Dr Chun Tang has practised as a GP for more than 25 years. He is Medical Director at Northwest Health and Clinical Director at Pall Mall Medical, and he reads every abnormal result that comes back from a test bought here.
GMC 4576963 — verifiable on the GMC medical register.
Why we started
Dr Chun Tang lost his father to bowel cancer. It was found at stage four. Around the same time, his brother's health was seriously affected by a misdiagnosis at the age of 35. Both experiences pointed at the same thing: the outcome in bowel cancer depends enormously on when it is found, and the systems for finding it early are not always available to the people who need them.
In 2019 he founded Biox Medical with his wife Dr Clara Weisshaar and Prof. Dr. Maria-Paz Weisshaar, a microbiologist and pharmacogeneticist, to bring molecular screening tests to the UK. MeCheck is the consumer side of that company — the same tests supplied to private clinics and pharmacies, available directly to people at home.
What makes this different from most home testing
Most direct-to-consumer testing companies are logistics businesses. They ship a kit, a laboratory produces a number, and the number arrives in your inbox. If that number is abnormal, you are on your own with it, usually at the precise moment you are least equipped to interpret it.
We do it differently in one specific way: abnormal results are read by a named GP, and that GP will speak to you. Not a call centre, not a generic advice line. Dr Tang's GMC number is 4576963, and you can look him up on the medical register before you buy anything.
Clinical reporting is provided through Northwest Health Ltd, a clinic registered with and inspected by the Care Quality Commission. That matters because it means the clinical side of this sits inside a regulated provider rather than alongside one.
How we choose what to sell
We distribute tests made by established manufacturers and analysed in accredited laboratories, and we say plainly which is which. ColoAlert is manufactured by biovis Diagnostik MVZ GmbH, part of the Sonic Healthcare group, and analysed exclusively at their ISO 15189-accredited laboratory in Limburg-Eschhofen, Germany. Our wellness tests are described as wellness tests rather than dressed up as medical diagnostics.
