What we test
Ten metabolic markers across four systems, measured from a needle-free blood test at home: your baseline first, then a retest every six months.
Cardiovascular risk [2]
Around half
Around half of UK adults have cholesterol above national guidelines, and high cholesterol does not usually cause symptoms: you can only find out from a blood test. [1] [2]
Total cholesterol
The overall amount of cholesterol in your blood: the headline number for heart health.
LDL cholesterol
The carrier cholesterol that can build up in artery walls. Lower is generally better.
HDL cholesterol
The clean-up cholesterol that helps move excess cholesterol away. Higher is generally better.
Triglycerides
The fats your body stores and burns for energy. High levels are linked to a higher risk of heart and circulatory disease.
Liver function [6]
ALT
Alanine aminotransferase: an enzyme that leaks into the blood when liver cells are under strain.
AST
Aspartate aminotransferase: a second liver enzyme, read alongside ALT for a fuller picture.
GGT
Gamma-glutamyl transferase: an enzyme that rises with liver stress, including from alcohol.
Diabetes risk [4]
Almost1.3 million
An estimated6.9 million
Almost 1.3 million people in the UK could be living with type 2 diabetes without a diagnosis, and an estimated 6.9 million are at increased risk based on their blood sugar levels. [3]
Fasting glucose
Your blood sugar level after a period without food.
HbA1c
Your average blood sugar over roughly the past three months.
Thyroid function [5]
TSH
Thyroid-stimulating hormone: the signalling hormone that tells your thyroid how hard to work.
Know your numbers. Change them. See the difference.
