Prolactin

Overview:
Prolactin is a hormone produced by the pituitary gland that plays an essential role in lactation (milk production) in women. The Prolactin test measures the level of prolactin in the blood and is commonly used to investigate causes of abnormal lactation or fertility issues in both men and women.

What it detects:
This test detects the level of prolactin and is used to:

Investigate abnormal lactation (galactorrhea), which can occur even when a woman is not breastfeeding.

Evaluate fertility issues, including ovulation problems in women and low sperm count or erectile dysfunction in men.

Detect pituitary tumors (prolactinomas) that may cause excessively high levels of prolactin.

Monitor medication effects, as certain drugs can increase prolactin levels.

Who should get it:
This test is recommended for individuals who:

Experience irregular periods, infertility, or unexplained lactation.

Have signs or symptoms of a pituitary disorder such as headaches, vision problems, or galactorrhea.

Are undergoing fertility treatment or have concerns about reproductive health.

Have sexual dysfunction or other issues related to hormonal imbalances.

Sample required:
A blood sample is required for this test.

Fasting requirements:
Fasting is not required for this test. However, prolactin levels can fluctuate throughout the day, so it's best to have the test performed in the morning, and ideally, avoid any stress or breast stimulation before the test.

Processing time:
Results are typically available within 24-48 hours.
