Prolactin Test

Can stress affect this test?

Yes, physical or emotional stress, and even the stress of the blood draw itself, can temporarily raise prolactin, so a calm, rested state and sometimes a repeat test are recommended for accurate interpretation.

What is a prolactinoma?

It's a usually benign, hormone-secreting tumor of the pituitary gland that causes prolactin overproduction — most cases are effectively managed with medication rather than surgery.

Can men have prolactin problems too?

Yes, elevated prolactin in men can cause low libido, erectile dysfunction, and reduced testosterone, so this test isn't limited to women's health concerns.
