Prolactin is a hormone made by the pituitary gland, a small gland at the base of the brain. It is best known for stimulating milk production in the breasts during and after pregnancy, but it is present in both women and men. This test measures the amount of prolactin in the blood. This test is often used to help evaluate the cause of irregular or absent menstrual periods, infertility, and unexpected breast milk production. In men it may be used when looking into low testosterone, reduced sex drive, or erectile difficulties. It can also help detect and monitor a type of pituitary growth called a prolactinoma and to check the effect of certain medications on prolactin levels.

Guides about Prolactin

Plain-English explanations of what this test measures and how it's done.

Infertility on TRT: What to Monitor
Testosterone replacement therapy (TRT) often lowers sperm production, because testosterone from outside the body tells the pituitary gland to cut back on LH and FSH, the two signals the testicles need to make sperm. The measurements used to follow this are a semen analysis, which is the direct measure, plus blood levels of LH, FSH, testosterone, estradiol and prolactin.
What is a semen analysis?
A semen analysis measures the volume of a semen sample and the number, movement and shape of the sperm in it. It is the main lab test for male fertility, and it is not a blood test: the sample is collected at a clinic or lab, or at home and delivered within 30 to 60 minutes. Blood-test ordering services don’t sell it, but they do sell the hormone tests often ordered alongside it.

Prolactin: common questions

How much does a Prolactin test cost without insurance?

The lowest self-pay price we track for Prolactin is $8.57 at Mito Health, across 17 ordering services; the highest is $79.00. You pay the ordering service directly, and no insurance is involved. Prices were last verified on September 28, 2026.

Do you need a doctor's order for a Prolactin test?

No. Every ordering service listed on this page includes the physician order with the purchase, so you can buy Prolactin yourself and take the requisition to the lab. Your results come back to you — what they mean is a conversation for you and a clinician.

Where is the blood drawn for a Prolactin test?

At a Quest Diagnostics or LabCorp patient service center, depending on which laboratory the ordering service you pick uses. You choose the location and time after you order. LabTestCompare does not draw blood, run tests, or issue results — we only compare what each service charges.

Can you use health insurance for a Prolactin test?

No. Every price on this page is a self-pay price paid directly to the ordering service, and none of these services bill insurance. If you want Prolactin billed through your plan instead, that goes through your own provider — which is a separate route with its own cost, and worth comparing against the prices here.

Is this the same Prolactin test a doctor would order?

Yes — it is the same assay, identified by the same laboratory order codes: Quest #746 and LabCorp #004465. Every price on this page is matched to that code, which is how we can say the services are being compared on an identical test rather than on similarly named products.

How long do Prolactin results take?

That is set by the laboratory rather than by us. Routine blood tests are commonly back within a few business days and specialized assays take longer; the ordering service states the expected turnaround for Prolactin before you buy, and delivers the result to you directly.
