Pituitary function testing

Scope

Comprehensive pituitary function testing assesses each anterior pituitary hormone axis (thyroid, adrenal, gonadal, growth hormone, prolactin) individually, since pituitary disease can affect one, several, or all axes to differing degrees - a "panel" approach testing all axes is generally needed rather than assuming uniform involvement
Performed whenever pituitary pathology (mass lesion, or clinical suspicion of hormone excess/deficiency) is identified or suspected, given the need to characterise the full functional impact across all pituitary-dependent hormone axes
