Hormones

Concerned about your calcium levels or bone strength? Parathyroid hormone keeps calcium, phosphate, and vitamin D in balance so your bones, muscles, and nerves work the way they should. This test may help check if your parathyroid glands are doing their job and can be useful if you’re experiencing low bone density, kidney stones, or unexplained muscle weakness.

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 Prostate Specific Antigen (PSA) Blood Test measures the level of PSA, a protein made by the prostate gland. Higher levels may suggest prostate enlargement, inflammation, or cancer, though they can also rise with age or other prostate conditions. This test may help monitor prostate health and support early detection of problems.

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.

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.

Assess your hormonal vitality with our comprehensive Testosterone Blood Test. Whether you're experiencing low energy, reduced muscle mass, or changes in libido, this test measures your total testosterone levels to help identify hormonal imbalances affecting your overall well-being and quality of life.

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 Thyroglobulin Blood Test measures a protein made by the thyroid gland. After thyroid surgery or treatment for thyroid cancer, this test may help check for recurrence. It can also be used alongside antibody tests to assess thyroid function and possible autoimmune activity.

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.

Understand your thyroid hormone transport with our Thyroxine-Binding Globulin Blood Test. This protein carries thyroid hormones through your bloodstream, and measuring its levels can help explain abnormal thyroid function test results and guide an accurate thyroid health assessment.
