Free Blood Test Analyser: Understand Your Results

Type in the numbers from your NHS or private blood test and get a plain-English explanation of each marker, with evidence-based training, nutrition and supplement suggestions, and a clear flag when a result needs your GP. Built for busy professionals over 30 who want to use their blood work to lose fat, build muscle and live longer.

Not medical advice. This tool uses published UK reference ranges (NHS, NICE, British Liver Trust, British Thyroid Foundation) and peer-reviewed research. It cannot diagnose anything. Always discuss abnormal results and any new supplement with your GP or pharmacist, especially if you take medication or are pregnant.

1. About you

2. Your results

Fill in only the markers you have. Leave the rest blank. Units are the standard UK lab units shown next to each box. The pre-filled example is a real-style result set so you can see how it works; clear it and add yours.

Blood test questions people ask

What is the best blood test for fat loss and energy?

A sensible starting panel is HbA1c, fasting glucose, a full lipid profile (total, LDL, HDL, triglycerides), liver function (ALT, GGT), thyroid (TSH, free T4), vitamin D, ferritin, B12 and CRP. Men can add a 9am testosterone. Most of these are available free through your GP if there is a clinical reason, or privately for £40-£150 in London.

Why does the tool show "watch" when my GP said the result was normal?

Lab reference ranges describe what is common in the population, not what is ideal. The tool shows the NHS reference range and a tighter "optimal" range drawn from research on long-term health. A "watch" result is not a disease; it is a number worth improving with training and nutrition.

Can supplements fix an abnormal blood test?

Only when the problem is a true deficiency (vitamin D, iron, B12, folate). For cholesterol, HbA1c, liver enzymes and blood pressure, the strongest evidence is for fat loss, resistance training, daily walking, fibre, less alcohol and better sleep. Supplements are listed here only where trials support them, and always with a note to check with your GP.

How often should I retest?

Every 12 weeks is a practical cycle: long enough for HbA1c (reflects about 3 months), liver enzymes, lipids and vitamin D to change, and the same length as one transformation block.
