44+ biomarkers.
One clear picture.

Drives muscle growth, fat metabolism, libido, mood, and competitive drive. The most requested marker by men — and one of the most misunderstood.

The biologically active fraction of testosterone. Total testosterone can look normal while free testosterone is low — this is the number that actually matters.

Sex Hormone Binding Globulin. High SHBG binds testosterone and reduces how much is actually available to your cells. Critical for interpreting testosterone results accurately.

The primary oestrogen. Measured in both men and women — in men, elevated oestradiol from testosterone aromatisation can cause fatigue, water retention, and mood changes.

Luteinising Hormone. Signals the testes or ovaries to produce testosterone. Low LH with low testosterone points to a pituitary issue rather than primary gonadal failure.

Follicle-Stimulating Hormone. Works alongside LH to regulate reproductive function. In women, FSH levels are a key indicator of ovarian reserve.

Dehydroepiandrosterone sulphate — a precursor to both testosterone and oestrogen, produced by the adrenal glands. Declines with age; low levels are associated with fatigue and reduced resilience.

A key female reproductive hormone, also present at low levels in men. In women, it counterbalances oestrogen and is essential for cycle regularity and mood stability.

Elevated prolactin suppresses testosterone and can cause libido loss, infertility, and fatigue. Commonly overlooked on standard panels.

Thyroid-Stimulating Hormone. The primary screening marker for thyroid function. Elevated TSH indicates your thyroid is underperforming — even if still in the "normal" range.

The storage form of thyroid hormone. Used alongside TSH to distinguish between primary thyroid dysfunction and conversion problems.

The active form of thyroid hormone. Some people convert T4 poorly — normal TSH and T4 with low free T3 explains persistent fatigue that standard thyroid tests miss.

Blood sugar measured after an overnight fast. Elevated fasting glucose is the earliest measurable sign of insulin resistance — often present years before pre-diabetes is diagnosed.

A 3-month average of blood sugar levels. More informative than a single glucose reading — shows your blood sugar trend over time rather than just a snapshot.

The most sensitive early marker of insulin resistance. Glucose can appear normal for years while insulin is already chronically elevated — this is what catches it early.

A broad marker that tells an incomplete story alone — must be interpreted alongside LDL, HDL, and triglycerides for meaningful cardiovascular risk assessment.

Low-density lipoprotein — the primary driver of atherosclerosis when chronically elevated. The most important lipid marker for long-term heart disease risk.

High-density lipoprotein — the "protective" cholesterol that transports LDL back to the liver. Higher is better. Low HDL combined with high triglycerides is a strong risk signal.

Blood fats that rise sharply with sugar intake, alcohol, and refined carbohydrates. Elevated triglycerides are a direct marker of metabolic dysfunction.

High-sensitivity C-Reactive Protein. A marker of systemic inflammation. Chronically elevated hsCRP predicts cardiovascular disease, metabolic dysfunction, and poor recovery from training.

The protein in red blood cells that carries oxygen. Directly determines aerobic capacity. Low haemoglobin is the clearest driver of unexplained fatigue and poor endurance performance.

Your iron storage marker. Depleted ferritin causes fatigue, brain fog, and reduced exercise tolerance — often months before full iron-deficiency anaemia develops. One of the most commonly undertreated deficiencies in athletes.

The total count of immune cells. Chronically low WBC can indicate immune suppression from overtraining. Elevated counts can signal infection or inflammatory conditions.

Blood cells involved in clotting. Both very low and very high platelet counts carry clinical significance and warrant investigation.

The amount of iron circulating in the blood. Interpreted alongside ferritin and transferrin saturation to build a complete picture of iron status.

The percentage of iron-carrying protein (transferrin) that is bound to iron. Low saturation confirms iron deficiency; high saturation can indicate iron overload (haemochromatosis).

More hormone than vitamin — Vitamin D receptors are found in almost every tissue in the body. Deficiency is linked to fatigue, immune dysfunction, low testosterone, and reduced muscle function. Over 30% of Australians are deficient.

Essential for energy metabolism, nerve function, and red blood cell production. Deficiency causes fatigue, brain fog, and peripheral neuropathy — particularly common in plant-based dieters.

B-vitamin essential for DNA synthesis and red blood cell production. Low folate can cause megaloblastic anaemia and elevated homocysteine — a cardiovascular risk marker.

Involved in over 300 enzymatic reactions including energy production, muscle contraction, and sleep regulation. Depleted rapidly by exercise, stress, and alcohol — the most under-tested mineral.

Essential for testosterone production, immune function, and wound healing. Zinc deficiency is common in athletes due to sweat losses and can suppress testosterone significantly.

Alanine aminotransferase — the most liver-specific enzyme. Elevated ALT indicates hepatocyte damage from fatty liver disease, alcohol, or medication. Can also transiently rise after intense exercise.

Aspartate aminotransferase — found in liver and muscle. The AST:ALT ratio is used to differentiate liver damage from exercise-induced muscle breakdown.

Gamma-glutamyl transferase — elevated by alcohol, fatty liver, and bile duct issues. A sensitive early marker of liver stress, often rising before other liver enzymes.

The main protein made by the liver. Low albumin reflects chronic liver dysfunction or malnutrition — a sensitive indicator of overall liver synthetic capacity.

Total serum protein. Low levels can indicate poor dietary protein intake, liver dysfunction, or protein-losing conditions.

A breakdown product of haemoglobin. Elevated bilirubin causes jaundice and signals liver dysfunction or accelerated red blood cell destruction.

Alkaline phosphatase — elevated in bile duct obstruction, bone disease, and liver conditions. Interpreted alongside other liver enzymes to narrow the diagnosis.

Estimated Glomerular Filtration Rate — the gold-standard measure of kidney filtering capacity. Declining eGFR over time is the most reliable early indicator of chronic kidney disease.

A muscle metabolism waste product cleared by the kidneys. Elevated creatinine indicates reduced kidney clearance — though high muscle mass can raise creatinine without kidney disease.

Chronically elevated uric acid causes gout and is increasingly linked to metabolic syndrome, hypertension, and kidney disease — especially in high-protein dieters and athletes with large muscle turnover.

The primary stress hormone. Chronically elevated cortisol drives fat storage, muscle breakdown, sleep disruption, and suppressed testosterone. Measured in the morning (8–9am) when naturally at its peak.

Insulin-like Growth Factor 1 — the primary mediator of growth hormone action. IGF-1 drives muscle protein synthesis and recovery. Low IGF-1 limits training adaptation regardless of how hard you train.

Prostate-Specific Antigen. The primary screening marker for prostate health. Recommended for men over 40 as part of annual monitoring — catching changes early dramatically improves outcomes.
