Is your thyroid self-destructing?

Our Advanced Thyroid Check provides more in-depth screening of thyroid function and looks for evidence of autoimmune disease with a thyroid antibodies test. The hormones produced by the thyroid regulate metabolism - the rate at which the body uses energy. The body has a feedback system that turns thyroid hormone production on and off and maintains a stable amount of thyroid hormones in the bloodstream. When thyroid antibodies interfere with this process, it can lead to chronic conditions such as Hashimoto thyroiditis or Graves' disease.

A thyroid antibodies test reveals situations where the immune system mistakenly attacks the thyroid and can lead to chronic inflammation of the thyroid (thyroiditis), tissue damage, and disruption of thyroid function. An underactive or hypothyroid can cause symptoms such as weight gain, fatigue, dry skin, hair loss, intolerance to cold, and constipation. Conversely an overactive or hyperthyroid can cause sweating, rapid heart rate, anxiety, tremors, fatigue, difficulty sleeping and sudden weight loss.

What we test

Thyroid Function

Your thyroid gland produces hormones that regulate growth and energy expenditure. Thyroid disorders are quite common, and many people don’t have any symptoms at all. This thyroid test screens for the thyroid hormones that play a key role in regulating the body’s metabolism.

This thyroid test measures:

Communicates with the thyroid gland to produce T3 and T4 which regulate metabolic functions. High TSH thyroid test levels indicates an underactive thyroid, and low levels an overactive thyroid.

Measures the thyroxine that is freely circulating and able to regulate metabolism. High FT4 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.

Measures the triiodothyronine that is freely circulating. High FT3 thyroid test levels indicate an overactive thyroid, and low levels an underactive thyroid.

Thyroid Antibodies

In addition to screening for the thyroid hormones that play a key role in regulating metabolism, this advanced thyroid function test detects and measures the quantity of specific thyroid autoantibodies to determine whether autoimmune disease may be impacting thyroid function.

This thyroid antibodies test includes:

Thyroid peroxidase antibodies work against thyroid peroxidase, an enzyme that plays a part in the T4-to-T3 conversion and synthesis process. TPO antibodies can be evidence of tissue destruction, such as Hashimoto's disease.
