Special Instructions
How to prepare for your test
Prepare for your Prolactin Blood Test by following these instructions. Avoid vigorous exercise or sexual activity for 48 hours beforehand, as these can raise your prolactin levels. Avoid nipple stimulation or heavy meals before taking the test, as these can increase prolactin levels. For tests that include prolactin, take your sample before 10 am and at least an hour after waking. Do not take biotin supplements for two days before this test, discuss this with your doctor if it is prescribed.
FAQ’s
-
Prolactin is a hormone which is produced in the pituitary gland and plays a role in reproductive health. Its primary purpose is to stimulate milk production after childbirth, and in pregnant and breastfeeding women prolactin levels can soar.
In men, prolactin helps with:
Regulating testosterone production
Supporting Sperm development
Influencing sex drive and overall reproductive health
Playing a role in the immune system

A prolactin blood test measures the level of prolactin, a hormone produced by the pituitary gland, in your blood. Prolactin plays a key role in milk production (lactation) and can also influence your menstrual cycle, fertility, and even your mood. Here's what a prolactin test can help assess:
1. Lactation Issues:
High Prolactin Levels: Excess prolactin (hyperprolactinemia) can lead to problems such as unexplained milk production (galactorrhea) in women who aren't breastfeeding, or it may cause infertility in both men and women. In women, it can cause irregular periods or stop menstruation altogether.
Low Prolactin Levels: This is less common but can affect breastfeeding ability after childbirth.
2. Infertility:
High prolactin levels can interfere with ovulation and reduce fertility, making it harder to conceive. Both men and women can be affected.
3. Pituitary Gland Disorders:
Prolactin is produced by the pituitary gland, so abnormal levels can indicate a pituitary tumor or other disorders (like a prolactinoma). This can lead to headaches, vision problems, or changes in hormone levels.
4. Hypothyroidism:
Underactive thyroid (hypothyroidism) can also cause elevated prolactin levels, so this test can sometimes be part of a broader thyroid function evaluation.
5. Medications:
Certain medications (e.g., antipsychotics, antidepressants, blood pressure drugs) can increase prolactin levels, so if you're on medications, your doctor may use this test to assess if they’re affecting your prolactin.
6. Other Conditions:
Conditions like kidney disease, liver cirrhosis, and stress can also influence prolactin levels.
A prolactin test can be especially useful if you're experiencing unexplained symptoms related to reproduction, lactation, or hormonal imbalances. If your levels are abnormal, further tests may be needed to determine the underlying cause.
