Blood tests your doctor needs to run

• ✅
  HbA1c — your 3-month average blood sugar (key for NHS eligibility)
• ✅
  Fasting glucose — single blood sugar reading taken after fasting
• ✅
  eGFR (kidney function) — Mounjaro not suitable if severely reduced
• ✅
  LFTs (liver function) — routine baseline check
• ✅
  BMI — height and weight measured by your GP
• ✅
  TSH (thyroid function) — Mounjaro not suitable with certain thyroid conditions
• ✅
  Full blood count — baseline check before starting treatment

📋 Most Mounjaro providers will require recent blood test results (typically within 3–6 months). Getting tested privately means faster access to treatment — results in 24–48 hours rather than waiting weeks for an NHS appointment.
