Prolactin Test

The Prolactin Test at Pamel Laboratories measures the level of prolactin, a hormone produced by the pituitary gland that plays a vital role in breast development and milk production in women. In both men and women, abnormal prolactin levels may indicate a hormonal imbalance, pituitary tumor, or fertility issue.

This test is especially important for individuals experiencing irregular menstrual cycles, infertility, unexplained nipple discharge, or erectile dysfunction.

What the Test Measures:

• The concentration of prolactin in the blood

• Evaluates pituitary gland activity and reproductive function

Purpose of the Test:

• In women:

  • Investigate missed or irregular periods

  • Diagnose causes of infertility

  • Assess nipple discharge (galactorrhea)

  • Evaluate pituitary disorders (e.g., prolactinoma)

• In men:

  • Investigate low libido or erectile dysfunction

  • Assess testosterone suppression and infertility

• In both sexes:

  • Diagnose pituitary tumors or assess pituitary gland function

Sample Type: Blood sample (serum)
Fasting Required: Preferred (early morning sample recommended)
Turnaround Time: 1–2 working days

Interpretation Guide:

• High prolactin (hyperprolactinemia): May indicate a pituitary tumor, hypothyroidism, stress, or certain medications

• Low prolactin: Rare but may suggest pituitary dysfunction

Further testing (e.g., MRI of the brain, thyroid function tests) may be recommended based on results
