Prolactin – what do your numbers mean?
Have you had your prolactin level measured and are unsure what the numbers mean? Here's a clear explanation of the normal range, what a high or low level might mean, and when it makes sense to get tested.
What is the normal range for Prolactin?
What is the normal range for Prolactin?
The normal range for prolactin varies depending on sex, age, and the laboratory's analysis methods. Generally, values for women are between 4-23 µg/L and for men between 3-15 µg/L. In pregnant women, levels can be significantly higher, often up to 200-400 µg/L. It's important to note that reference intervals can vary between laboratories, and factors such as diurnal variation and stress can affect measurements. Being close to the limit may indicate a need for further investigation, especially if there are symptoms like menstrual irregularities or infertility.
What does a low level mean?
A low level of prolactin can be a sign of hypopituitarism, where the pituitary gland does not produce sufficient amounts of hormones. It can also be caused by pituitary infarction, known as Sheehan's syndrome, which is often seen after complicated births. Symptoms can include fatigue, weight loss, and an inability to breastfeed. Individuals with low prolactin should contact a doctor for further assessment and possible treatment, as the condition can affect other hormonal functions.
What does a high level mean?
A high level of prolactin, also called hyperprolactinemia, can lead to symptoms such as menstrual irregularities, decreased libido, infertility, and in men, impotence or gynecomastia. Causes can include pregnancy, medications such as antipsychotics, hypothyroidism, or prolactin-producing tumors in the pituitary gland. Treatment depends on the cause and may include medical therapy or surgery. It is important to seek medical attention if you experience symptoms, as untreated hyperprolactinemia can have serious consequences.
