Medical testing facility

We offer both the golden standard PCR-test and the rapid antigen test for detecting SARS-COV-2, the virus that causes COVID-19. The RT-PCR test uses the revolutionary technique in microbiology, the polymerase chain reaction, to amplify the viralgenome and sequence specific probes to detect the target amplified genetic material. The Kits used are CE marked and have been validated by PHE in independent NHS laboratories. 

The rapid Antigen test uses antibodies that target viral antigens on the SARS-COV-2 virus. The targeted binding of the antigen to the antibodies in the test device trigger a detectable colour change signifying the presence of SARS-COV-2 viral proteins.

For the nasal and nasal/throat swabs we use CE marked collection devices. The first step of the laboratory test (RNA extraction) uses a CE marked kit and established method. A PHE/NHS laboratory and privately corroborated PCR detection kit is then used which is also CE marked. The test process is operated to ISO 15189 standard and the UKAS accreditation process is underway.

The test is not operated in the US currently so FDA EUA approval is not required

Depending on the customer’s preferred protocol we use nasal (not nasopharyngeal) or nasal/throat sampling using a CE marked sterile swab (synthetic flock material), used dry (no viral transport medium is employed).

Samples can be self-collected or collected by a trained professional at one of our clinics.

Assay is not intended for customer use; samples are transported to the testing laboratory. Alternatively, you can attend the clinic and a member of our team will conduct the test for you.

The PCR negative and positive results are reported to Public Health England and Public Health Scotland (depending on the location of the testing laboratory), who receive full details of the individuals concerned.

The shelf life of the swab kits is indefinite as they are a synthetic flock material with a plastic stem, sealed in a plastic sleeve and supplied sterile by the manufacturer.

Before the end of your trip: Check whether the country you are returning from is on the government travel corridor list. If your country is not on the list, order a PCR test-to-release kit online. You will receive a swab kit in the post and instructions for collecting the sample. Alternatively, the sample can be collected by a trained professional at one of our clinics. Then just post the swab to the lab and wait for your results.

Day one: Arrive in England from a quarantine country. Go straight to the place you plan to self-isolate. Start self-isolating according to the UK government’s instructions.

Day five: Your swab kit will arrive in the post at your self-isolate address. Complete the kit and return it via a royal mail priority post box the same day.

Day seven to eight: Get your results. If negative, you are to end self-isolation.

Each test costs £99 (standard- 48 hr). Rapid result= (24hr) £135. Currently, our order system is limited to 1 test at a time due to requiring a unique booking reference for the passenger locater form, so if you need more for your family please place separate orders.

Once you have registered online for a test the swab kit will be sent to your selected address. When you have received your test kit take the time to read the instructions leaflet and collect the sample as instructed. Then simple place the swab into the sample bag provided and post the swab kit to the laboratory. You will then be sent the results of the test via a secure emailing system called Egress. Once you have logged in you will be able to access your test result and be provided with your the fit-to-fly, test and test-to-release certificate.

If you have registered through one of our clinics you will be provided with an appointment to have the sample collected by a trained professional. Alternatively, If you have booked a test through our website, the test kit will be sent to the address selected.

Your swab test kit is posted to your self-isolation address via Royal Mail first class delivery on day 4 of isolation, arriving on day 5 depending on your location.

Note: Protein Technologies cannot be held responsible for delays in the post. 

On your arrival back in the UK, your test will be then be dispatched on Day 4, and will arrive with you on Day 5.

We provide both test-to-release and fit-to-fly services and produce certification for both requirements. Please specify when booking a test which certificates are required to ensure the appropriate test certificate is sent out.

Please get in touch with us or reply to your confirmation email with your correct flight details and the team can update it.

No, we are currently only using the Royal Mail service as it is linked to tracking. Completed test kits must be dropped into a priority Royal Mail post box. We are working on a FedEx option and some drop points in various cities and will have various solutions announced shortly.

No, we do not allow drop off at the labs for safety reasons. Completed test kits must be dropped into a priority Royal Mail post box.  We are working on a FedEx option and some drop points in various cities and will have various solutions announced shortly.

We offer both postal swab collection and clinic sample collection services. Please select the best option for you when booking your test online.

Once received back at our lab you can expect the results within 24 hours or 48 hours depending on the service selected. We will send you an email notification once the swab sample has been received by the lab.Please note: we are unable to control any delays with royal mail and the post may take longer than expected, especially over the holiday period.

Rapid Antigen test: This is a lateral flow chromatographic test, much like a pregnancy test, which detects the presence of the SARS-COV-2 virus in patient samples. The test device contains antibodies targeted against viral proteins present on SARS-COV-2. 

RT-PCR test: The golden-standard for detection of the virus is the RT-PCR method. We utilise the taqman PCR detection system where sequence specific primers targeted regions of the SARS-COV-2 genome. Amplification of viral genetic information indicates the presence of a viral RNA template and the SARS-COV-2 virus.

Yes, we provide a number of solutions from regular lab-based testing to developing regular screening programmes.

In the first instance we propose designing and agreeing a clinical governance approach to workplace testing and then we will provide a solution to support this.

Yes, we have a number of remote solutions if you decide you only want to do ad-hoc testing

On 14th December 2020 the SARS-COV-2 VUI 202012/01 was reported by the UK governing bodies to the WHO. Epidemiological analysis of the new variant identified has revealed over 50% of isolates in the SE of England were the new COVID variant. This variant has shown increased binding affinity to the ACE2 receptor and subsequently increased transmissibility. Although the variant has shown increased cellular infectivity there has been no reported effect on infection severity or outcome. 

The variant mutations and deletion 69-70 in the spike protein cause a negative result from S-gene RT-PCR assays, however, our assay technique does not use this region due to its high variability. Therefore, this variant mutation has no impact on our ability to detect the SARS-COV-2 virus.

Please note that we are not able to refund any test that have been cancelled within 48 hours of the test getting to the lab. It is possible, however, to reschedule test if required.

For day 2 and day 2 and 8 tests, if your booking number has been used to gain entry to the UK we will not be able to provide a refund.
