Prolactin Test Guide: Purpose, Procedure, Results and Price

The human body has different types of hormones that help to regulate mood and metabolism. One such is prolactin, which is essential for both men and women. However, when there is an imbalance in the hormone, health issues arise. To overcome the issue and get the exact picture, doctors prescribe a prolactin test.

The test measures prolactin levels in your blood and is commonly known as the serum prolactin test. The pituitary gland, a little gland near the base of the brain, produces the hormone prolactin. Prolactin levels are typically low in women who are not nursing or pregnant. Prolactin affects reproductive function and is found in trace levels in men.

What is Prolactin Test?

A prolactin test is conducted to check the overall amount of the prolactin hormone in your blood. Prolactin is primarily associated with pregnancy and lactation, although it also affects the immune response, metabolism, and reproductive health. The pituitary gland, a small gland near the base of the brain, produces prolactin. Its primary function is to promote breast milk production after childbirth, but it also supports reproductive health and regulates other hormones.

Prolactin levels often rise during pregnancy and lactation. Prolactin levels that are high or low outside these settings may indicate underlying health issues that require further assessment.

Why is the Prolactin Test Done?

There could be several reasons why doctors recommend this test. It depends on the patient's age, symptoms, and other factors. Some of the reasons are-

• To determine the reason behind irregular or nonexistent menstruation.

• Examine male or female infertility

• Analyze the production of breast milk that cannot be explained.

• Identify conditions affecting the pituitary gland, such as prolactinoma

• Examine men with low testosterone levels.

• Examine erectile dysfunction or decreased libido.

There are different symptoms in men and women.

Symptoms in men:

• Erectile dysfunction

• Reduced sexual desire

• Infertility

• Low testosterone levels

• Enlarged breast tissue

Symptoms in women

• Irregular menstrual cycles

• Missed periods

• Difficulty conceiving

• Breast milk discharge without pregnancy or breastfeeding

• Breast tenderness

Preparation for the Prolactin Test

No special preparation is required to undergo the test. However, the doctor may advise you to follow:

• Avoid any kind of intense exercise.

• For at least a day, refrain from stimulating your breasts or nipples.

• Tell your doctor about all the supplements and medications you take.

• Since prolactin levels naturally change during the day, take the test in the morning.

• Because stress may temporarily raise prolactin levels, take a 20–30-minute break before drawing blood.

Besides, in some cases, the doctor may ask you to fast for 3- 4 hours before the test. Also, it is best to provide a complete medical history to help you prepare well. The test doesn’t lead to any harm or pain. The lab expert will conduct the test smoothly.

Understanding the Prolactin Test Report

Once the test is conducted, the doctor will examine the report, which contains the complete measured level. In addition to varying with pregnancy and breastfeeding, normal prolactin levels also differ between men and women.

• High Prolactin Level: Elevated prolactin levels may be associated with thyroid issues, pituitary gland growths, certain medications, or other medical conditions.

• Low Prolactin Levels: Although less common, low-normal levels might nevertheless be helpful in cases of pituitary problems or lactation issues.

Prolactin Test Price

One important consideration is to check the prolactin test price. Depending on the city, the diagnostic facility, and prescription, the cost of a prolactin test may differ. Besides, you need to check whether the lab offers home sample collection and which packages it offers.

What if the Prolactin Level Result is Abnormal?

In case the prolactin test result is abnormal, the doctor may suggest further tests. This includes:

• An MRI of the pituitary gland

• Tests for thyroid function

• Tests for kidney function

• Tests for liver function

• Test for pregnancy (for women)

Additional tests for reproductive hormones

Depending on the underlying cause, treatment options may include hormone therapy, medication, or pituitary problem treatment.

Why should you get Early Prolactin Test?

Doctors recommend that patients with symptoms undergo an early test, as it benefits from:

• Early detection of hormonal imbalances

• Prompt management of disorders associated with infertility

• Improved treatment of diseases of the pituitary gland

• Tracking the efficacy of treatment

Conclusion

The Prolactin test is a simple and useful diagnostic method for assessing hormonal balance and reproductive health in both men and women. Infertility, irregular menstrual cycles, pituitary gland issues, and unexplained breast milk output are among the conditions it aids in diagnosing. 

The test provides crucial information to guide precise diagnosis and therapy from a fast blood sample with minimal preparation.
