GH Test for Pituitary Tumors - Immunohistochemistry: Growth Hormone (GH)

Growth hormone (GH) immunohistochemistry aims to detect the presence and distribution of growth hormone within pituitary cells in pituitary tissue samples. It is primarily used to confirm the diagnosis of a GH-secreting pituitary tumor (growth hormone-secreting somatotroph adenoma), the leading cause of acromegaly and gigantism.
