Our home thyroid antibody test will determine how your thyroid is performing by looking at thyroid stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), TGAB, and TPEX. The presence of TGAB or TPEX antibodies can indicate thyroid damage which can include autoimmune disorders.

About this test
Hypothyroidism Symptoms
Hypothyroidism (Underactive Thyroid) occurs when the thyroid gland is not producing a sufficient level of thyroxine (T4) and triiodothyronine (T3).
Symptoms can include:
Weight gain
Fatigue or feeling tired all the time
Slow pulse or heart rate
Hair loss or thinning
Poor tolerance of the cold
Depression
Dry, coarse or thickened skin
Constipation
Hand tingling or pain (carpal tunnel syndrome)
Irregular period or low sex drive
Muscle cramps
Impaired memory
Hyperthyroidism Symptoms
Hyperthyroidism (Overactive Thyroid) occurs when the thyroid gland produces an excessive level of thyroxine (T4) and triiodothyronine (T3).
Symptoms can include:
Weight loss
Fatigue or feeling tired all the time
Increase or rapid heart rate
Tremors (usually in the hands)
Heat intolerance or excessive sweating
Difficulty sleeping
Excessive sweating or fever
Frequent colon movements or diarrhea
Anxiety
Irregular period
Low sex drive
Enlarged thyroid gland (goiter)
Eye condition related to hyperthyroidism
When to test
You should consider getting tested if you:
Have symptoms of an overactive thyroid
Have symptoms of an underactive thyroid
Have a family history of thyroid conditions
Have an autoimmune condition such as celiac disease or type 1 diabetes
The sample must be collected in the morning, on Monday-Friday, and returned on the same day.
What's measured
Thyroid Stimulating Hormone (TSH)
Thyroid stimulating hormone (TSH), also known as thyrotropin, is a hormone produced by the pituitary gland of the brain. The release of TSH stimulates the thyroid gland to produce thyroxine (T4) and triiodothyronine (T3). These hormones regulate the body’s metabolism.
Free Thyroxine (FT4)
Free thyroxine (FT4) is the biologically active form of thyroxine, a hormone produced in the thyroid gland to regulate your metabolism. FT4 is not bound to proteins and is available for use by the tissues of the body. Raised FT4 levels can indicate an overactive thyroid (hyperthyroidism), low FT4 levels can indicate an under active thyroid (hypothyroidism).
Free Triiodothyronine (FT3)
Free triiodothyronine (FT3) is one of two major hormones produced by the thyroid gland. FT3 is more biologically active than thyroxine (T4) and is required to regulate metabolism. FT3 is produced directly by the thyroid gland, and through the conversion of T4 to T3 in other cells of the body.
Thyroglobulin Antibodies (TGAB)
TGAB is an antibody which can indicate thyroid damage caused by an autoimmune disorder.
Thyroid Peroxidase Antibodies (TPO/TPEX)
TPEX is an antibody which can indicate thyroid damage caused by an autoimmune disorder.
