Weight Loss Blood Test
At-home Test Kit
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.

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.
