Order Prolactin Levels Blood TestProlactin is a hormone produced by the pituitary gland, a small structure at the base of the brain. Although it is best known for its role in breast development and milk production, prolactin participates in a broader set of regulatory functions in both women and men. A prolactin levels blood test measures how much of this hormone is circulating in the bloodstream at the time of collection.
About Prolactin Levels Blood Test in Tysons
What the prolactin levels blood test measures
The test quantifies prolactin, a peptide hormone secreted by specialized cells in the anterior pituitary. Its release is normally kept in check by dopamine, a neurotransmitter that travels from the hypothalamus to the pituitary and suppresses prolactin production. When dopamine signaling falls or when prolactin-secreting cells multiply, blood prolactin concentrations can rise.
Because prolactin is released in pulses and tends to be higher during sleep, after exercise, and in response to stress or nipple stimulation, a single elevated result does not automatically indicate disease. Clinicians often interpret the number alongside symptoms, the time of day the sample was drawn, and sometimes a repeat measurement. Medications, pregnancy, breastfeeding, and thyroid function can all influence the result.
Results are typically reported in nanograms per milliliter (ng/mL), though some laboratories use micrograms per liter (mcg/L), which is numerically equivalent. Reference ranges vary by laboratory and by sex. A prolactin level above the upper limit of the reference range may prompt further evaluation, such as additional hormone testing or imaging of the pituitary region, depending on the clinical picture.
