Weight Loss Monitoring
£199.00
The check-in. Every 3 to 6 months while you're on GLP-1.
Weight Loss Monitoring is the 53-marker companion panel to Weight Loss Commencement. Run it at 3 or 6 month intervals during your weight loss treatment to see how your body is responding — and to spot anything that needs attention before it becomes an issue.
What this panel tracks
- Full Blood Count — full red, white and platelet picture
- Heart Health — full cholesterol panel and Apolipoprotein B
- Kidney Health — including a urine microalbumin check for early kidney-strain detection
- Liver Health — six markers covering filtration and detoxification
- Pancreatic Health — Lipase and Pancreatic Amylase, important when the digestive system is adapting
- Diabetes Health — HbA1c, glucose, insulin and HOMA-IR
- Thyroid — TSH and Free T4
- Hormonal Health — full sex-hormone profile
- Inflammation — hs-CRP
- Vitamins & Minerals — Ferritin and Vitamin D
Sample
4 blood tubes plus 1 urine sample (for the microalbumin check).
Fasting required ★ — please fast for 12 hours before your draw. Critical for accurate insulin, glucose and lipid readings.
Cadence
Run every 3 or 6 months while you're on a GLP-1 programme. Compare each result against your initial Weight Loss Commencement baseline to track real progress.
Analysed in our ISO-accredited UK laboratory.

What we measure
The biomarkers in this panel.
Haematocrit
The proportion of your blood made up of red cells.
Why it matters
Gives a quick snapshot of how oxygen-rich your blood is.
Mean Cell Haemoglobin
The average amount of haemoglobin in each red blood cell.
Why it matters
Helps show whether your red cells are well-stocked with oxygen-carrying protein.
Mean Cell Haemoglobin Concentration
How concentrated the haemoglobin is in your red blood cells.

Another angle on red blood cell quality, useful when looking at iron status.
Mean Cell Volume
The average size of your red blood cells.
Why it matters
Cell size can hint at iron, B12 or folate levels.

The number of red cells in your blood.
Why it matters
Red cells carry oxygen — too few or too many can both be a sign something's off.
Basophil Count
A type of white blood cell.
Why it matters

Lymphocyte Count
Immune-system white blood cells.
Why it matters
Shows how your body is responding to infections or viruses.
Eosinophil Count
A white blood cell linked to allergies and parasites.
Why it matters

The total count of immune cells in your blood.
Why it matters
A general marker of how active your immune system is.
Platelet Count
Tiny cells that help your blood clot.
Why it matters

Total Cholesterol
The total amount of cholesterol in your blood.
Why it matters
A long-standing marker for heart and circulation health.
LDL Cholesterol
The 'less helpful' type of cholesterol.
Why it matters
Higher levels are linked to a greater chance of furred-up arteries over time.
HDL Cholesterol
The 'helpful' type of cholesterol.
Why it matters
Higher levels are generally linked to better heart health.
Total Cholesterol/HDL Cholesterol Ratio
Total cholesterol compared with HDL.
Why it matters
A simple ratio that gives a clearer picture than total cholesterol alone.
Triglycerides
Fats circulating in your blood.
Why it matters
Linked to diet, weight and heart health — often respond well to lifestyle tweaks.
Apolipoprotein B
The main protein in LDL ('less helpful') cholesterol.
Why it matters
Gives a more direct read on artery-clogging particles than LDL alone.
Creatinine
A waste product cleared by your kidneys.
Why it matters
A core marker for how well your kidneys are filtering.
eGFR
An estimate of how well your kidneys are filtering.
Why it matters
A simple summary score for kidney function.

Why it matters
Useful for understanding bone health and overall nutrition.
Chloride
An electrolyte that keeps your body's fluids balanced.
Why it matters
Useful alongside sodium and potassium for hydration and kidney insight.
Magnesium
A mineral involved in energy, sleep and muscle function.
Why it matters
Low levels are linked to fatigue, cramps and poor sleep.
Phosphate
A mineral that works with calcium for bones and energy.

Linked to hydration, blood pressure and kidney health.
Urea
A waste product from breaking down protein.
Why it matters
Another check on kidney filtering and hydration.
Microalbumin / Creatinine Ratio
A urine check comparing albumin to creatinine.
Why it matters
An early indicator of kidney strain — picks things up before standard kidney markers shift.
Alanine Aminotransferase
A liver health marker.
Why it matters
Higher levels can be a sign your liver is under stress, often linked to diet, alcohol, or fatty liver.
Alkaline Phosphatase
A marker linked to both liver and bone health.
Why it matters
Levels can shift when the liver is under strain or when bones are remodelling more than usual.
Aspartate Aminotransferase
Another liver health marker.
Why it matters
Read alongside ALT, it gives extra insight into how your liver and muscles are coping.
Gamma-Glutamyltransferase
A liver marker (often called GGT).
Why it matters
Often raised by alcohol or fatty liver — a useful check-in on lifestyle impact.
Total Bilirubin
A waste product the liver clears from your blood.
Why it matters
Higher levels can be a sign your liver isn't clearing things as efficiently as usual.
Albumin
The main protein in your blood, made by the liver.

Vitamin D
A vitamin you make from sunlight and get from food.
Why it matters
Linked to bone strength, immune function and mood. Many people in the UK run low.

FAQs
Common questions.
How long do Weight Loss Monitoring results take?
Weight Loss Monitoring results are typically delivered within 3 working days of the laboratory receiving your sample. You receive a plain English PDF report.
How is the sample collected for Weight Loss Monitoring?
Weight Loss Monitoring requires a venous blood draw at a Chxhealth or partner clinic. The phlebotomy fee is included in the price. Choose our Lanchester clinic or one of our 50+ UK partner and pop-up clinics when you book.
How often should I monitor during a weight-loss programme?
Typical cadence is every 3 to 6 months, or more frequently around dose changes if you are on weight-loss medication. The panel is designed to be retested over time alongside Weight Loss Commencement as your baseline.
What does Weight Loss Monitoring track?
It covers the biomarkers most relevant to ongoing weight management: lipids, glucose, insulin, liver enzymes, thyroid, and nutritional markers that can shift during sustained weight loss.
Is this panel useful for GLP-1 users?
Yes. The panel covers the markers most often monitored during GLP-1 treatment, so you can track progress alongside the clinician managing your medication. Chxhealth is a biomarker and genetic data provider. We do not diagnose, treat or prescribe. For medical advice, please speak to a qualified healthcare professional.
