After purchasing your blood test online you will receive a full kit delivered to your door which you will have to get a blood test

If you decide to test at home a kit arrives at your door with everything you need: a small lancet, collection tubes, prepaid return packaging, and clear step-by-step instructions. The whole process takes about 5 minutes.

Results in 2 working days. From your post box to your inbox — fast, accurate, and doctor-reviewed every time.

Bio sensitive tests are designed to match the accuracy of traditional clinical blood tests, and in many cases they're even more precise. Every sample you send us is analysed at a UKAS-accredited laboratory (ISO 15189 certified) — the same quality standard required of NHS hospital labs. The analysers, reagents, and clinical methods used are identical to those your GP would rely on, and every batch is calibrated daily against international reference standards.

The science behind capillary blood testing — the small finger-prick sample you collect at home — is well-established. For the hormones, vitamins, and biomarkers we measure, peer-reviewed studies have shown capillary samples produce results that closely match venous blood draws when collected and stored correctly. That's why over a million people in the UK now use at-home tests every year, and why GPs and private clinics increasingly accept these results for clinical decision-making.

To ensure your results are reliable, we use highly sensitive assay methods specifically validated for small-volume samples, ship your kit with stabilising agents that preserve the sample during transit, and reject any sample that doesn't meet our quality threshold — sending you a free replacement kit if needed. Every result is then reviewed by a UK-registered doctor before being released to you, so you receive not just accurate numbers but a meaningful interpretation of what they mean for your health.
