Specialist blood tests for patients on Mounjaro, Wegovy and other weight loss treatments. Designed around MHRA monitoring guidance, from our clinic in Longridge, Lancashire.
Weight loss medications like Mounjaro® and Wegovy® are among the most effective treatments available, but like any long-term medication, they affect how your body processes food, regulates hormones and manages waste. Monitoring a small set of key blood markers before and during treatment is the single most effective way to catch any issues early and get the most out of your treatment plan.
At Longridge Travel Health Clinic, we offer three tiered weight loss blood test profiles designed to give you and your clinician the information you need, from a simple baseline check before your first injection, right through to advanced monitoring for patients on higher doses. All three tests are processed by our UK laboratory partners with results typically back within 1 working day.
GLP-1 medications work by acting on the pancreas, digestive system and appetite-regulating areas of the brain. Because they affect so many systems at once, a handful of blood markers can reveal how well your body is coping with treatment and whether your dose needs to be adjusted.
Pancreatitis is a rare but recognised risk of GLP-1 treatment. Lipase and amylase are the two enzymes that reveal pancreatic inflammation early, often before symptoms become severe.
An underactive thyroid can be a hidden reason weight loss stalls. On higher doses and longer treatment courses, vitamin D, B12 and iron status also matter - deficiencies here are a common cause of fatigue that can easily be mistaken for a side effect.
HbA1c shows how your long-term blood sugar is responding to treatment, and a full lipid profile reveals whether your cardiovascular risk is improving as you lose weight.
Rapid weight loss, changes in diet, and the medication itself can all place extra demand on your liver and kidneys. ALT, AST, GGT, creatinine and eGFR are the key markers.
Every test is processed by our UK lab partners with a 3-day turnaround and includes a clinical review of your results.

This is general guidance - your clinician will tailor the exact schedule based on your dose, health history, and how you’re tolerating treatment.
| Stage | When | Recommended Test | Why |
|---|---|---|---|
| Baseline | Before your first injection | Essential £119 | Establishes a health reference point and screens for any issues that would change your treatment plan. |
| Dose escalation | Weeks 4–8 (first dose increase) | Essential £119 | Confirms your liver, kidney and pancreas are tolerating the higher dose. |
| 12-week review | Month 3 of treatment | Advanced £189 | Gives a full picture once you’re settled on a maintenance dose - catches any nutritional deficiencies and confirms progress. |
| Ongoing | Every 3–6 months on maintenance | Essential or + Thyroid | Routine monitoring to keep your treatment safe long-term. |
These tests aren’t just for patients on Mounjaro or Wegovy. They’re equally useful if you’re making significant lifestyle changes, starting an intensive fitness programme, or simply want to understand why weight loss has been difficult despite doing “the right things”. A blood test will often reveal things a scale cannot - underactive thyroid, insulin resistance, iron deficiency, or Vitamin D deficiency are all common contributors to stubborn weight and low energy.
