Finger-Prick Blood Test
Convenient home testing — what works on a finger-prick sample and what doesn't.
A finger-prick blood test lets you collect a small blood sample at home, then post it to an accredited UK lab. Most common biomarkers — thyroid, vitamins, hormones, cholesterol and HbA1c — can be measured reliably from a finger-prick sample.
What it measures
Thyroid (TSH, FT4, FT3)
Vitamins (D, B12, folate)
Hormones
HbA1c & cholesterol
Why it matters
- Home finger-prick kits remove the need to visit a clinic for many tests.
- Some tests — including most autoimmune panels and full hormone profiles — still require a venous sample.
- Following the collection instructions carefully avoids haemolysis (damaged sample) and a wasted kit.
How testing works
- Order a kit online — it arrives by post within 1–3 working days.
- Warm your hands, prick the side of a finger using the supplied lancet, and fill the small tube.
- Post the sample using the included pre-paid envelope. Results are typically returned in 2–5 working days.

Frequently asked questions
Are finger-prick tests as accurate as venous tests?
For most common biomarkers, yes — UKAS-accredited labs validate finger-prick samples against venous standards. A small number of tests are still preferred from a venous draw.
What if I can't get enough blood?
Most providers will send a replacement kit free of charge if the lab can't process your sample due to insufficient volume or haemolysis.
