What is a bad prolactin level?

Hyperprolactinemia is usually defined as fasting levels of above 20 ng/ml in men and above 25 ng/ml in women[9] at least 2 hours after waking up. Unless the prolactin levels are markedly elevated, the investigation should be repeated before labeling the patient as hyperprolactinemic.

What level of prolactin indicates a tumor?

A prolactin level above normal obtained without excessive venipuncture-induced stress confirms the diagnosis. Prolactin levels associated with stress or dopamine antagonists are usually below 100 μg/dl. A prolactin level greater than 250 μg/dl usually indicates the presence of a prolactinoma.

What causes high levels of prolactin?

Its hormones help regulate important functions such as growth, metabolism, blood pressure and reproduction.

What level of prolactin is considered high?

This is called galactorrhea. Patients with pituitary tumours have very high levels – typically more than 100 ng/ml. A high prolactin level could sometimes just be because of stress – and even the stress of doing a venepuncture for drawing a blood sample can cause an artificial elevation in your prolactin levels.

What are the dangers of high prolactin levels?
