Blood Testing in Sydney

Simple iron test to measure iron levels in blood and body stores.

Measures TSH and thyroid hormones to assess thyroid function. Helps detect hypothyroidism and hyperthyroidism.

Measures morning serum cortisol — the primary stress hormone produced by the adrenal glands. Cortisol follows a strong circadian rhythm, peaking within 30 minutes of waking and declining through the day. Chronically elevated cortisol drives weight gain (particularly visceral fat), disrupts sleep architecture, suppresses immune function, and accelerates muscle loss. Chronically low cortisol suggests adrenal insufficiency or HPA axis exhaustion from prolonged stress.

Measures hormone levels to assess endocrine function and overall hormonal balance.

Comprehensive blood test to assess insulin resistance and its associated health risks.

Simple thyroid test to determine if your thyroid is over or underactive.

Urine PCR test for three common STIs: Chlamydia, Gonorrhea, and Trichomonas.

Measures your average blood glucose levels over the past 2-3 months using glycated haemoglobin — a more reliable indicator of metabolic health than a single fasting glucose reading. HbA1c is the gold standard for diagnosing and monitoring diabetes, but it is equally valuable for detecting pre-diabetes at a stage when lifestyle changes can reverse the trajectory. Approximately 1.5 million Australians have diabetes, with many more undiagnosed.

Measures 25-hydroxyvitamin D — the circulating form your body uses for bone health, immune function, mood regulation, and muscle performance. Vitamin D deficiency affects up to 1 in 4 Australian adults despite abundant sunshine, driven by indoor lifestyles, sunscreen use, and darker skin tones. This affordable single-marker test provides the data point that informs whether supplementation is needed and at what dose.

A targeted 15-marker panel measuring total testosterone, free testosterone, SHBG, and LH — the four markers needed to properly assess whether testosterone is genuinely low and where the problem originates. Total testosterone alone is insufficient because SHBG binds testosterone and makes it unavailable to tissues. Free testosterone and the total-to-SHBG ratio reveal what your body can actually use.

Comprehensive sperm test to assess male fertility.

An entry-level hormone screen measuring 15 markers including LH, FSH, oestradiol, testosterone, cortisol, and TSH — the core hormones that govern energy, mood, libido, weight, and sleep. Provides a broad hormonal overview at an accessible price point, suitable for both men and women wanting to investigate whether hormonal disruption is behind their symptoms before committing to a comprehensive panel.

A 15-marker panel combining HbA1c, fasting glucose, and fasting insulin — the three markers that together provide a complete picture of blood sugar regulation. HbA1c shows your 3-month average, fasting glucose reflects immediate control, and fasting insulin reveals whether your pancreas is overworking to maintain normal glucose levels. More comprehensive than HbA1c alone and far more informative than the standard GP glucose test.

Blood test to detect Ross River virus infection.

Basic health screening with full blood count (FBC), ESR, liver function, kidney function, lipid profile, fasting glucose, magnesium, and CRP. Ideal first health check.

iMEDICAL's standard health check adds a full blood count with ESR to the comprehensive metabolic panel, providing a complete overview of blood cell health alongside metabolic, liver, kidney, lipid, and inflammation markers. The FBC reveals red and white blood cell counts, haemoglobin, platelets, and ESR — useful for detecting anaemia, infection, and inflammatory conditions.

Core STD blood screening: HIV (4th gen ELISA), Hepatitis B surface antigen, Hepatitis C antibody. Results in 24-48 hours.

Measures homocysteine — an amino acid that at elevated levels is an independent risk factor for cardiovascular disease, stroke, cognitive decline, and accelerated ageing. Homocysteine is a direct marker of methylation efficiency, the biochemical process responsible for DNA repair, neurotransmitter production, and detoxification. Elevated levels indicate impaired B12, folate, or B6 metabolism and are modifiable through targeted supplementation.

Blood test measuring cortisol and DHEA-S to assess adrenal function and hormone balance.

Oral glucose tolerance test measuring glucose and insulin levels.

Measures hormone levels to assess endocrine function and overall hormonal balance.

Measures hormone levels to assess endocrine function and overall hormonal balance.

Measures hormone levels to assess endocrine function and overall hormonal balance.

Measures IGF-1 — the primary mediator of growth hormone's effects on tissues. IGF-1 reflects your average growth hormone status (GH itself is pulsatile and difficult to measure accurately) and influences muscle maintenance, fat metabolism, bone density, and cellular repair. In longevity research, IGF-1 occupies a nuanced position — too low impairs tissue repair and muscle mass, too high is associated with accelerated ageing and cancer risk.
