Determination of the level of prolactin (PRL)

Of particular importance is the level of PRL for pregnant women, since during the period of gestation and after the birth of a child, prolactin provides sufficient lactation, that is, the formation, accumulation, and secretion of breast milk by the mammary glands.

An analysis of prolactin is important for women who are just planning a pregnancy since the level of the hormone in the blood affects reproductive function, that is, the ability to conceive. So, an excess indicator sharply reduces fertility - a woman's ability to reproduce healthy offspring, as it causes a violation of the process of egg maturation.

A blood test for prolactin is prescribed by a doctor. One of the most common reasons for the diagnosis is a discharge from the mammary glands that are not associated with feeding the child. Such a deviation can be observed in women who have never become pregnant, men, and even children.

The level of the hormone can change under the influence of various circumstances. Therefore, it is necessary to prepare for the analysis of prolactin and follow all the recommendations of the doctor to obtain accurate results.

It will take 2-3 days to prepare. It consists of the following:

• It is necessary to exclude hard work, active sports, protect yourself from stressful situations.
• It is necessary to refuse to visit the sauna, bath, solarium.
• It is important to refrain from intimacy.
• It is necessary to exclude alcohol, heavy and fatty foods from the diet.

The prolactin test is usually scheduled for the morning. The interval between the last meal and the visit to the laboratory should be at least 8 hours. It is better to arrive 30-40 minutes before the appointed time, as doctors recommend being completely at rest for 25-35 minutes before the analysis.

Women should first consult a doctor to choose the most suitable day for sampling. This is because the phase of the menstrual cycle affects the result.

For the study, venous blood is needed. It is taken from the cubital vein by the puncture.
