A prolactin test is a blood test that measures the amount of prolactin in your blood.
Understanding Prolactin
Prolactin (PRL) is a hormone produced by the pituitary gland. This gland is located at the base of your brain. Hormones like prolactin act as chemical messengers. They travel in the bloodstream to control the activities of specific cells or organs in your body.
What Does a Prolactin Test Measure?
- Blood Sample Analysis: The prolactin test involves taking a small sample of blood, usually from a vein in your arm. This blood sample is then analyzed in a laboratory.
- Hormone Level: The test specifically measures the concentration of the prolactin hormone present in the blood. The reference indicates that it "measures the level of prolactin in a sample of your blood."
- Diagnostic Tool: The results of this test can help healthcare providers understand if your prolactin levels are within the normal range. Abnormal prolactin levels can indicate various conditions that might require further evaluation.
Why is a Prolactin Test Done?
A prolactin test might be recommended if you are experiencing symptoms that could be related to abnormal prolactin levels. These symptoms may include:
- Infertility: In both men and women, high prolactin levels can sometimes cause infertility issues.
- Galactorrhea: This refers to the production of breast milk outside of pregnancy or breastfeeding.
- Menstrual Irregularities: In women, high prolactin can cause changes in the menstrual cycle.
- Erectile Dysfunction: In men, elevated prolactin can lead to erectile dysfunction and decreased libido.
- Headaches and Vision Problems: Sometimes, pituitary tumors causing high prolactin may also lead to these symptoms.
