Weight Loss Blood Test

At-home Test Kit

Finger prick weight loss blood test

The Weight Loss Blood Test (£90) measures 21 key biological markers associated with weight management and long-term wellbeing.

The at-home finger-prick test is quick and convenient. You’ll send the sample directly to the lab in the pre-paid envelope.

Once analysed by our state-of-the-art, UKAS accredited medical laboratory, your results are emailed to you.

If you’d like expert guidance, you can add an optional 30-minute telephone consultation with Dr Nisa (£50) to discuss your results and explore appropriate next steps.

No fasting required — we recommend to be well-hydrated beforehand.

UK Only. Open to all, whether or not you are a White Giraffe patient.

    • HbA1c – Reflects average blood glucose levels over the past 2–3 months; commonly used to support assessment of longer-term glucose control.

    • Total Cholesterol – Overall cholesterol level; a broad marker associated with cardiovascular risk.

    • Triglycerides – A blood fat influenced by diet, alcohol intake, and insulin sensitivity.

    • HDL Cholesterol – Often referred to as “good” cholesterol; involved in transporting cholesterol away from arteries.

    • LDL Cholesterol – Often referred to as “bad” cholesterol; higher levels are associated with arterial plaque formation.

    • Non-HDL Cholesterol – Represents total plaque-forming cholesterol; a useful overall heart-risk marker.

    • HDL % of Total – Shows the balance of protective cholesterol relative to total cholesterol.

    • TSH (Thyroid Stimulating Hormone) – The primary regulatory signal from the brain to the thyroid; commonly used to screen thyroid function.

    • Free T3 (FT3) – The more biologically active thyroid hormone, involved in energy regulation.

    • Free T4 (FT4) – The main hormone produced by the thyroid, converted to T3 in the body.

    • ALT (Alanine Transaminase) – An enzyme linked to liver cell stress.

    • AST (Aspartate Transaminase) – An enzyme found in liver and muscle tissue, interpreted alongside ALT.

    • ALP (Alkaline Phosphatase) – Associated with bile ducts and bone metabolism.

    • GGT (Gamma GT) – Often used alongside ALP to assess liver and bile duct health.

    • Bilirubin – Reflects liver processing and bile flow.

    • Total Protein – Combined measurement of albumin and globulins.

    • Albumin – A key liver-produced protein involved in fluid balance.

    • Globulin – A group of proteins including immune-related proteins.

    • Urea – A waste product influenced by hydration and protein intake.

    • Creatinine – A muscle metabolism by-product used to assess kidney filtration.

    • eGFR – A calculated estimate of kidney filtering efficiency.
