Support Healthy Weight, Metabolism & Blood Sugar
Maintaining a healthy weight depends on far more than calories. Hormones, blood sugar control, nutrient levels and metabolic function all play a major role in how your body stores fat, burns energy and responds to diet or exercise. Our metabolism blood tests, blood sugar tests, and weight loss blood test options help you uncover the underlying factors affecting your weight, cravings, energy and metabolic health. Whether you’re struggling with insulin resistance, hormonal imbalances, slow metabolism or are beginning GLP-1 medications, these tests give you clear, personalised insights to optimise your results safely. If you’re starting or currently using Ozempic, Wegovy or Mounjaro, read our guide on important tests to get before and during GLP-1 treatment.

Want the most comprehensive test for metabolism, weight control & blood sugar?
If you want the fullest picture of your metabolic health, these complete metabolism panels assess hormones, insulin, glucose tolerance, nutrients, inflammation and energy production. They provide the most advanced insight into the biological drivers behind weight gain, slow metabolism and fatigue.
A full metabolic snapshot covering blood sugar, insulin, inflammation, hormones, nutrients and organ function in one panel.
Blood test plus dietitian consult identifying hormonal, metabolic and nutritional blocks to weight loss.
Comprehensive blood and urine analysis of minerals, fatty acids, amino acids, organic acids and metabolic health markers.
Deep insights into cardiovascular, hormonal, nutritional and gut health across 117 biomarkers in one blood test.
Deep insights into cardiovascular, hormonal, nutritional and gut health across 117 biomarkers in one women's blood test.
Is insulin resistance making weight loss harder?
Insulin resistance is one of the most common, and overlooked, causes of weight gain, cravings, fatigue and difficulty losing weight. These tests measure glucose control, fasting insulin and long-term blood sugar patterns.
Test fasting insulin and glucose levels to detect insulin resistance early, before it progresses to type 2 diabetes.
Simple HbA1c blood test measuring average blood sugar over 3 months to screen for diabetes or pre-diabetes.
Glucose and insulin measured at intervals after a glucose drink to assess how your body processes sugar.
Are your hormones influencing weight changes?
Hormonal imbalances can affect appetite, metabolism, fat storage and energy levels. These tests assess key hormones linked to weight management including thyroid hormones, cortisol and leptin. An underactive thyroid is one of the most common causes of unexplained weight gain — read 8 signs your thyroid may be the problem. If you suspect a broader hormone imbalance, our guide to recognising the signs of hormone imbalance can help you understand where to start.
Measure leptin, the appetite and metabolism hormone, to assess if leptin resistance is driving weight gain.
Measure TSH, free T3 and free T4 to check if your thyroid is behind fatigue, weight changes or low mood.
Our most complete thyroid panel: TSH, free T3, free T4, reverse T3 plus three thyroid antibodies for a full picture.
Saliva test mapping your morning cortisol spike and daily rhythm to assess stress response and HPA axis function.
Dried urine test mapping cortisol patterns, oestrogen, progesterone, testosterone and their metabolites across a full day.
Measure oestrogen, progesterone, testosterone, thyroid and cortisol to identify hormonal imbalances affecting your wellbeing.
Measure testosterone, cortisol, thyroid, DHEA and insulin to identify hormonal imbalances affecting energy and wellbeing.
Is nutrient deficiency slowing your metabolism?
Low levels of B vitamins, iron, vitamin D and essential micronutrients can reduce metabolic rate and impair weight loss. These tests reveal deficiencies that may be impacting energy production and fat metabolism.
Screen 27 vitamins and minerals including zinc, selenium, magnesium, B vitamins and antioxidants in one panel.
Test B12, folate and active B12 - key markers for anaemia, energy, mood and methylation health.
Check your iron, ferritin and transferrin levels. Iron deficiency is Australia’s most common nutritional problem.
Check your vitamin D level - over 30% of Australian adults are deficient, causing fatigue and muscle weakness.
This test includes 26 essential and non essential amino acids. Testing amino acids helps assess nutritional status, metabolic function, and potential deficiencies or imbalances that may impact energy, mood, detoxification, and overall health.
Are you using GLP-1 medications and want to monitor your safety & progress?
If you're starting or currently using GLP-1 medications (like Ozempic, Wegovy or Mounjaro), these targeted panels assess your baseline metabolic health and how well your body is responding over time — helping ensure safe and effective results.
A comprehensive blood panel to assess your baseline health and make sure you're ready to start a GLP-1 medication like Ozempic, Wegovy, or Mounjaro safely and effectively.
Stay on top of your progress with this tailored blood test, designed to monitor how your body is responding to GLP-1 medications and catch any nutrient gaps or adverse effects early.
