What's this test for?

This test is ideal if you're experiencing irregular or absent periods, unexpected breast milk production when you're not pregnant or nursing, or fertility challenges. It helps identify hormonal imbalances that may be affecting your reproductive health, sexual function, or causing unexplained symptoms. Many people use this test when they suspect their hormones are off but want concrete answers about what's happening.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your prolactin levels mean for your reproductive health, menstrual cycles, and overall hormonal balance. These notes include personalized recommendations like lifestyle changes, stress management techniques, or whether you should consider follow-up testing or consultation with an endocrinologist. You'll also get the standard lab report and can track your prolactin levels over time using our trends feature to see how your interventions are working.

What's included in this test?

This test measures both total prolactin and monomeric prolactin. Total prolactin shows the overall amount in your blood, while monomeric prolactin (the active form) helps identify if elevated levels are truly causing symptoms or if it's a harmless condition called macroprolactinemia. This two-part approach ensures you get accurate results and avoid unnecessary treatment.

Who should consider getting this test?

This test is important for women with irregular or missed periods, unexplained infertility, or unexpected breast milk production. It's also helpful for people experiencing decreased sex drive, erectile dysfunction, or symptoms of hormone imbalance. Anyone taking medications that can affect prolactin levels or being monitored for a pituitary condition should consider this test.

What symptoms indicate I may need this test?

Common symptoms include irregular or absent menstrual periods, difficulty getting pregnant, unexpected breast milk production when not breastfeeding, and reduced sexual desire. You may also experience headaches, vision changes, breast tenderness, or vaginal dryness. In men, symptoms can include low testosterone, erectile dysfunction, and reduced body hair.

When will I get my results?

Most prolactin test results are available within 1-3 business days after your blood sample reaches the lab. You'll receive an email notification as soon as your results are ready to view in your secure online account. Complex cases or tests requiring additional analysis may occasionally take a bit longer.

What is prolactin and why does it matter?

Prolactin is a hormone produced by your pituitary gland that primarily controls milk production after childbirth. However, it also plays important roles in reproductive health, menstrual cycles, and sexual function for both men and women. When prolactin levels are too high or too low, it can disrupt ovulation, cause irregular periods, affect fertility, and impact your sex drive.

What does high prolactin mean?

High prolactin levels can prevent ovulation and cause irregular or missed periods, making it harder to get pregnant. It can also cause unexpected breast milk production, reduced sex drive, and vaginal dryness in women, or erectile dysfunction and low testosterone in men. Common causes include stress, certain medications, pituitary tumors, or thyroid problems.

How can I naturally support healthy prolactin levels?

Managing stress is crucial, as stress can significantly raise prolactin levels, so try meditation, yoga, or regular exercise. Ensure you're getting adequate sleep and consider reducing high-intensity exercise if you're overtraining. Foods rich in vitamin B6 like fish, poultry, and bananas may help regulate prolactin, and some people find that vitex (chasteberry) supplements help, though you should discuss this with your healthcare provider first.

How often should I retest my prolactin levels?

If your initial test shows elevated prolactin, your doctor will typically want to retest within a few weeks to confirm the results, as levels can fluctuate with stress and other factors. If you're being treated for high prolactin, retesting every 3-6 months helps monitor whether treatment is working. Once your levels stabilize, annual testing may be sufficient for ongoing monitoring.
