 100% accurate and precautions should still be taken. A negative result should not be used to undertake activities contrary to government advice and anyone exhibiting symptoms of COVID-19 should self-isolate, even if a test does not detect coronavirus.

Multiple clinical validation studies have been conducted on the assay used by FitnessGenes, including an analysis of 488 blinded samples tested using the current standard of care assays in two clinical ISO15189/UKAS accredited laboratories.

Diagnostic sensitivity has been established at 98.40%. This means there is a very low likelihood of actually carrying the COVID-19 coronavirus but falsely receiving a negative test result.

Diagnostic specificity has been established at 99.34%. This means there is an extremely low likelihood of receiving a positive test result despite not carrying the COVID-19 coronavirus.

Yes - our sample collection devices require no special storage conditions and can be kept at home at room temperature, so you’ll be fully prepared for your next trip or should you require a quick test result.

This test can be taken at any time of day, although preliminary evidence does suggest that it may be better to provide a saliva sample early in the morning rather than later in the day.1

If you have symptoms of COVID-19 (e.g. a new onset cough, high temperature, and/or loss of taste or smell), it is generally best to take the test within the first 5 days from when your symptoms started. This is because you shed more virus particles into your saliva during this time period, making it easier to detect the presence of SARS-CoV-2 via testing.

Time windows between 48 - 96 hours are normally given by your airline or the country you are flying to, and you must ensure your sample is provided within this window in order for your certificate to be valid.

Unfortunately we are unable to advise on individual cases as travel regulations are continually being updated and are subject to change. We advise that you please check the individual requirements for your carrier and destination carefully before purchase, and before providing your sample, to ensure this service meets the stated requirements and that you provide your sample at the correct time.

You can view or download a copy of your COVID 'Fit to Fly' certificate via our secure online Portal. Your certificate will be available from the moment your result is received.

Your data is securely protected and to access your certificate you will need to login using the last 4 digits from your sample barcode and a secure passcode provided to you upon successful registration of your sample.

Whilst our lab works through the weekend processing samples, our courier Royal Mail unfortunately doesn’t, and no deliveries will be received at the lab on Sundays. Samples that do not arrive by Saturday therefore will not be received and booked in until Monday. If your flight is on a Tuesday or Wednesday, you may need to consider an alternative test provider who collect and deliver over the weekend.

While all our samples are returned via a Tracked 24 service free of charge, we do advise that where results are required in a time sensitive manner such as for fit to fly puposes, customers arrange a next day guaranteed delivery option such as Royal Mail Special Delivery or courier service. In these circumstances we will refund the cost of the prepaid postage.

Yes – you can have no symptoms and still be carrying and spreading coronavirus.

Although estimates vary considerably, studies suggest that anywhere between 5 and 80% of people testing positive for SARS-CoV-2 may be asymptomatic.1

While the relationship between viral load and infectiousness is yet to be fully elucidated, one modelling study, based primarily on epidemiological data, estimated that 44% of transmission could occur before first symptoms of COVID-19 present.2 Therefore, identifying a carrier before the onset of illness could prevent many more infections.

No – this is not an antibody test.

An antibody test assesses whether you have already had COVID-19. It involves taking a blood sample and testing for the presence of antibodies to the SARS-CoV-2 virus. Generally speaking, antibodies may be found 2 weeks after infection. Scientists are still unsure of how long these antibodies remain in the bloodstream and whether/for how long they confer immunity to redeveloping COVID-19.

The FitnessGenes COVID-19 saliva test is an antigen or PCR test. It assesses whether you are currently carrying the SARS-CoV-2 virus. It does NOT assess whether you have had COVID-19 in the past.

No – this test only shows whether a person currently has COVID-19 and is carrying the SARS-CoV-2 virus at the time of testing.

If you receive a negative result, it is impossible to tell whether you previously had COVID-19 and now carry antibodies to the SARS-CoV-2 virus. An antibody test is required to find this information.

A 'failed' result means that we were unable to process your saliva sample at our laboratory.

In this event, we will send you a new saliva test kit free of charge for retesting.

If you receive a 'failed' result and are displaying symptoms of COVID-19 (e.g. a new onset cough, high temperature, and/or loss of taste of smell), then, as per government guidance, you should stay at home and self-isolate for at least 10 days from when symptoms started.

If you receive a 'failed' result and do not have symptoms of COVID-19, then you do not need to self-isolate.

An 'inconclusive' result means that the test may have only partially detected the presence of SARS-CoV-2 in your saliva, but the signal did not meet the criteria to be confirmed as a positive result.

If you receive an ‘inconclusive’ result, we recommend retesting. We will send you a new saliva kit free of charge.

In the meantime, you are advised to behave as if you have a positive test result and are currently carrying coronavirus – you should therefore self-isolate and stay at home for 10-14 days (see below) or until you receive the results of a retest.

According to government guidance, someone with an inconclusive result should self-isolate for 10 days from when symptoms started. If not showing symptoms, you should self-isolate for 14 days from when your original saliva sample was first provided. If you subsequently receive a negative test result, you can stop self-isolating.

In order to provide a sample, a user must be able to spit enough saliva to fill the collection device (approximately a teaspoon or so). For this reason, this test may not be suitable for very young infants, and we advise you check they are able to fulfil this requirement before purchase.
