Metabolic Health Blood Test Panel – What It Includes, Why It Matters, and How to Understand the Results

Monitoring metabolic health is one of the most effective ways to understand how your body manages inflammation, blood sugar, cholesterol and long-term disease risk. In the UK, more people are choosing comprehensive blood panels to assess their overall metabolic function and gain valuable insights into lifestyle, nutrition and long-term wellbeing.

This Metabolic Health Panel includes five key markers:

  • CRP (C-Reactive Protein), quantitative

  • HbA1c (Glycated Haemoglobin)

  • Uric Acid

  • Lipid Profile (Total Cholesterol, HDL, non-HDL, LDL, Triglycerides)

  • HOMA-IR (Insulin Resistance Index)

Each test provides critical information about inflammation, heart health, carbohydrate metabolism and overall metabolic balance.
Below is a full explanation of what each marker means and the typical UK reference ranges.
(Ranges may vary slightly across NHS and private laboratories.)

1. CRP (C-Reactive Protein), Quantitative – Marker of Inflammation

Why is this test important?

CRP is a protein produced by the liver in response to inflammation. Even low-grade inflammation can influence energy, metabolic function, weight regulation and overall health. A quantitative CRP test identifies whether inflammation is present and how significant it is.

Typical UK reference range:

  • Normal: < 5 mg/L

  • Mild elevation: 5–10 mg/L

  • High: > 10 mg/L

What may the results suggest?

  • Low CRP: no significant inflammation.

  • Elevated CRP: may reflect infection, inflammation, poor recovery, high stress, or certain lifestyle factors.

CRP is not specific to any condition — it simply shows that the body is experiencing inflammation.

2. HbA1c – Glycated Haemoglobin (Long-Term Blood Sugar Control)

Why is it essential?

HbA1c reflects the average blood glucose level over the past 2–3 months. It is one of the most reliable ways to assess long-term blood sugar management and carbohydrate tolerance.

Typical UK reference ranges:

  • Normal: below 42 mmol/mol (below 6.0%)

  • Pre-diabetes range: 42–47 mmol/mol (6.0–6.4%)

  • Diabetes threshold: ≥ 48 mmol/mol (6.5%)

What may the results indicate?

  • Lower HbA1c: good long-term glucose control.

  • Higher HbA1c: reduced insulin sensitivity or prolonged elevated blood sugar levels.

3. Uric Acid – Metabolic & Inflammatory Marker

Why is it tested?

Uric acid is a waste product formed from the breakdown of purines. Elevated levels can be associated with metabolic imbalance, inflammation and reduced detoxification efficiency.

Typical UK reference ranges:

  • Women: 140–360 µmol/L

  • Men: 200–430 µmol/L

What may the results suggest?

  • High uric acid: may be linked with high-purine diet, metabolic stress, poor kidney clearance or increased inflammation.

  • Low uric acid: uncommon and usually not clinically significant.

4. Lipid Profile – Cholesterol & Cardiovascular Health

A complete lipid panel measures:

  • Total Cholesterol (TC)

  • HDL („good” cholesterol)

  • non-HDL cholesterol

  • LDL („bad” cholesterol)

  • Triglycerides (TG)

Why is this important?

Lipids play a crucial role in energy production, cell structure and hormone creation. However, imbalanced cholesterol or triglycerides can be associated with cardiovascular risk factors.

Typical UK reference ranges:

  • Total Cholesterol: < 5.0 mmol/L

  • LDL Cholesterol: < 3.0 mmol/L

  • HDL Cholesterol: > 1.0 mmol/L (men), > 1.2 mmol/L (women)

  • non-HDL Cholesterol: < 4.0 mmol/L

  • Triglycerides: < 1.7 mmol/L

What may the results mean?

  • High LDL / non-HDL: may be associated with cardiovascular risk factors.

  • High HDL: generally considered protective.

  • High triglycerides: may be linked with excess carbohydrate intake, reduced insulin sensitivity or metabolic imbalance.

5. HOMA-IR – Insulin Resistance Index

Why is this test valuable?

HOMA-IR is a calculated score derived from fasting glucose and fasting insulin. It reflects how effectively the body responds to insulin — a key factor in weight regulation, energy levels and long-term metabolic health.

Typical UK interpretation:

There is no universal NHS reference range, but most UK metabolic specialists use approximate functional thresholds:

  • Optimal: < 1.0

  • Moderate insulin resistance: 1.0–2.0

  • Significant insulin resistance: > 2.0

(Private laboratories may provide their own ranges.)

What may the results suggest?

  • Low HOMA-IR: good insulin sensitivity.

  • High HOMA-IR: reduced insulin response, often linked with fatigue, weight changes, hunger swings or high carbohydrate load.

Why is this Metabolic Health Panel useful?

Together, these tests provide a comprehensive picture of:

  • inflammation levels,

  • long-term glucose control,

  • lipid balance,

  • metabolic efficiency,

  • insulin resistance risk factors.

While these results do not replace a medical diagnosis, they offer a powerful foundation for discussing your health with a specialist and making informed lifestyle decisions.
