Pituitary Assessment Strategy

Abstract

Accurate assessment of anterior pituitary function requires a sound knowledge of its normal physiology together with careful integration of clinical and biochemical information. The optimum methods of testing anterior and posterior pituitary function and the interpretation of the results are subjects of continuing debate. The syndromes associated with and consequences of hypo- and hyperpituitarism; and the diagnosis and treatment of diabetes insipidus are all discussed elsewhere in this book. The intention of this chapter is to describe the physiological basis and evidence in favour of the various available tests of anterior pituitary function, while at the same time acknowledging their limitations and appreciating the importance of the clinical context of testing.
