HX Store’s Coronavirus Test Kit is one of the world’s first fully approved coronavirus saliva tests.

It uses the RT-PCR method and protocol defined by the US Centre for Disease Control (CDC)1. Additionally, UK-based laboratories extensively validated this Covid-19 test kit for the detection of coronavirus.

All tests are performed in our certified UK laboratories at the highest clinical standards. Buy a PCR Test Kit from Hydro-X to guarantee quality, with fast results.

How It Works

Order your coronavirus saliva test kit onlineBuy as many coronavirus test kits as required for business or private use. Orders received before 1pm will be dispatched on the same working day.

Our business hours are Monday to Friday. If you order before 1pm Friday you should receive your kit(s) on Monday. However, ordering after 1pm on Friday means you will receive your kit(s) on Tuesday.

Register coronavirus test barcodeOnce you’ve received your Covid-19 PCR test kit(s), each individual must register their kit barcode on the online portal. Samples that are unregistered cannot be analysed. This allows us to anonymously track a saliva sample throughout the testing process, and then send each user their results privately. Please make a record the barcode and keep it safe.

Send coronavirus saliva sample Simply provide a small sample of saliva in the collection tube. Please wait at least 1 hour after drinking, eating, smoking, vaping, brushing your teeth, or using mouthwash. Once the saliva sample is collected in the tube, use the returns label provided. Post it in any Royal Mail post-box via our FREE Royal Mail Tracked 24hr service.

Send coronavirus saliva test sample to the laboratoryYour saliva sample will undergo coronavirus RT-PCR testing for viral RNA at our UK based laboratory. As a result, this will detect whether you are infected with Covid-19.

Receive your coronavirus saliva test kit resultsGet your results within 8 – 36 hours of your sample being received at the lab. Each individual will receive their results via SMS text message. If you requested a ‘fit-to-fly’ certificate at online registration, you’ll be able to download your certificate via a secure online portal.

Coronavirus Private Test Kit Postage Information

If you buy a Covid-19 Test Kit before 1pm, you will be automatically eligible for next working day delivery.

Our business hours are Monday to Friday. Therefore, if you order before 1pm Friday, you should receive your Covid-19 Test Kit on Monday. However, ordering after 1pm on Friday means you will receive your test kit on Tuesday.

A FREE Royal Mail 24hr returns label is supplied in each kit. However, it is recommended that you do not use this label if you wish to send the sample to our lab faster. Instead, we suggest to upgrade to a next day 10am delivery via Royal Mail priority service. Otherwise, please use any other faster courier service if Royal Mail is unsatisfactory in your area. Please ensure the kit is sent to the address noted on the sample box.

How Long Does It Take to Get the Test Results?

Once the lab receives your saliva sample, expect to receive your results within 18 to 36hrs via SMS (text message). Fortunately, the majority of PCR Test Kit results come back within 20hrs. Upon receiving your text message result, you will also receive a downloadable report as evidence. This report will be accessible via an online portal. This can be used as a fit to fly certificate in some cases. However, we always recommend speaking with your travel destination and airline to check their specific requirements.

*If you are using this Coronavirus Test Kit to gain a fit to fly certificate, we STRONGLY recommended to arrange for a next day 10am delivery via Royal Mail. This is instead of using the included returns label. As a result, this ensures your test results are received in time for your flight.

Why choose our Covid-19 Test Kit?

  • null

    Do it yourself

    Simply provide a small sample of your saliva in the collection tube included in the kit. Saliva samples can be collected easily, at home or business. There is no need for a trained medical professional.

  • null

    Accurate results

    Viral PCR tests, like our coronavirus test kit, have a high sensitivity and specificity. If you receive a positive result, we are extremely confident that you are carrying SARS-CoV-2 (COVID-19). Recent studies suggest that saliva testing is more sensitive, in comparison to deep nasal/throat (nasopharyngeal) swabs.

  • null

    Minimise risk

    Know if you have it and follow the rules for self isolation. Additionally, help identify asymptomatic individuals (those who carry the virus but have no symptoms) quickly and effectively. In return, reducing the risk of outbreaks in homes and businesses.

  • null

    Best value

    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.

  • null

    More comfortable

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

  • null

    Quick results

    Once the lab receives and processes your saliva sample, we’ll get your results returned in less than 36 hours via SMS text message. Along with a downloadable report to evidence your results.

What Do the PCR Test Kit Results Show?

  • Positive – This result accurately shows that the saliva sample contains SARS-CoV-2 RNA. Even if you are not experiencing any Covid-19 symptoms, please take precaution for self isolation and follow the NHS Guidelines.
  • Negative – The saliva sample does not contain any detectable levels of SARS-CoV-2 RNA. Nonetheless, please be aware that you could have been previously infected by Covid-19. Additionally, continue to protect yourself and others as you could still be infected at a future date.
  • Inconclusive – The saliva sample did not meet the requirements to successfully detect SARS-CoV-2 RNA. As a result, this should be treated clinically as Not Detected. However, this also means that there was partial detection of SARS-CoV-2, which means re-testing 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 to buy a Coronavirus PCR Test Kit as soon as possible.

How Accurate Is the Coronavirus Saliva Test?

*The Coronavirus Saliva Test Kit has high sensitivity and accuracy to detecting the Covid-19 virus. Therefore, it is extremely unlikely to receive an inconclusive or failed result.

Our Covid Test Kit is validated as having 100% sensitivity at viral loads of 750 copies/ml (or greater) 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. This was using ISO approved RNA control spike-in material.

Typical transmissible viral loads, which cause infection, are usually several fold higher. This includes viral loads between 10,000 and 100,000,000 copies/ml usually seen in saliva samples of patients who test positive for SARS-CoV-2.2-4 As a result, there is a very low likelihood of falsely receiving a negative test result, while carrying coronavirus.

Why You Might Need to Take a Coronavirus Test?

More people have turned to buy Covid-19 Tests Kits for at home use instead, as you cannot receive a free NHS test unless you have Covid-19 symptoms.

You may need to buy a Coronavirus Private Test Kit for these reasons:

  • Seeing family and friends that have not been vaccinated
  • Someone you’ve been in contact with has tested positive for coronavirus
  • Identifying that you are fit to fly with a Covid-19 test
  • Use as a coronavirus business test kit for organisations who wish to carry out periodic sampling of their workforce to proactively respond to any Covid-19 case incidences within the workplace
  • Provides a method that guarantees both personal and group safety for workplace testing key workers

The main symptoms of Covid-19 to look out for are a high temperature, continuous cough and a loss of smell/taste. See the NHS guidelines for further details.
