Why Test Thyroid Function?

Thyroid dysfunction is one of the most under-addressed conditions in healthcare. There are thyroid receptors on every tissue in the body, demonstrating its necessity for all systems. Thyroid hormones impact energy production, cognitive function, mood, emotions, concentration, memory, and attention.

Hypothyroidism

Depression
Dry skin and brittle nails, or hair loss
Feeling tired or weak
Increased sensitivity to cold
Heavy or irregular menstrual cycles
Obesity

Joint Pain
Infertility
Constipation
Memory issues or unclear thinking
Hashimoto’s

Hyperthyroidism

Nervous or moody
Shaky hands, fast heartbeat
Sensation of being hot and sweaty
Increased bowel movements
Fine, thin hair, and hair loss

Weight loss without a change in eating patterns
Difficulty concentrating
Sleep problems or restlessness
Goiter or thyroid nodules
Weak, tired, fatigued

Standard measures of thyroid function may miss up to half the population
(According to the Journal of Endocrinology)

You must assess each step within thyroid function to ensure that the entire pathway is working effectively.

The Comprehensive Thyroid Panel w/Antibodies & Reverse T3 Test Measures the following from a single blood draw:

Thyroid Stimulating Hormone (TSH) – TSH causes the thyroid gland to make two hormones, T3 and T4, which help control the body’s metabolism. This test is done to find out whether the thyroid gland and brain-thyroid communication are working properly.
T4, Total – This test measures the total amount of T4 (Thyroxine) in blood.
T4, Free – Most of the T4 in the body binds to protein, the T4 that does not is called ‘free T4’ and circulates unbound in blood. This test measures the free T4 level individually also.
T3, Total – T3 (triiodothyronine) is the most important thyroid hormone for the body’s control of metabolism. This test measures the total amount of T3 in blood.
T3, Free – Most of the T3 in the body binds to protein, the T3 that does not is called ‘free T3’ and circulates unbound in blood. This test measures the free level individually also.
T3, Reverse – Reverse T3 is converted by the liver from the stored hormone T4, it is the body’s main way of getting rid of unneeded T4 every day. Sometimes the body can make too much reverse T3 from a number of causes including chronic emotional, physical, or biological stress, chronic sickness, after surgery, diabetes, ageing, or an acute injury. This test measures for levels of reverse T3.
Thyroid Peroxidase (TPO) Antibody – Thyroid peroxidase (TPO) is an important enzyme for producing thyroid hormone. TPO converts T4 to T3. High levels of TPO antibodies suggest the immune system is mistakenly attacking this enzyme and the thyroid gland, compromising thyroid activity.
Thyroglobulin (Tg) Antibody – Thyroglobulin (Tg) is a protein produced and used by the thyroid gland to make the hormones T3 and T4. High levels of antibodies to Tg suggest the immune system is mistakenly attacking the thyroid gland.
