PROLACTIN (PRL)

The prolactin (PRL) test measures the level of prolactin, a hormone produced by the pituitary gland, in the blood. Prolactin is essential for milk production in breastfeeding women but can also affect reproductive health in both men and women. This test is used to diagnose and monitor conditions affecting prolactin levels, such as hyperprolactinemia, prolactinomas, and pituitary disorders. Elevated prolactin levels can indicate conditions such as pituitary tumors or hypothyroidism, while low levels suggest hypopituitarism. The prolactin test provides valuable information for managing reproductive health, diagnosing endocrine disorders, and guiding treatment decisions.
