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. Our tests help you uncover the hidden drivers of weight and metabolic health so you can take a targeted, informed approach. Starting or using GLP-1 medication? See the important tests to get before and during GLP-1 treatment. Order online, no GP referral needed.

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 fasting insulin, glucose and HbA1c, the core markers for assessing blood sugar control and metabolic health.
Test fasting insulin and glucose levels — key markers your GP may use when assessing metabolic health.
Simple HbA1c blood test measuring average blood sugar levels over the past 3 months.
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 thyroid, cortisol and sex hormones. Read 8 signs your thyroid may be the problem, and our guide to recognising the signs of hormone imbalance.
Measure leptin, the appetite and metabolism hormone, to assess if leptin resistance is driving weight gain.
Measure TSH, free T3 and free T4 — the core markers for understanding your thyroid levels.
Our most complete thyroid panel: TSH, free T3, free T4, reverse T3 plus three thyroid antibodies for a full picture.
Measure oestrogen, progesterone, testosterone, thyroid and cortisol — key markers relevant to hormonal health.
Measure testosterone, cortisol, thyroid, DHEA-S and insulin — key markers relevant to 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 energy. These tests identify deficiencies that may be holding your metabolism back.
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.
Using GLP-1 weight-loss medication?
If you're starting or using GLP-1 medications (Ozempic, Wegovy, Mounjaro), we have a dedicated home for baseline and follow-up monitoring - covering metabolic, liver, kidney and nutritional markers before and during treatment. See our GLP-1 & weight-loss medication monitoring.
A baseline blood panel covering metabolic, liver and kidney markers your prescriber may wish to review before you commence a GLP-1 receptor agonist medication.
A blood panel of nutritional and organ-function markers you and your prescribing doctor may choose to review during treatment with a GLP-1 receptor agonist medication.
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 blood sugar, insulin, inflammation, hormones, nutrients and organ function in one order - ideal for a thorough baseline or a structured weight-management plan.
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.
