Hormone Health Markers

Blood markers measuring hormone levels including thyroid function, sex hormones, adrenal hormones, and reproductive health indicators.

17 biomarkers

About Hormone Health Markers

Hormone health markers encompass a wide range of biomarkers that assess the function of your endocrine system. This includes thyroid hormones (TSH, FT3, FT4), sex hormones (testosterone, estrogen, progesterone), adrenal hormones (cortisol, DHEA-S), and reproductive hormones (FSH, LH, AMH).

Hormonal balance is crucial for energy, mood, metabolism, fertility, and overall quality of life. Imbalances can manifest as fatigue, weight changes, mood disturbances, reduced libido, menstrual irregularities, and many other symptoms. Regular hormone testing helps identify issues early and guides appropriate treatment.

All Hormone Health Markers

Anti-Mullerian Hormone (AMH)

pmol/L

A hormone produced by the ovaries that indicates egg quantity.

Anti-TG (Thyroglobulin Antibodies)

IU/mL

Antibodies targeting thyroglobulin, a protein essential for thyroid hormone production.

Learn more

Cortisol

nmol/L

The primary stress hormone produced by the adrenal glands.

D.H.E.A. Sulphate (DHEAS)

μmol/L

An adrenal hormone that serves as a precursor to sex hormones.

Learn more

Estradiol (Oestradiol, E2)

pmol/L

Oestradiol (E2) is the most potent of the three forms of oestrogen. In women it is produced primarily by the ovaries and varies dramatically across the menstrual cycle. In men it is produced by aromatisation of testosterone in fat, brain, bone and other tissues. Australian pathology labs report E2 in pmol/L; older US-style ng/dL or pg/mL conversions are sometimes seen on imported reports.

Ferritin

μg/L

Ferritin is the body's main iron-storage protein. The amount of ferritin circulating in blood reflects how much iron is held in tissue stores (mostly liver, spleen and bone marrow). Because ferritin is also an acute-phase reactant, levels can rise temporarily during infection or inflammation, which can mask underlying iron deficiency.

FSH (Follicle Stimulating Hormone)

IU/L

A pituitary hormone that stimulates egg and sperm production.

Learn more

FT3 (Free Triiodothyronine)

pmol/L

The unbound, biologically active form of T3, the most potent thyroid hormone.

Learn more

FT4 (Free Thyroxine)

pmol/L

The unbound, biologically active form of T4, the main thyroid hormone.

Learn more

LH (Luteinising Hormone)

IU/L

A pituitary hormone that triggers ovulation and stimulates testosterone production.

Learn more

Progesterone

nmol/L

A hormone produced mainly by the ovaries that prepares the uterus for pregnancy.

Learn more

Prolactin

mIU/L

A hormone best known for stimulating milk production.

Learn more

PSA (Prostate-Specific Antigen)

ng/mL

PSA is a protein produced by both healthy and cancerous prostate cells, measured in nanograms per millilitre (ng/mL). It is a screening signal — not a cancer diagnosis — used to decide whether further investigation (free PSA ratio, multiparametric MRI, biopsy) is warranted. Australian guidelines (RACGP, Cancer Council Australia) use age-adjusted thresholds rather than a single cut-off because PSA naturally rises with age as the prostate enlarges.

SHBG (Sex Hormone Binding Globulin)

nmol/L

SHBG (Sex Hormone Binding Globulin) is a glycoprotein produced by the liver that binds tightly to testosterone, dihydrotestosterone (DHT) and oestradiol. The portion of testosterone bound to SHBG is biologically inactive, so SHBG levels directly determine how much "free" (bioavailable) testosterone reaches tissues. Insulin and androgens lower SHBG; oestrogen, thyroid hormone and ageing raise it.

Learn more

T4 (Thyroxine)

pmol/L

The main hormone produced by the thyroid gland.

Learn more

Testosterone

nmol/L

Testosterone is the primary androgen (male sex hormone), produced mostly in the testes in men and in much smaller amounts by the ovaries and adrenal glands in women. Australian pathology labs report testosterone in nmol/L. Most circulating testosterone is bound to SHBG and albumin; only the small "free" fraction is biologically active. Levels follow a strong circadian pattern, peaking in the early morning, which is why diagnostic samples should be taken before 10 am.

TSH (Thyroid Stimulating Hormone)

mIU/L

TSH (Thyroid Stimulating Hormone) is produced by the pituitary gland and tells the thyroid how much thyroid hormone (T4 and T3) to make. It works on a feedback loop: when circulating thyroid hormone is low, TSH rises to stimulate more production; when thyroid hormone is high, TSH falls. Because the feedback loop is so sensitive, TSH typically changes before T4/T3 do — making it the single most useful screening test for thyroid dysfunction. Australian pathology labs report TSH in mIU/L (also written μIU/mL or mU/L — they are equivalent).

Frequently Asked Questions

When is the best time to test hormone levels?
Testosterone should be tested in the morning (7-10 AM) when levels peak. Female hormones vary by cycle day - FSH and estradiol on days 2-5, progesterone around day 21. Thyroid markers can be tested any time.
What symptoms indicate hormone imbalance?
Common symptoms include fatigue, unexplained weight changes, mood swings, low libido, hair loss, sleep disturbances, irregular menstrual cycles, and difficulty building muscle or losing fat.
How do thyroid hormones affect the body?
Thyroid hormones regulate metabolism, energy production, body temperature, heart rate, and mood. Too little (hypothyroidism) causes fatigue and weight gain; too much (hyperthyroidism) causes anxiety and weight loss.
Should I test all thyroid markers or just TSH?
While TSH is the standard screening test, a full panel including Free T3, Free T4, and thyroid antibodies provides a more complete picture, especially if you have symptoms despite normal TSH.
