Understanding the test results of Prolactin Test

Prolactin levels in pregnant women and lactating mothers are typically high. Non-pregnant women and males usually have low levels. If your prolactin levels are more significant than average, you may have a prolactinoma, a form of pituitary tumour. The gland produces too much prolactin as a result of the tumour.

Why do I need a Prolactin Test?

You can examine prolactin levels at any time throughout your menstrual cycle. Prolactin levels fluctuate throughout the day, but they are most significant at night and first thing in the morning; thus, the test is typically done three hours after you get up.

What happens during the Prolactin Test?

The physician or medical specialists use a tiny needle to obtain a blood sample from a vein in your arm. Once the needle is inserted, a small quantity of blood will be collected in a test tube or vial. It may hurt a bit while they discharge the blood. The prolactin test results will be in the form of a number after a few days.

What is the normal range of prolactin in a woman?

The reference range of normal prolactin blood levels differ across sexes, ranging from 4-23 ng/mL (mcg/L) in non-pregnant adult women to 3-15 ng/mL in males.

SEXES

    NORMAL PROLACTIN LEVELS (mcg/L)

Men: 3-15 ng/mL
Non-pregnant women: 4-23 ng/mL
Pregnant women: 34-386 ng/mL 
Children: 3.2-20 ng/mL

Prolactin levels in women differ somewhat depending on the stage of the menstrual cycle. During pregnancy, levels rise to up to 20 times their typical levels before birthing.

What causes prolactin levels to be high?

Prolactin levels that are too high might cause weight gain and cognitive problems. Prolactin is associated with growth and increased body weight, regardless of a substantial influence on hypothalamic or pituitary function. Weight reduction was observed in 70% of prolactinomas patients and 90% of male patients who had their prolactin levels adjusted in this study.

A high level of prolactin can cause medication, several types of pituitary tumours, an underactive thyroid gland, prolonged chest pain, pregnancy, and lactation.
