Brief Details
What Is a Prolactin Test?
A prolactin test, also known as a PRL test, is a simple blood test that measures the level of prolactin hormone in your bloodstream. Prolactin is produced by your pituitary gland, a small but important gland located at the base of your brain.
The test uses a blood sample drawn from a vein in your arm. This test helps detect conditions related to abnormal prolactin levels, which can affect your reproductive health and indicate potential pituitary gland disorders.
What Does the Prolactin Test Measure?
The prolactin test measures the concentration of prolactin hormone in your blood to help doctors understand your hormonal health:
- Investigate irregular or absent menstrual periods in women.
- Determines potential causes of infertility in both men and women.
- Identifies the reason for unexpected milk discharge from breasts when not pregnant or breastfeeding.
- Diagnoses and monitors prolactinoma (a non-cancerous pituitary tumour).
- Evaluates symptoms like low sex drive or erectile dysfunction in men.
- Monitors treatment effectiveness for prolactin-related conditions.

Why Is a Prolactin Test Done?
The PRL test serves as a crucial diagnostic tool to identify hormonal imbalances affecting reproductive health and helps doctors diagnose conditions like pituitary tumours, guiding appropriate treatment decisions.
Importance of a Prolactin Test
The prolactin test plays a vital role in women's and men's health by identifying treatable causes of fertility and reproductive issues. High prolactin levels are a common yet manageable cause of infertility, making early detection essential for successful treatment. This test directly helps diagnose prolactinoma, the most common hormone-producing pituitary tumour.
Early identification allows timely treatment that can restore fertility, regulate menstrual cycles, and relieve symptoms like headaches or vision changes. Prolactin test results guide treatment plans and help monitor how well medications are working, ensuring you receive the most effective care for your specific condition.

|
Prolactin |
4.79-23.3 ng/mL
|
Prolactinoma, hypothyroidism, kidney disease, liver disease, polycystic ovary syndrome, other pituitary disorders, anorexia nervosa |

Conditions that May Affect Prolactin Test Accuracy
Several factors can influence your prolactin test results and should be discussed with your doctor:
- Certain medications, particularly antipsychotics, antidepressants, and blood pressure medicines, can raise prolactin levels.
- Physical or emotional stress can temporarily increase prolactin.
- Strenuous exercise within 24 hours before the test may affect results.
- High-dose biotin supplements (>5 mg/day) can interfere with certain immunoassay methods such as ECLIA; avoid for at least 8 hours before testing.
- Pregnancy and breastfeeding naturally elevate prolactin levels.
- Prolactin levels show a diurnal pattern—highest during sleep and early morning—so blood collection should ideally be done 2–3 hours after waking.
How Is a Prolactin Test Done?
The prolactin test follows a standard blood collection procedure that is quick and straightforward:
- A healthcare professional cleans the area on your arm with an antiseptic.
- An elastic band is tied around your upper arm to make the veins more visible.
- A small needle is inserted into a vein, usually in your elbow area.
- A small amount of blood is collected into a special tube.
- The needle is removed, and a cotton ball or bandage is applied to prevent bleeding.
- Your blood sample is sent to the laboratory for analysis using advanced testing methods.
How Should You Prepare for a Prolactin Test?
Proper preparation helps ensure accurate test results:
- Schedule your test 2–3 hours after waking for optimal timing.
- Avoid strenuous exercise and stressful situations for 24 hours before the test.
- Rest for 30 minutes before your blood collection.
- Avoid high-dose biotin supplements (>5 mg/day) for at least 8 hours before the test.
- Inform your doctor about all medications you're taking, as some can affect prolactin levels.
- No special diet restrictions are needed for this test.
