The pituitary is a pea-sized gland that is attached to an area at the base of the brain called the hypothalamus. The pituitary gland is part of the endocrine system; a system of glands that produce and regulate hormones. The hypothalamus communicates with the rest of the brain and nervous system. It senses the body’s need for more or less of a particular hormone and controls the amount of hormone released from the pituitary gland.
The goals of pituitary disorder testing are to detect excess or deficient hormone production, determine the cause, and evaluate the severity of the condition. Testing frequently includes measurements of both the hormones that the pituitary produces (e.g. TSH), and the hormones of other endocrine glands that the pituitary is responsible for stimulating (e.g. the thyroid hormone thyroxine).
