Support safe and effective weight loss with our GLP-1 Plus Weight Management Profile – At-Home Blood Test. Designed for individuals using or considering GLP-1 medications (such as Ozempic®, Wegovy®, Mounjaro®) or following structured weight-management programmes, this enhanced panel builds on the core safety markers by adding Vitamin B12, Vitamin D and Leptin to assess nutrient status, metabolic health and treatment response. This advanced profile measures: Blood Sugar & Metabolism: HbA1c Liver & Pancreatic Health: ALT, AST, GGT, Bilirubin, Amylase, Lipase Kidney Function: Urea, Creatinine, Uric Acid, eGFR Thyroid Balance: TSH, Free T4 (FT4) Cardiovascular Lipids: Total Cholesterol, HDL, LDL, Triglycerides Nutrient Status & Appetite Regulation: Vitamin B12, Vitamin D (25-OH), Leptin Blood Health: Full Blood Count (FBC) Ideal for individuals seeking more comprehensive monitoring of GLP-1 therapy, this test provides insight into treatment safety, nutrient reserves, appetite signalling, metabolic improvements, and potential side-effects — helping you and your clinician optimise results and protect long-term health.
GLP-1 medications such as semaglutide, liraglutide, and tirzepatide (commonly known as Ozempic®, Wegovy® and Mounjaro®) are transforming weight loss and type 2 diabetes care by influencing appetite control, glucose regulation, and metabolic rate. Alongside intensive weight-loss programmes, however, these rapid changes can also affect nutrient status, organ function, and overall metabolic balance.
The Weight Loss / GLP-1 Plus Profile from Vitalync Diagnosis expands on our standard GLP-1 panel by adding Vitamin B12, Vitamin D and Leptin, offering a more comprehensive view of nutrient sufficiency, appetite signalling and your body’s metabolic response to treatment.
Vitamin B12 — Essential for energy, neurological function and red blood cell production; levels may fall with restricted intake, gut issues or certain medications.
Vitamin D (25-OH) — Key for immunity, bone strength, mood and metabolic health; deficiency is common during rapid weight change.
Leptin — A hormone involved in appetite regulation and fat metabolism; abnormal levels may reflect metabolic resistance or adaptation during weight loss.
HbA1c — Measures average blood glucose over 2–3 months to monitor diabetes risk and treatment effectiveness.
ALT, AST, GGT, Total Bilirubin — Monitor liver stress, inflammation or bile flow changes.
Amylase, Lipase — Pancreatic enzymes; raised levels may indicate irritation or inflammation.
Urea, Creatinine, Uric Acid, eGFR — Assess kidney function to ensure GLP-1 therapy and weight loss are well tolerated.
TSH, Free T4 (FT4) — Thyroid balance influences weight regulation, mood, energy levels and metabolic rate.
Total Cholesterol, HDL, LDL, Triglycerides — Track cardiometabolic risk factors as weight and metabolic markers change.
Full Blood Count (FBC) — Screens for anaemia, infection or inflammation affecting energy, immunity and overall wellbeing.
This enhanced GLP-1 blood test is ideal for:
Individuals using or about to start GLP-1 medications for weight loss or type 2 diabetes
People experiencing rapid weight change, fatigue or suspected nutrient deficiencies
Those managing obesity, pre-diabetes, metabolic syndrome or insulin resistance
Anyone seeking a comprehensive, medically guided weight-loss health check

Confirm response to GLP-1 therapy
Detect Vitamin B12 or Vitamin D deficiencies early
Understand appetite hormone (Leptin) signalling and metabolic adaptation
Monitor liver, kidney, pancreas and cardiovascular health
Tailor medication, nutrition and lifestyle changes for safer, sustainable results
