A prolactin blood test measures the level of prolactin, a hormone produced by the pituitary gland. It can provide useful information about hormonal and reproductive health.
Abnormal prolactin levels may affect ovulation, menstrual cycles, and fertility. Testing may therefore be recommended during a fertility assessment or before treatments such as IVF or IUI.
At Luna Fertility, we offer convenient fertility blood testing in London, helping you understand your hormone levels and take the next step in your fertility journey.
A prolactin blood test is a simple blood test that measures the amount of prolactin in your blood.
Prolactin is a hormone produced by the pituitary gland and is mainly involved in breast milk production.
Prolactin also plays a role in reproductive health. Higher-than-normal levels may affect ovulation, menstrual cycles, and fertility, which is why the test may be included in a fertility assessment.
At Luna Fertility, prolactin testing can help provide a clearer picture of your hormone levels, particularly if you are experiencing fertility concerns or preparing for fertility treatment.
At Luna Fertility, we make prolactin testing simple and convenient, with a fertility-focused approach designed around your reproductive health.

Attend your scheduled appointment at the Luna Fertility clinic in London. Your healthcare professional may ask about your cycle, medicines, fertility history, and symptoms.
You will also receive any preparation instructions before your test.
A trained healthcare professional will collect a small blood sample, usually from a vein in your arm. The process only takes a few minutes.
Your sample is then sent to the laboratory to measure your prolactin level.
Once your sample has been analysed, you will receive your prolactin test results with the laboratory’s reference range.
Your healthcare professional can explain the result and advise if further testing or fertility assessment is needed.
Prolactin results are usually reported in mIU/L or ng/mL, depending on the laboratory.
There is no single number that is considered normal for everyone. Reference ranges vary between laboratories, and pregnancy and breastfeeding can significantly increase prolactin levels.
The table below provides a general guide rather than a diagnostic reference range:
| Prolactin Level | Interpretation | What It May Mean |
|---|---|---|
| Within range | Usually normal | No clear sign of high prolactin |
| Mildly high | Slightly raised | May be linked to stress or medicines |
| Moderately high | Above normal | May affect ovulation or periods |
| Significantly high | Much higher than normal | May need further testing |
| Low | Below normal | May need review with other results |
