The Prolactin Test quantifies prolactin hormone secreted by the pituitary gland, regulating lactation and reproductive functions. Elevated prolactin (hyperprolactinemia) can cause menstrual irregularities, infertility, sexual dysfunction, and galactorrhea (milk production outside pregnancy). Causes include pituitary tumors, hypothyroidism, medications, or stress. The test aids diagnosis, treatment monitoring, and evaluation of unexplained reproductive symptoms. Blood is typically drawn fasting in the morning for accuracy. Redcliffe Labs offers expert home collection and accurate reporting to support endocrine and reproductive health care
