Hormones

Measures total testosterone in blood, the primary androgen hormone in both men and women. Testosterone influences energy, muscle mass, bone density, mood and sexual function.

Measures total testosterone, calculated free testosterone, and SHBG in a single blood draw. Used to investigate low testosterone in men and androgen excess in women. Morning collection required, as testosterone peaks in the early hours.

Measures 100 health biomarkers in a single blood draw, covering hormones, vitamins and minerals, organ function, inflammation, immune health, iron and metabolic markers. Available in separate male and female panels.

A targeted blood test for people who train regularly, covering the biomarkers most relevant to fitness: hormones, iron status, inflammation and key vitamins and minerals.

Measures thyroglobulin, a protein produced exclusively by thyroid tissue. Used primarily to monitor for residual or recurrent thyroid cancer after thyroidectomy or radioiodine treatment, where levels are expected to be very low or undetectable.

Measures TSH, Free T4 and Free T3, the three key hormones used to assess how well the thyroid gland is working. Results can help identify an underactive or overactive thyroid, or flag that hormonal compensation is occurring elsewhere in the system.

Measures thyroid receptor antibodies (TRAb), which can stimulate the thyroid to overproduce hormones. Used to investigate Graves' disease, monitor treatment response, and assess thyroid-related risks during pregnancy.

Measures thyroxine-binding globulin (TBG), the main protein that transports thyroid hormones in the bloodstream. Changes in TBG levels can make standard thyroid results appear misleading, so this test helps clarify whether abnormal hormone readings reflect true thyroid dysfunction or altered transport.
