Biomarkers

What Your Blood Can Tell You

Biomarkers are measurable indicators found in your blood that provide insight into how your body is functioning. From cholesterol and hormones to vitamins and inflammation markers, these tests help reveal patterns that influence energy, metabolism, and long-term health.

Health Categories
Serum Calcium
Calcium is an essential mineral for bone formation, muscle contraction, nerve signalling, and heart function. It is closely regulated by parathyroid hormone and vitamin D.
Nutrients & Vitamins
Serum Cortisol
Cortisol is produced by the adrenal glands and regulates the body’s stress response, metabolism, inflammation, and immune function. Levels are highest in the morning.
Hormone Health
Creatine Kinase
Creatine kinase is an enzyme found in skeletal muscle, heart muscle, and brain tissue. It is released into the blood when muscle cells are damaged.
Inflammation
Dehydroepiandrosterone Sulphate
DHEA-S is a hormone produced by the adrenal glands that serves as a precursor to both testosterone and oestrogen. Levels decline steadily with age.
Hormone Health
Free Testosterone
Free testosterone is the unbound, biologically active form of testosterone that is available for the body to use directly.
Hormone Health
Follicle-Stimulating Hormone
Follicle-stimulating hormone is produced by the pituitary gland and plays a central role in reproductive health by stimulating egg and sperm development.
Hormone Health
Luteinising Hormone
Luteinising hormone is produced by the pituitary gland and triggers ovulation in women and testosterone production in men.
Hormone Health
Lipoprotein(a)
Lipoprotein(a) is a type of lipoprotein particle that carries cholesterol and promotes clot formation. Levels are largely determined by genetics.
Cardiovascular Health
Serum Magnesium
Magnesium is a mineral essential for muscle and nerve function, blood sugar regulation, blood pressure control, and energy production.
Nutrients & Vitamins
Oestradiol (E2)
Oestradiol is the most potent and prevalent form of oestrogen. It plays a central role in the menstrual cycle, bone health, and cardiovascular function.
Hormone Health
Serum Phosphate
Phosphate is an essential mineral for bone structure, energy metabolism, and cell function. It is closely regulated alongside calcium by the kidneys.
Kidney Function, Nutrients & Vitamins
Platelet Count
Platelets are small blood cells that help the body form clots to stop bleeding. The platelet count reflects bone marrow production and platelet consumption.
Blood & Oxygen Transport, Immune & Infection
Serum Potassium
Potassium is an electrolyte essential for maintaining normal heart rhythm, nerve signalling, and muscle contraction. It is tightly regulated by the kidneys.
Kidney Function
Serum Prolactin
Prolactin is a hormone produced by the pituitary gland. It is best known for stimulating milk production but also plays roles in reproductive and immune function.
Hormone Health
Sex Hormone-Binding Globulin
SHBG is a protein produced by the liver that binds sex hormones and regulates how much free hormone is available for the body to use.
Hormone Health
Serum Sodium
Sodium is an essential electrolyte that helps regulate fluid balance, blood pressure, and nerve and muscle function throughout the body.
Kidney Function
Anti-Thyroid Peroxidase Antibodies
TPO antibodies are autoimmune markers that attack the thyroid gland. Their presence suggests the immune system is targeting thyroid tissue.
Immune & Infection, Thyroid Function
Total Serum Protein
Total protein measures all proteins in the blood, primarily albumin and globulins. It reflects liver synthetic function and overall protein balance.
Immune & Infection, Liver Health
White Blood Cell Count
White blood cells are the body’s primary defence against infection. The total count helps assess immune function and detect active infection or inflammation.
