COVID-19 Saliva PCR Test

Find out if you currently have COVID-19 with our
Saliva RT-PCR test

This highly accurate, easy-to-use test can determine whether or not you are currently carrying the SARS-CoV-2 virus, which causes COVID-19.

The test requires a simple saliva sample and is processed using an advanced RNA extraction and RT-PCR process.

We don’t recommend using this service for fit-to-fly as typically your sample arrives at the laboratory next day, but can take longer using the COVID-19 Royal Mail service. This test cannot be used for Test to Release.

How it works

Advantages include:


“Excellent service overall”

"Easy to collect the sample, easy to post it, results two days later. And excellent customer service!! Thank you, you're doing an amazing job!"

– Julia

“Fast, smooth and fairly priced.”

“I could not have had a smoother experience. Ordered a test on a Friday morning. It was dispatched an hour later and arrived on Saturday morning. Took the test on Wed and got my results 48 hours later."

Frequently Asked Questions

PCR is a widely used laboratory method that stands for Polymerase Chain Reaction. This test will selectively extract, amplify and identify the viral RNA sequence that corresponds to the virus.

This type of test is particularly sensitive and is the current reference method for detecting SARS-CoV-2 infections as the process finds the specific genetic code relating to the virus and amplifies it by copying it each cycle, where the number of copies double each cycle. The PCR protocol in use utilises 40 cycles in the process, so even a very low viral load in the sample can be detected.

The virus that is amplified in this way is not dangerous as it is inactivated during the preparation process so that only the genetic code is amplified, not the complete virus with its shell structure intact.

A recent study conducted at the Yale-New Haven Hospital and published in the New England Journal of Medicine showed that COVID-19 saliva samples often contained more copies of SARS-CoV-2 than did swab samples, and a higher percentage of saliva samples were positive up to 10 days after the initial diagnosis.

In addition, a study conducted in French Guyane has shown SARS-CoV-2 remains stable within saliva for long periods of time, even at room temperature—a characteristic that comes in handy in sampling situations when temperature regulation may come at a premium, or not at all.

This test will tell you whether or not you are currently carrying SARS-CoV-2, the virus that causes COVID-19, regardless of whether you are displaying symptoms. This test is sensitive enough to detect both symptomatic and asymptomatic individuals. If found positive, you should immediately follow the current best practise guidance provided by the NHS, which we will provided to you with your results.

Those testing positive must self-isolate for 10 days from onset of symptoms, or for asymptomatic individuals from 10 days of the date of your test.

Orders placed on the website before 4PM Monday to Friday are shipped next day using Royal Mail 1st Class Small Parcel. Typically this service delivers the next day or day after, but may be delayed at peak times. Results are returned within 24-48 hours of your sample being received in our laboratory.

This test is highly accurate at detecting both symptomatic and asymptomatic individuals, using saliva as the specimen type. The accuracy of the test is made up of the sensitivity and specificity of the PCR process, combined with the viral load collected in the saliva sample tube and extracted by the RNA extraction step.

A key benefit of this test for “self-test” patients, where the sample is not collected by a healthcare professional, is that saliva provides a more consistent and representative viral load as the sample is less subject to how well swabbing is performed.

The viral load of SARS-CoV-2 in saliva has been studied across 355 samples from staff and patients at Yale-New Haven by the Yale IMPACT research team and Yale University School of Medicine. The team classified saliva samples into low (saliva viral load=3.212-4.4031 Log10 [Log](GE/ml)), medium (saliva viral load=4.4031-6.1106 Log (GE/ml)), and high (saliva viral load=6.1106-10.320 Log (GE/ml)) brackets.

The Nonacus PCR technology was validated and found to have a limit of detection of 2.39 Log10 or 250 copies/mL which is capable of detecting viral load categorised as low in the Yale research with considerable margin.

The Nonacus manufactured reagents are CE-IVD marked for both saliva and swab sample types, and were found to have sensitivity of 98.4% (95% CI 95.34 – 99.45) and specificity of 98.9% (95% CI 97.70 – 99.65) in validation work Department of Health and Social Care in validation work carried out in December 2020.

This test uses the UK manufactured Nonacus reagents which show this test to be accurate with a RT-PCR limit of detection of 250 viral copies per mL for the N gene target.

The test targets genes in the nucleocapsid gene of SARS-CoV-2, and includes a human control to ensure that the RNA extraction process worked correctly.

We will provide you with guidance based on “what your test result means” on the NHS website. In addition, we have a duty to report any positive results to the Test & Trace program. Please see our FAQ “What happens to my personal data including my saliva sample” on the data that will be shared in this instance.

This service is not designed to be used for “Fit to Fly” or “Test to Release.” Fit to fly and Test to Release is not a medical care service, and therefore is a more expensive service to offer.

In addition, we do not recommend using services that use Royal Mail COVID-19 Tracked Returns service as the logistics solution for returning samples to the laboratory, as the service is not guaranteed to deliver a result in the timescale required for your flight.

We find 88% of samples arrive at the laboratory within 48 hours using Royal Mail COVID-19 Tracked Returns 24 in normal circumstances, whereas around 12% take 3-7 days to arrive. The Royal Mail service is affected by peak season demand (such as Christmas) as well as staff shortages in the case of Covid-19 outbreaks at sorting facilities.

This means that the test has been validated by the manufacturer and is in line with the health and safety standards of the European Economic Area

After you have activated your sample and filled in your sample label, all you need to do is fill the sample tube with a small amount of saliva. Then, close the funnel cap until you hear a click in order to release the mixing agent with the rest of your sample. Make sure not to eat or drink anything for 30min before taking the sample.

You have two months from purchase to use your kit, after which time the kit is invalid.  

We issue a doctors report alongside your result. The report will show your name, the laboratory’s name including UKAS number, doctors signature and GMC number, date the sample was taken, date the sample was processed and your result. This testing is overseen by the clinical advisory team at Testing For All.

This report is not intended to be a fit to fly or test to release certificate, but is a doctor’s report confirming the result of your test as part of the medical care that Testing For All offers.

This COVID-19 Saliva PCR Test is provided for the purposes of medical care, which means the service is for the protection, maintenance and restoration of the mental health of the person concerned.  This includes the diagnosis of illnesses, the provision of analyses of scans or samples and helping a health professional, hospital or similar institution to make a diagnosis.

We do not recommend this as it is not a validated approach, and it will lower the sensitivity of the test.

No, this test checks for current infections only though will typically return a positive result for up to 25 days post infection. In order to find out whether you have been exposed to COVID-19 in the longer past and have developed antibodies, you can take our home antibody test.

Privacy is everything to Testing For All. To understand our stance please refer to our privacy notice.

Your sample is anonymous to our lab partners, however positive tests will be reported by Testing For All to Public Health England in accordance with UK regulations.
We will never sell your data including your saliva
We will delete your data at the end of the pandemic subject to regulatory data retention requirements

If you are offered this test by your employer, then your result will be shared in accordance with the Employee Privacy Notice.
