Prolactin Levels Test Reports

Prolactin test results are measured in nanograms per milliliter (ng/mL) and interpreted based on age, sex, and physiological conditions such as pregnancy. Normal levels are typically below 20 ng/mL for men, below 25 ng/mL for non-pregnant women, and between 80–400 ng/mL for pregnant women (UCSF Health, 2022). Deviations may indicate hormonal imbalances or underlying medical conditions.

Prolactin levels above 25 ng/mL in non-pregnant women or 20 ng/mL in men may be concerning and could indicate hyperprolactinemia. Levels exceeding 200 ng/mL often suggest a prolactinoma, a benign pituitary tumor that requires further evaluation.

A prolactin test is not part of a complete blood count (CBC). It is a specific hormone test used to measure prolactin levels in the blood and assess pituitary function. It is often ordered separately when hormonal imbalances or related symptoms are suspected.
