What Does This Test Check?
Weight is only one way to monitor your progress. This panel measures a broad range of health markers that can provide additional information during ongoing weight management.
It assesses blood sugar control and insulin resistance alongside cholesterol, liver, kidney, pancreatic, thyroid, hormonal, inflammatory and nutritional markers.
This can provide useful information while you are receiving prescribed weight loss treatment, including Mounjaro (tirzepatide), Wegovy (semaglutide) or other clinician-led weight management treatment.
The test does not measure how much Mounjaro or Wegovy is in your body. It also does not directly determine whether a medicine is working. Weight changes, treatment response and clinical assessment remain important.
What's Included?
The panel groups related markers together to provide a broad view of your health during weight management.
Blood Sugar and Insulin Resistance
Glucose
Measures the amount of glucose in your blood at the time of testing.
HbA1c
Provides information about average blood glucose levels over recent months.
Insulin
Measures insulin, the hormone involved in regulating blood glucose.
HOMA-IR
Provides an estimate of insulin resistance using glucose and insulin measurements.
Cholesterol and Cardiovascular Health
Total Cholesterol
Measures the overall amount of cholesterol in your blood.
LDL Cholesterol
Measures low-density lipoprotein cholesterol.
HDL Cholesterol
Measures high-density lipoprotein cholesterol.
Triglycerides
Measures an important type of fat found in the blood.
Total Cholesterol/HDL Ratio
Provides additional context when assessing your cholesterol profile.
Apolipoprotein B (ApoB)
Provides additional information about atherogenic lipoprotein particles.
Liver Health
ALT
A liver enzyme used as part of liver health assessment.
AST
An enzyme considered alongside other liver markers.
ALP
An enzyme that can provide information relating to the liver and other tissues.
GGT
A liver-related enzyme used alongside other markers when assessing liver health.
Total Bilirubin
Measures bilirubin in the blood and forms part of a broader liver assessment.
Albumin
Measures an important protein produced by the liver.
Kidney Health
Creatinine
Measures a waste product used when assessing kidney function.
eGFR
Provides an estimate of how effectively the kidneys are filtering the blood.
Urea
Provides additional information used when assessing kidney function and general health.
Urine Albumin-to-Creatinine Ratio
Uses a urine sample to assess the amount of albumin relative to creatinine.
Pancreatic Enzymes
Lipase
Measures an enzyme produced mainly by the pancreas.
Pancreatic Amylase
Measures an enzyme associated with pancreatic function.
Pancreatic enzyme results require clinical context. These measurements do not independently rule out pancreatic disease and should not delay medical assessment of concerning symptoms.
Thyroid Health
TSH
Thyroid-stimulating hormone helps regulate thyroid hormone production.
Free T4
Measures circulating free thyroxine and is interpreted alongside TSH when assessing thyroid function.
Hormone Health
Testosterone
Measures circulating testosterone.
Oestradiol
Measures an important form of oestrogen.
SHBG
Sex hormone-binding globulin binds sex hormones and helps provide context when interpreting testosterone.
Free Androgen Index
Provides an estimate of available androgen activity using testosterone and SHBG measurements.
FSH
Follicle-stimulating hormone is involved in reproductive hormone signalling.
LH
Luteinising hormone is involved in reproductive hormone regulation.
Prolactin
Measures a hormone produced by the pituitary gland.
Blood and Iron Health
Full Blood Count
Measures important components of the blood, including red blood cells, white blood cells and platelets.
Ferritin
Provides information about stored iron.
Vitamins, Minerals and Bone Health
Vitamin D
Measures vitamin D status.
Magnesium
Measures an important mineral involved in many normal body functions.
Adjusted Calcium
Provides a calcium measurement adjusted for albumin.
Phosphate
Measures phosphate, an important mineral involved in bone and cellular health.
Electrolytes
Sodium
Measures an important electrolyte involved in fluid balance and normal body function.
Potassium
Measures an electrolyte important for normal nerve, muscle and heart function.
Chloride
Measures an electrolyte involved in fluid and acid-base balance.
Inflammation
High-Sensitivity C-Reactive Protein (hsCRP)
Measures low levels of C-reactive protein as a marker of systemic inflammation. The result should be interpreted alongside other health information.
