Metabolic Health

The Phosphate Blood Test measures phosphate, an essential mineral and electrolyte that supports strong bones, energy production, and muscle and nerve function. Abnormal levels may suggest problems with kidneys, hormones, or nutrition.

The Potassium Blood Test measures potassium, a mineral and electrolyte that helps control muscle movement, nerve signals, and heart rhythm. Abnormal levels may suggest kidney problems, hormone imbalances, or issues with diet and medications.

The Progesterone Test measures levels of progesterone, a hormone important for menstrual cycles, fertility, and maintaining pregnancy. In women, levels change during the cycle and rise after ovulation. This test may help assess fertility, ovulation, or hormone balance, and in pregnancy it may help monitor placenta and fetal health.

This test measures levels of prolactin, a hormone made by the pituitary gland. Prolactin is important for fertility, sexual health, and milk production in women. Abnormal levels may suggest hormone imbalances that affect periods, fertility, or sexual function. In some cases, very high prolactin can be linked to growths in the pituitary gland (usually benign), so this test may help guide whether further checks are needed.

The Red Blood Cell Copper Blood Test measures copper stored inside red blood cells, giving a clearer view of long-term copper status than a standard blood test. Copper is essential for energy, immunity, and red blood cell production. Low levels may cause fatigue, anaemia, or weak immunity, while high levels may indicate toxicity or over-supplementation.

This test is only available at Healius collection centres.

The Red Blood Cell Magnesium Blood Test measures magnesium stored inside red blood cells, giving a more accurate picture of long-term magnesium status than a standard blood test. Magnesium is vital for energy, muscle function, heart rhythm, and nerve health. Low levels may cause cramps, fatigue, or heart problems.

This test is only available at Healius collection centres.

The Red Blood Cell Zinc Test measures zinc stored inside red blood cells, giving a more accurate picture of long-term zinc status than standard blood zinc tests. Adequate zinc supports immunity, hormone balance, metabolism, and healing, while low levels may lead to fatigue, poor immunity, and reproductive issues.

This test is only available at Healius collection centres.

The Reverse T3 (rT3) Test measures a form of thyroid hormone that is inactive. High rT3 levels may happen during stress, illness, or inflammation when the body slows metabolism. This test may help give a broader picture of thyroid and metabolic function alongside a Thyroid Function Tests (TSH, T3, and T4).

The Sex Hormone Binding Globulin (SHBG) Test measures the protein that binds to hormones like testosterone and oestrogen in the blood. SHBG levels affect how much free, active hormone is available, and this test may help assess hormone balance, fertility, and metabolic health.

The Sodium Blood Test measures the level of sodium, an electrolyte that helps control fluid balance, blood pressure, and muscle and nerve function. Abnormal levels may suggest dehydration, kidney problems, or issues with hormone balance.

Want a clear picture of your hormone balance? Testosterone is vital for energy, muscle mass, libido, and overall health in both men and women. This LCMS test gives highly accurate results and may help assess fertility, sexual health, and hormone-related symptoms. For men on testosterone or performance therapies, LCMS testing is especially important, as it provides reliable readings even when testosterone levels are higher than normal.

This test checks testosterone in detail – total, free, and bioavailable – plus SHBG and the Free Androgen Index. It may help assess fertility, energy, mood, muscle health, and hormone balance in men and women.

The Thyroid Function Test checks how well your thyroid gland is working by measuring three key hormones: TSH, Free T3, and Free T4. These hormones control energy, metabolism, and growth. Abnormal results can explain symptoms like fatigue, weight changes, mood shifts, or temperature sensitivity, and may indicate an underactive or overactive thyroid.

The Total Protein Blood Test measures the amount of protein in your blood, including albumin and globulins. Proteins are important for building and repairing tissues, fighting infections, and maintaining fluid balance. Abnormal levels can signal liver or kidney problems, nutritional issues, or immune disorders.

The Triglycerides Blood Test measures the level of fats (triglycerides) in your blood. High levels can increase the risk of heart disease, stroke, and pancreatitis, and are often linked to diet, weight, and diabetes. Healthy levels support good heart and metabolic health.

The Urate (Uric Acid) Blood Test measures the level of uric acid in your blood. High levels can cause crystals to form in the joints, leading to gout, and may also signal kidney problems or higher risk of heart disease. Low levels are less common but can happen with certain conditions or medications.

The Urea Blood Test checks how much urea, a waste product made when the body breaks down protein, is in your blood. High or low levels can point to kidney problems, dehydration, or liver issues, and the test is often used alongside other markers to assess overall kidney and metabolic function.

The Vitamin B1 (Thiamine) Blood Test measures levels of thiamine, a vitamin that helps your body convert food into energy and supports nerve and heart function. Low B1 can cause fatigue, muscle weakness, nerve problems, and in severe cases heart complications. Adequate levels are important for energy and overall health.

The Vitamin B12 Blood Test measures levels of B12 (Cobalamin), a vitamin essential for making red blood cells, protecting nerves, and supporting energy production. Low B12 can cause fatigue, anaemia, memory issues, and nerve problems, while healthy levels are vital for brain function and overall wellbeing.

The Vitamin B2 (Riboflavin) Blood Test measures levels of riboflavin, a vitamin that helps your body turn food into energy and supports healthy red blood cells. Low B2 can cause fatigue, mouth sores, cracked lips, and increase the risk of anaemia, while good levels help maintain energy and overall health.

The Vitamin B6 Blood Test measures levels of pyridoxine, a B-vitamin that helps your body process protein, make red blood cells, and keep the nervous system working properly. Low B6 can cause anaemia, irritability, confusion, or nerve problems, while healthy levels support energy, brain health, and overall wellbeing.

The Vitamin B9 (Folate) Blood Test measures levels of folate, a B-vitamin that helps make red blood cells and supports DNA and cell growth. Low folate can cause anaemia, fatigue, and in pregnancy increase the risk of birth defects, while healthy levels support energy, metabolism, and overall wellbeing.
