What is TSH blood work?

New Delhi : TSH blood work is a simple blood test that measures the amount of thyroid-stimulating hormone (TSH) in your blood. The hormone is secreted by the pituitary gland in your brain. It plays a vital role in regulating the function of your thyroid gland. 

The thyroid is a butterfly-shaped gland in the middle of the neck. Your thyroid produces hormones that regulate how your body uses energy. Thyroid hormones affect almost every organ in your body, including your heart. They help control your weight, body temperature, muscle strength, and mood. When you don’t have enough thyroid hormone in your blood, your body slows down. Having too much often speeds up the body's processes. 

A TSH test tells you if your thyroid is making the right amount of the hormone. If you are wondering about the thyroid test price, please read below.
