Thyroid Health

At-home iodine loading challenge test assessing whole-body iodine stores through 24-hour urine collection after a measured iodine dose. Higher retention indicates depleted stores. More informative than spot urine testing alone.

At-home spot urine test measuring urinary iodine concentration from a single morning sample. Screens whether recent dietary iodine intake appears adequate for thyroid function. Results compared to WHO reference ranges.

Measures iodine concentration in a single urine sample collected at a pathology centre. Screens recent dietary iodine intake and flags potential deficiency affecting thyroid function. Results compared to WHO reference ranges.

NutriSTAT looks at how your body is actually working, not just whether your numbers sit inside a reference range. One at-home collection kit covers metabolic function, thyroid markers, cardiovascular risk factors, hormones, essential minerals, toxic metals, fatty acids, amino acids, and organic acids.

The Reverse T3 (rT3) Blood Test measures an inactive form of thyroid hormone produced when the body diverts T4 away from the active T3 pathway. This can occur during physical stress, illness, or calorie restriction, and may contribute to low thyroid symptoms even when standard thyroid tests appear normal.

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.

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 TPO and thyroglobulin antibodies to assess whether the immune system is attacking the thyroid. Elevated antibodies are associated with autoimmune thyroid conditions including Hashimoto's thyroiditis and Graves' disease.

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.
