Endocrine System and Syndromes
Tests
The goals of endocrine testing are to identify the hormone(s) that are being over- or under-produced, to determine which gland(s) are involved, and to determine the cause of the hormone imbalance. This may involve measuring hormone levels and their metabolites in the blood and/or urine. Stimulation or suppression testing may be utilized to evaluate hormone production and/or gland interaction with other glands and hormones. If a tumor is suspected, then imaging scans may be used to help locate the tumor. If symptoms are suspected to be due to an inherited condition, then genetic testing may be recommended. Patients often see an endocrinologist (an endocrine gland specialist) to help them determine the appropriate testing and treatment. Related testing on this site includes:
