Laboratory Evaluation

Abstract

A variety of laboratory assessment and imaging studies can be ordered to guide the management of patients with suspected endocrine abnormality. These are selected based on the clinical presentation. In this chapter, we thereby classify them into hormonal evaluation (e.g. β‎-hCG, oestradiol, progesterone, LH and FSH, androgens (testosterone, DHEAS), 17 α‎-hydroxyprogesterone (17 OHP), prolactin, growth hormone, anti-Mullerian hormone (AMH), thyroid hormone, cortisol), imaging studies (e.g. head, ovarian, adrenal, bone density, and thyroid), and other assessments (e.g. karyotype, fragile X testing, autoimmune testing, insulin resistance testing) that are helpful in diagnosing these conditions and evaluating for other associated abnormalities. A full references list and illustrative tables provide further reading and information.
