Prolactin Hormone is produced by the pituitary gland. It indicates the normal physiological functioning of reproductive organs in healthy subjects and differentiates it from abnormal pathological states. This health check-up evaluates the prolactin hormone in the blood sample to diagnose fertility issues and complications during late pregnancy.


This test is usually done to assess and diagnose the hormone prolactin in the blood. In female after childbirth, the levels of prolactin is high since it increases the production of breast milk. HIGH PROLACTIN levels are due to medications like anti-depressants, drugs containing estrogen-like birth control pills, certain medications for hypertension and acid reflux pills, under-active thyroid and pituitary tumors, etc. Symptoms include infertility, milk discharge from nipples when not pregnant or nursing, irregular periods, loss of libido, vaginal dryness leading to painful intercourse, acne, and hirsutism (excessive body and facial hair growth). LOW PROLACTIN levels are due to postpartum pituitary necrosis (Sheehan’s syndrome), impairment of anterior pituitary secondary to pituitary (or extra pituitary) tumor, or treatment of tumor, head injury,  hypopituitarism, medications such as dopamine and levodopa or infections, etc. Symptoms include delay in puberty etc. This test is suggested in patients with symptoms of altered prolactin levels (pituitary function) suggesting hormonal imbalance etc. Other associated tests include radioimmunoassay, ELISA, spectrometric methods, and kit methods.
