How to Prepare for Prolactin Test

Avoid stress, vigorous exercise, and nipple stimulation for at least an hour before the test, as all of these can temporarily raise prolactin levels.
Morning testing is often preferred, ideally a few hours after waking, since prolactin levels can be affected by sleep.
Mention all medications you're taking, since several common drugs are known to raise prolactin.
