Thyroid Stimulating Hormone (TSH)

Released by the pituitary gland, TSH tells your thyroid to produce the hormones T3 and T4, which regulate how your body uses energy. It's usually the first marker checked to spot an underactive or overactive thyroid.

Free Thyroxine (FT4)

FT4 is the active form of thyroxine, a thyroid hormone that regulates metabolism, energy production, and reproductive function. Balanced FT4 levels are crucial for ovulation, menstrual cycle regularity, and overall hormonal balance

Free Triiodothyronine (FT3)

Free T3 is one of the primary hormones produced by the thyroid gland, playing a critical role in regulating metabolism, energy levels, and overall bodily functions. Free T3 represents the active form that is available for use by the body's cells.

Thyroid Peroxidase Antibodies (TPO-Ab)

TPO-Ab are antibodies that target the thyroid peroxidase enzyme, which is crucial for the production of thyroid hormones. Elevated levels of TPO-Ab can indicate an autoimmune disorder such as Hashimoto's thyroiditis or Graves' disease.
