The Prolactin test measures the concentration of prolactin, a protein hormone produced and secreted by the lactotroph cells in the anterior pituitary gland. While its primary and most well-known biological role is to stimulate and sustain breast milk production (lactation) after childbirth, prolactin also plays a vital role in regulating reproductive health, immune function, and emotional balance in both men and women. Measuring prolactin levels is a vital clinical tool used to identify hypothalamic-pituitary axis disorders and pinpoint the root cause of reproductive dysfunction. 🩺🌸

When is this test performed and for which diseases? 🤔

• To Investigate Pituitary Tumors: This test is performed urgently when a patient experiences chronic headaches or unexplained vision problems to diagnose a Prolactinoma (a benign, prolactin-secreting tumor of the pituitary gland). 🧠🚨

• To Evaluate Irregular Menstruation and Infertility: It is ordered for women experiencing unexplained difficulties in conceiving or altered menstrual cycles to diagnose Hyperprolactinemia or Amenorrhea (complete absence of periods). 👶📊

• To Check for Abnormal Breast Milk Production: This examination is performed for both non-pregnant women and men who experience inappropriate nipple discharge to evaluate Galactorrhea. 🛑

• To Diagnose Male Reproductive Dysfunction: It is performed for men experiencing decreased sex drive, erectile difficulties, or enlarged breast tissue to identify Male Hypogonadism caused by elevated prolactin suppressing testosterone production. 🧑‍⚕️

Test Specifications: 📋

• Sample Type: Blood (Serum) 🩸

• Preparation: No fasting is required. However, because prolactin levels naturally peak during sleep and fluctuate with physical stress, it is highly recommended to have your blood drawn 3 to 4 hours after waking up in the morning. Sit quietly and rest for 15 minutes before the draw to avoid stress-induced spikes. ⏳☀️

• Reporting: High-precision quantitative hormone results are typically delivered within 24 hours. ⏱️
