What can be the range of serum prolactin in pitutary adenoma .. kindly tell ?

Should help: Prolactin levels vary based on what the pituitary adenoma is primarily producing. Serum prolactin level >200 mcg/l in a patient with a macroadenoma greater than 10 mm in size is diagnostic of a prolactinoma. Levels below that range in a macroadenoma suggest hyperprolactinemia secondary to hypothalamic compression from another source.
