Science for a healthier life

At SELFCHECK®, the quality and reliability of our health screening tests is prioritised above everything else. All our products are assembled at our UK medical device facility, which is ISO13485:2016 certified for research and development, as well as medical diagnostics assembly.

The science behind SELFCHECK®

Professional customer care when you need it

With 20 years experience developing new medical diagnostics for use in the hospital laboratory as well as for self-testing, we have the expertise to provide prompt, professional customer care, if you need help to understand how your test works, or what your test result means.

An innovative lancet

The Unistik® 3 Extra safety lancets (finger-prickers) supplied with our blood tests are manufactured by Oxford based Owen Mumford Ltd, who supply the same lancets to the NHS. These lancets have been selected by us because of their ease-of-use, track record of 100% activation every time (1), and feature Comfort Zone Technology™, which is specifically designed to reduce discomfort associated with capillary blood sampling. This technology means that when the lancet is pressed against the finger tip, a series of raised dots stimulates the nerve endings, sending a powerful message of comfort to the brain which masks the weaker pain stimulus from the finger-prick. The Unistik® 3 Extra lancet is designed to produce over three times the amount of blood required for a SELFCHECK® test*, so providing you follow the instructions, you should not have any problems getting enough blood - and we include a second lancet just in case.

Safe and simple blood collection

Self-test blood tests need a thin tube called a pipette to collect the blood drops from your finger tip, and to transfer them to the test device. SELFCHECK® blood tests use only soft, flexible plastic safety pipettes, and do not contain any thin glass tubes to collect the blood sample. The pipette is designed to automatically collect the correct amount of blood, and is manufactured by an ISO 13485: 2016 certified company, compliant with IVDR (EU) 2017/746, and registered with the UK MHRA.

Reliable devices

Most of our SELFCHECK® test devices are exclusively made for us by VEDALAB in France. The same devices have been used in Europe by hospitals and laboratories for over ten years. VEDALAB are at the forefront of self-test innovation in Europe and continue development of new tests for use in the hospital laboratory and at home. As you would expect, all our medical tests are CE certified specifically for self-testing according to current UK and EU law and registered with MHRA.

Clear instructions

All self-testing kits sold in the UK must contain a paper instruction leaflet supplied with each test. We have carefully written the instructions in plain English, although we do have to include some technical terms to comply with medical device regulations.

Developing diagnostics in the UK since 2005

The SELFCHECK® health screening range is assembled at the same UK facility that develops and manufactures our hospital and research diagnostics. Our research laboratory and production facility is ISO 13485:2016 certified for design, development, assembly and distribution of medical diagnostics, which is independently audited by UKAS certified auditors - the gold standard quality assurance system for medical device companies.

In 2025, we launched a simple 10 minute test for researchers and doctors to help with the diagnosis of sepsis. The imiwn sTLR2 RAPID test was developed at our R&D lab in North Wales, and shows potential for providing additional insights into inflammation and sepsis compared with traditional biomarkers such as CRP. For further information see imiwn.com

Our scientists are currently collaborating with an NHS initiated project to develop further innovations in self-testing to monitor chronic diseases at home.
