Weight-Loss Injection Monitoring Blood Test Panel
What Mounjaro, Ozempic, Wegovy and Retatrutide users should actually be tracking — beyond the scales.
Weight-loss injection monitoring is a blood test panel for people using GLP-1 or GIP medications — Mounjaro (tirzepatide), Ozempic or Wegovy (semaglutide), and Retatrutide — that checks for nutrient deficiencies, muscle loss and organ stress rather than just tracking the number on the scales.
Rapid weight loss from these medications doesn't distinguish between fat and muscle, and reduced appetite often means reduced nutrient intake too. The scales can't show either of those things happening. A blood panel can.
Why monitoring matters on Mounjaro, Ozempic or Wegovy
GLP-1 and GIP receptor agonists work by suppressing appetite — which is exactly why they need watching, not just weighing:
- Muscle loss. A significant share of weight lost on these medications can be lean muscle, not fat, especially without adequate protein intake. The scales can't tell the difference; a full blood count and metabolic markers can flag it earlier.
- Nutrient deficiency. Eating less means absorbing less. Vitamin D, B12 and folate are the markers that typically drop first and are easiest to miss until symptoms (fatigue, brain fog, low mood) are already noticeable.
- Organ stress. Kidney function (creatinine, eGFR, urea) and liver function (ALT, AST, ALP, bilirubin and related markers) can shift under rapid weight loss and reduced intake, and thyroid function is worth tracking given its role in metabolism.
- Blood sugar control. HbA1c tracks longer-term glucose control — relevant both to why many people start these medications and to how their metabolism is responding over time.
None of this shows up on a set of bathroom scales. It only shows up in blood.
What's tested: 42 biomarkers across 7 categories
The Boost & Glow Weight-Loss Injection Monitoring Panel covers every system rapid weight loss can affect:
| Category | Markers | What it tracks |
|---|---|---|
| Full Blood Count (15 markers) | RBC, WBC, Haemoglobin, Haematocrit, MCV, MCH, MCHC, RDW, MPV, white cell differentials | General health, anaemia, immune status — and early signs of muscle/lean mass change |
| Iron Studies (4 markers) | Iron, Ferritin, Transferrin, Transferrin Saturation | Iron deficiency, common when intake drops |
| Kidney Function (4 markers) | Creatinine, eGFR, Urea, Sodium | How the kidneys are coping with rapid weight loss |
| Liver Function (9 markers) | ALT, AST, ALP, Gamma GT, Bilirubin, Albumin, Globulin, Total Protein, LDH | Liver stress and protein status |
| Thyroid Function (5 markers) | TSH, Free T4, Free T3, Thyroglobulin Antibodies, TPO Antibodies | Metabolic regulation |
| Metabolic Health (1 marker) | HbA1c | Longer-term blood sugar control |
| Nutrient Status (3 markers) | Active B12, Folate, Vitamin D | The three deficiencies most likely to develop on reduced intake |
Results come with expert review and personalised recommendations, not just a results sheet.
Who should test, and how often
Anyone currently using Mounjaro, Ozempic, Wegovy, Retatrutide or another GLP-1/GIP medication, for weight loss or for type 2 diabetes management. Testing every 6 months is recommended, with a minimum of once a year — closely enough to catch a deficiency or a kidney/liver marker drifting before it becomes a bigger problem.
How it works: a venous blood draw, available in-clinic in Epping, Essex, or via a mobile appointment across Essex, Hertfordshire and London. The team gets in touch to schedule the appointment after booking.
