Benefits of Taking Our At-Home Coronavirus Saliva Test?

  • null

    More comfortable

    Avoid the discomfort of an invasive nasal (nasopharyngeal) swab, which must be inserted deep into the nose and/or throat.

  • null

    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 the lab. Unlike deep nasal swabs, there is no need for a trained medical professional to be on hand.

  • null

    Accurate results

    Viral PCR tests have a high sensitivity and specificity. This means that if you test positive, we can be extremely confident that you do have COVID-19. Recent studies suggest that saliva testing is more sensitive for SARS-CoV-2 detection compared to nasopharyngeal swabs.1

  • null

    Quick results

    Once the lab receives and processes your saliva sample, we’ll get your results to you within 36 hours via SMS text message.

  • null

    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.

Why you might need to take a Coronavirus Saliva Test?

  • Taking this coronavirus home test will ensure you take proper precautions for self isolation and hygiene to prevent the virus from spreading.
  • This reliable coronavirus test gives you clarity on whether or not you need to self isolate, if you have any of coronavirus-related symptoms. See the government guidelines for further details.
  • The Coronavirus Saliva Test Kit can be appropriately used for many situations: someone you’ve been in contact with has coronavirus, before you travel, going back to work, or ensuring its safe to see family and friends.
  • If you are showing any symptoms. The main symptoms of coronavirus (COVID-19) to look out for are: a high temperature, a continuous cough, a loss of smell or taste.

The Coronavirus Saliva Testing Kit is one of the world’s first saliva tests for the identification of the SARS-CoV-2 virus that causes COVID-19.

This test uses the RT-PCR method and protocol defined by the US Centre for Disease Control (CDC)1 and has been extensively validated by a UK-based laboratory for the detection of coronavirus.

The NHS are currently investing in coronavirus saliva tests that are more accurate than the current nasal (nasopharyngeal) swabs. With Hydro-X you are guaranteed a fast delivery for a coronavirus home test, with quick results so you can act promptly and accordingly.

The 3 main requirements we expect these tests to fulfil are:

  • Individual use – those who are concerned they might have contracted COVID-19 and wish to carry out a Coronavirus Test on themselves, but perhaps are not currently showing symptoms, therefore can’t take a test via the Government programme
  • Business batch-testing – organisations who wish to carry out periodic sampling of their workforce to proactively respond to coronavirus case incidences
  • Regularised testing of key personnel / frequent flyers – weekly testing using our Coronavirus Saliva Test Kit provides a method that guarantees both personal and group safety

How long does it take to get Coronavirus Test Results?

Once the saliva sample is collected in the tube and then sent back to the lab for testing, you will receive a text (SMS) message in less than 36 hours with your coronavirus test results.

The Coronavirus Saliva Test Kit has a shelf life of 2 years, so feel free to buy and use later. Preparation is the at most importance in these times.

What’s included in the Coronavirus Saliva Test Kit?

  • Spital-capturing test tube
  • Neutralising liquid to make safe the sample for transport (included in the test tube)

Frequently Asked Questions


No... Hydro-X's expertise, for more than 35 years, has been in supporting our customers to reduce risk in the workplace. We do this in many ways: from specialist compliance service provisions, to accredited training, to PPE and consumables supply. In light of current business risks, along with requests from our customers, we have worked hard over recent months to partner with several, specialist epigenetic testing providers. Now we can extend this new facility of Coronavirus Saliva Testing to our customers, without impacting any supply to the UK Government and NHS. As such, the look of the box that the test arrives in may change over time as we balance capacity between each provider to ensure continuity of supply.
This test can be taken at any time of day, although 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. 1. Tajima, Y., Suda, Y., & Yano, K. A case report of SARS-CoV-2 confirmed in saliva specimens up to 37 days after onset: Proposal of saliva specimens for COVID-19 diagnosis and virus monitoring. Journal of Infection and Chemotherapy (2020)
There isn't one. Cost of materials has come down significantly in recent months and we are happy to pass on those cost savings to our customers. The Hydro-X Group has never and will never take commercial advantage in matters relating to health, safety, and compliance.
With our CE marked Coronavirus saliva test, the collection of the sample can be done anywhere - at home, work or in the clinic. Other tests (such as nasopharyngeal swabs) normally require a trained medical professional to administer correctly and are typically much more invasive and painful.
We have worked hard with our supply partners to ensure that any commercial availability to organisations that wish to proactively test their staff for coronavirus, or make tests available to their staff have the facility to do so without any impact whatsoever on Government and NHS supply. The UK Government's own supply chain sits outside of this one, though should a time come when our supply of tests is called upon in the national interest we reserve the right to divert supply accordingly. In the meantime we are taking all possible measures to ensure supply to our customers for the near future.
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 continuous cough, high temperature, and/or loss of taste of smell), you should self-isolate and stay at home for at least 7 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.
This test detects whether or not you are currently carrying the SARS-CoV-2 virus that causes COVID-19 (at time of testing). You may have heard this test also referred to as an antigen test or 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 their saliva and therefore test positive. There are three possible outcomes from the test:
  • Positive - testing positive for the virus means that the sample provided contains SARS-CoV-2 RNA. This result could be returned even in the absence of symptoms.
  • Negative - this result means that the sample provided does not contain detectable levels of SARS-CoV-2 RNA. However, you could have been previously infected by the virus and you could still be infected at a future date.
  • Inconclusive - this result means that the test results did not meet the requirements to be reported as a positive detection of SARS-CoV-2 RNA in the sample, and should be treated clinically as Not Detected. However, this also means that there was partial detection of a signal from SARS-CoV-2 that warrants notification under duty of care for further investigation. Re-testing in these cases is recommended.
  • Failed - this result means it was not possible to accurately process your test in the laboratory. This is normally due to an incorrect saliva sample being provided (i.e. not providing enough spit, not mixing with the stabilizing fluid or eating/drinking before the test). We recommended taking another test as soon as possible.
* Important note: a negative test result does not preclude current or later infection and the development of COVID-19 symptoms should not be ignored.
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. Our COVID-19 saliva test is an antigen (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. * Please be aware of at-home antibody tests currently being sold online. It is against Government advice to use these as it is very unclear how effective these tests are at identifying the presence of antibodies from blood from the fingertip.
The test has a high sensitivity and specificity. This means that the likelihood of receiving a false negative or false positive test result is very low. The test is validated as having 100% sensitivity at viral loads of 750 copies/mL or greater in in vitro limit of detection (LOD) testing. In other words, a positive result was correctly called 100% of the time when 750 copies of synthetic viral RNA per mL were spiked into a saliva sample (using ISO approved RNA control spike-in material) To put this figure in context, typical transmissible viral loads (that cause infection) are usually several fold higher, with viral loads between 10,000 and 100,000,000 copies/mL commonly seen in saliva samples of patients who test positive for SARS-CoV-2.2-4 This means there is a very low likelihood of actually carrying the COVID-19 coronavirus but falsely receiving a negative test result. When tested against samples containing other similar human viruses or those confirmed not to contain SARS-CoV-2, positive results were not seen, showing the specificity of RT-PCR coronavirus tests to be very high.5-7 This means there is an extremely low likelihood of receiving a positive test result despite not carrying coronavirus. (Note that negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations, patient history, and epidemiological information such as history of exposure to the virus - US FDA advice). 8
