Home Blood Tests: A Complete Guide to Private Testing in the UK
A complete guide to home blood tests in the UK — how private testing works, what you can check, and how to get laboratory results without a GP referral.
Published 3 September 2026
What Is a Home Blood Test?
A home blood test lets you collect a small finger-prick blood sample at home and post it to a laboratory for analysis — with no GP appointment required. Your results are then sent securely to your email, usually within 24–72 hours of the laboratory receiving your sample.
Home testing has become a popular option for UK adults who want faster, more discreet access to health insights, whether for general wellbeing, energy, hormones or heart health.
How Does Home Blood Testing Work?
The process is designed to be simple and convenient:
- Order your test online — choose a health bundle or individual test.
- Receive your kit — a CE & UKCA marked collection kit is delivered to your door.
- Collect your sample — follow the included instructions to take a finger-prick sample.
- Return it by post — use the prepaid packaging provided.
- Get your results — your laboratory report is emailed to you as a secure, password-protected PDF.
What Can You Test For at Home?
Modern capillary collection supports a wide range of biomarkers, including:
- Cholesterol and lipids — heart health markers such as HDL, LDL and triglycerides
- Blood sugar — HbA1c for longer-term glucose levels
- Liver and kidney function — organ health markers
- Thyroid hormones — TSH, Free T4 and Free T3
- Vitamins and minerals — vitamin D, active B12, ferritin
- Hormones — testosterone, cortisol, female hormone profiles

Yes. Samples are analysed by our partner laboratory, one of the UK's leading diagnostic providers.
