When to Get Tested

Best drawn in the morning, a few hours after waking, since prolactin is higher during sleep and can rise with stress, exercise, or nipple stimulation. No fasting is required.

Understanding Your Results

Results post to your secure online account usually in 1–2 business days, with your value and the reference range. Mild elevations can be caused by stress or a recent meal and often resolve on a repeat test; persistently high results should be evaluated by a clinician.

Frequently Asked Questions

Do I need to fast?
No fasting is required, but test in the morning a few hours after waking and try to be relaxed, since stress and activity can temporarily raise prolactin.
Why might my prolactin be mildly high?
Stress, exercise, a recent meal, or nipple stimulation can raise it briefly. A repeat test under calm conditions often clarifies the result.
