TSH Assay for Thyroid Assessment Access TSH (3rd IS)

Description

Thyroid assessment for today and the future Measuring thyroid stimulating hormone TSH is useful in assessing thyroid function and monitoring patients undergoing thyroid replacement therapy. The Access TSH 3rd IS assay can help you provide physicians and their patients with reliable, accurate results for each test, every time. TSH is part of the hypothalamic-pituitary-thyroid axis that regulates the bodys metabolism. The hypothalamus secretes a thyrotropin-releasing hormone TRH , stimulating the pituitary gland to secrete TSH. TSH causes the release of thyroid hormones, T3 triiodothyronine and T4 thyroxine , which control metabolic functions within the cells. When excessive amounts of T3 or T4 circulate, production of TRH stops, resulting in the process being controlled by a negative feedback loop.
