What Happens During a Full Body MOT?
A complete guide to full body health screening in London — what to expect, what's tested, and how to understand your results.
Most of us wouldn't dream of skipping our car's annual MOT — yet when it comes to our own bodies, regular check-ups often fall to the bottom of the priority list. A full body MOT is a comprehensive health screening designed to assess key biomarkers and body functions through detailed blood testing and clinical measurements. Even if you feel perfectly well, screening can still benefit healthy individuals.
What Is a Full Body MOT?
A full body MOT — sometimes called a full body health check or comprehensive wellness screening — is a structured health assessment that typically involves a combination of blood tests, physical measurements, and lifestyle evaluation. The aim is to screen for a broad range of health indicators in one appointment.
Practical Insight: Think of a full body MOT as a baseline snapshot. It doesn't replace medical advice, but it gives you and your healthcare provider valuable data to work with.
What Does a Full Body MOT Typically Include?
Blood Test Biomarkers
| Category | What It Assesses | Why It Matters |
|---|---|---|
| Full Blood Count (FBC) | Red cells, white cells, platelets, haemoglobin | May indicate anaemia, infection markers, or immune function |
| Liver Function (LFTs) | ALT, AST, ALP, bilirubin, albumin | Can suggest how well the liver is processing toxins |
| Kidney Function | Creatinine, urea, eGFR | Helps assess kidney filtering efficiency |
| Lipid Profile | Total cholesterol, HDL, LDL, triglycerides | Important for cardiovascular risk awareness |
| Thyroid Function | TSH, Free T3, Free T4 | May highlight underactive or overactive thyroid patterns |
| Diabetes Markers | HbA1c, fasting glucose | Can indicate blood sugar regulation over time |
| Iron Studies | Ferritin, serum iron, TIBC | Sometimes highlights iron deficiency or overload |
| Vitamin & Mineral Levels | Vitamin D, Vitamin B12, folate | May reveal common nutritional deficiencies |
| Inflammatory Markers | CRP, ESR | Can suggest underlying inflammatory processes |
Physical Measurements
- Blood pressure — a key cardiovascular indicator
- Body Mass Index (BMI) — calculated from height and weight
- Waist-to-hip ratio — sometimes used alongside BMI
- Pulse and heart rate — resting cardiovascular baseline

How Often Should You Have a Full Body MOT?
- Annually — for individuals over 40 or those with risk factors
- Every 1–2 years — for adults aged 30–40 with no known concerns
- As needed — if you experience unexplained symptoms
Practical Insight: Tracking results over time is often more valuable than any single test. Trends in biomarker data can sometimes highlight gradual changes before they become symptomatic. For detailed age-based recommendations, see our guide on how often to get a health check-up in the UK.
