A prolactin assay is a simple blood test that measures the amount of prolactin in your blood. Prolactin is a hormone made by the pituitary gland. This test helps doctors check for problems with hormone levels. Because hormone balance is important for many body functions, a prolactin assay can give helpful clues about your health. In this guide, you will learn what a prolactin assay is, why it is done, and what to expect during the test.
What is a Prolactin Assay?
A prolactin assay, also called a prolactin blood test, checks the level of prolactin in your blood. Prolactin is a hormone that helps with breast milk production. However, both men and women have prolactin in their bodies. Usually, the pituitary gland in the brain controls how much prolactin is made. Sometimes, the body makes too much or too little prolactin. This test helps find out if your prolactin levels are normal.
Why is a Prolactin Assay Done?
Doctors order a prolactin assay for several reasons. Often, they want to check for hormone problems. For example, high prolactin levels can cause symptoms in both men and women. Sometimes, the test helps find out if there is a problem with the pituitary gland. In other cases, it helps explain symptoms like irregular periods or trouble getting pregnant.
Symptoms and Conditions That May Require a Prolactin Assay
Many symptoms can lead a doctor to order a prolactin assay. For instance, women may notice changes in their menstrual cycle. Men may have trouble with sexual function. Sometimes, people notice breast discharge even if they are not breastfeeding. Because these symptoms can have many causes, a prolactin blood test helps narrow down the reason.
How is the Prolactin Assay Performed?
The prolactin assay is a simple blood test. First, a healthcare worker will clean your arm. Next, they will use a small needle to take a blood sample from a vein. The process takes only a few minutes. Afterward, you can return to your normal activities. Because the test is quick, most people find it easy to complete.
Preparing for the Test
Preparation for a prolactin assay is simple. However, there are a few things to keep in mind. For example, stress and exercise can affect prolactin levels. Because of this, doctors may ask you to rest before the test. Sometimes, you may need to avoid eating or drinking for a few hours. Always follow your doctor’s instructions.
Understanding Your Results
After the test, your doctor will review your prolactin levels. Normal ranges can vary by lab, but most adults have less than 25 ng/mL. High prolactin levels may point to a pituitary tumor, thyroid problems, or side effects from medicines. Low levels are less common but can also signal health issues. Because many things can affect prolactin, your doctor will explain what your results mean for you.
Risks and Considerations
Like most blood tests, a prolactin assay is safe. However, there are small risks. For example, you may have slight pain, bruising, or swelling where the needle went in. Rarely, some people may feel dizzy. Because these side effects are mild, most people recover quickly. If you have any concerns, talk to your healthcare provider.
