The prolactin blood test is a straightforward but essential diagnostic tool that measures the level of prolactin, a hormone produced by the pituitary gland. Prolactin plays a critical role in the body's reproductive system, particularly in regulating milk production in women after childbirth. For both men and women, abnormal prolactin levels can signal various health issues, ranging from hormonal imbalances to more serious conditions like pituitary tumors. This article will explore the significance of the prolactin blood test, when it might be necessary, and how services like Youth Revisited are making it easier for people in the UK to access this test online.

What is Prolactin?

Prolactin is a hormone primarily involved in the production of milk (lactation) in women following childbirth. It is produced by the pituitary gland, which sits at the base of the brain. Although prolactin is more commonly associated with women, it is also present in men and non-pregnant women, where its exact role is less understood but still important.

In addition to its role in lactation, prolactin affects reproductive health, sexual behavior, and other bodily functions. Both abnormally high levels (hyperprolactinemia) and abnormally low levels (hypoprolactinemia) of prolactin can lead to health problems, such as menstrual disturbances, fertility issues, or even abnormal breast development in men.

Why is the Prolactin Blood Test Important?

The prolactin blood test is designed to measure how much prolactin is circulating in the bloodstream. This is important because abnormal levels can point to various conditions that might need attention. For example:

• High prolactin levels (Hyperprolactinemia): Elevated prolactin can lead to symptoms like irregular or absent menstrual cycles, infertility, and unwanted milk production (galactorrhea) in women who are not breastfeeding. In men, high prolactin can cause reduced libido, erectile dysfunction, and gynecomastia (enlarged breast tissue).

• Low prolactin levels (Hypoprolactinemia): Although less common, low levels of prolactin can result from damage to the pituitary gland or hypothalamus. This can sometimes affect a woman’s ability to produce milk after childbirth.

Conditions Associated with Abnormal Prolactin Levels:

• Pituitary tumors (Prolactinomas): Benign tumors of the pituitary gland, called prolactinomas, are a common cause of hyperprolactinemia. These tumors overproduce prolactin, leading to high levels in the bloodstream.

• Hypothyroidism: An underactive thyroid (hypothyroidism) can also result in elevated prolactin levels.

• Medications: Certain drugs, such as antipsychotics, antidepressants, and high blood pressure medications, can interfere with prolactin regulation and increase levels.

The prolactin test is a key diagnostic tool in helping doctors identify these conditions, understand their underlying causes, and begin appropriate treatments.

How is the Prolactin Blood Test Performed?

The prolactin blood test is a simple and quick procedure. A healthcare professional typically draws a sample of blood from a vein in your arm. The sample is then sent to a laboratory for analysis. The results show the concentration of prolactin in the blood, usually measured in nanograms per milliliter (ng/mL).

Normal prolactin levels:

• Women (not pregnant): 4-23 ng/mL

• Pregnant women: 34-386 ng/mL (levels rise significantly during pregnancy)

• Men: 3-15 ng/mL

It is important to note that prolactin levels can fluctuate throughout the day, so the timing of the test (typically in the morning) is crucial for accuracy.

When Should You Get a Prolactin Test?

A prolactin blood test may be recommended if you experience symptoms such as:

• Irregular or absent menstrual cycles in women

• Unexplained infertility

• Galactorrhea (milk production without breastfeeding)

• Erectile dysfunction or reduced libido in men

• Headaches or vision problems (which can be related to pituitary tumors)

It is also important for individuals with thyroid problems or those taking certain medications that can impact prolactin levels to have their levels checked periodically.
