Our thyroid antibody test will determine how your thyroid is performing by looking at thyroid stimulating hormone (TSH), free thyroxine (T4), free triiodothyronine (T3), TGAB and TPEX. The presence of TGAB or TPEX antibodies can indicate thyroid damage which can include autoimmune disorders.
Hypothyroidism (Underactive Thyroid) occurs when the thyroid gland is not producing a sufficient level of thyroxine (T4) and triiodothyronine (T3).
- Weight gain
- Fatigue or feeling tired all the time
- Slow pulse or heart rate
- Hair loss or thinning
- Poor tolerance of the cold
- Dry, coarse or thickened skin
- Hand tingling or pain (carpal tunnel syndrome)
- Irregular period or low sex drive
- Muscle cramps
- Impaired memory
Hyperthyroidism (Overactive Thyroid) occurs when the thyroid gland produces an excessive level of thyroxine (T4) and triiodothyronine (T3).
- 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 bowel movements or diarrhea
- Irregular period
- Low sex drive
- Enlarged thyroid gland (goiter)
- Eye condition related to hyperthyroidism
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.
Thyroxine (T4) is one of two major hormones produced by the thyroid gland. It is required to regulate metabolism. T4 is found in two different forms, bound to proteins, or free (unbound) in the bloodstream. Protein bound T4 cannot enter the cells of the body for use in metabolism. Free thyroxine (FT4) is biologically active and readily available for use by the body.
