When prolactin take: what day of the cycle menstruatsionnogo donate blood when planning pregnancy, the blood of women, hormone analysis, when it is better, it is necessary, if possible, monthly, rules

A woman needs to know the value of prolactin in the body when to hand it analyzes which need training. Due to this the patient will be able to get true results of laboratory tests. Hormone production is regulated by the pituitary gland. Deviations from normal values ​​indicate the development of pathological processes on the part of the endocrine, genitourinary and ZN systems.

Why should a woman to know the level of the hormone

Prolactin is a hormone of the female reproductive system. It regulates the process of maturation of gametes during ovulation. At conception the substance stops the further maturation of follicles before birth. During lactation stimulates the production of breast milk. When harboring involved in the regulation of water-electrolyte metabolism, controls the synthesis of progesterone in the body.

Information about how and when to take venous blood prolactin will help early detection of violations in the body. Deviation from the norm hormone concentration indicates the occurrence of:

• mastitis;
• inflammation of the mammary glands;
• infertility;
• disorders of the reproductive organs work;
• low activity of brain glands: pituitary and hypothalamus;
• cardiovascular pathologies;
• failure menstruatsionnogo cycle;
• hormone imbalance due to incorrect operation of the endocrine glands.

Aims at donating blood gynecologist, endocrinologist or the therapist. The content of the hormone changes, not only due to pathological factors, but also because of the physiological processes in the female body. It is also recommended to be tested for the hormone when planning pregnancy through IVF or naturally.

Rent venous blood according to the duration of the cycle. Not all women, it lasts about a month. Blood on prolactin 1 shall once a year for routine inspection, to eliminate the risk of diseases of the reproductive system.

On what day of the cycle take

It is necessary to take prolactin in the afternoon or early in the morning, provided that the patient had not eaten for 6 hours. Doctors prescribe carrying out the procedure for 4-6 day menstrual cycle. During this period, other hormones are determined on the biochemical analysis: follicle, thyroid, luteinizing. All 4 of hormonal substances help to create a common clinical picture and show the cause of the pathological process in the reproductive system.

For routine preventive examinations take better prolactin in 26 day cycles. At this time, the amount of hormone rises due to ovulation and remains stable, therefore a high probability of obtaining reliable results.

When receiving oral contraceptives for laboratory examination performed on any day of menses. Hormonal treatments suppress the production of female sex hormones, so prolactin levels remained stable during the month. During the period of lactation for the week prior to the child's studies translate into a complete artificial feeding. During gestation does not matter the time of delivery of the biomaterial.

Why is the day of delivery

It is recommended to pass the prolactin on day 26 of the cycle. During this period, increased hormone production, there is the possibility of conception. During ovulation concentration of the substance increases, the body prepares for fertilization.

pituitary hormone level peaks in non-pregnant women and remains stable 2-4 days, so figure hormonal compound taken as the norm in this period.

The rest of the prolactin blood levels of low, non-permanent.

Preparation for delivery

Before you donate, a woman must be properly prepared and comply with the following rules:

• It is forbidden to eat, drink tea, coffee and carbonated soft drinks for 6-8 hours before the procedure;
• It is receiving a 500 ml still mineral water;
• you must refrain from smoking and drinking alcohol for 24 hours prior to the survey;
• refuse sexual intercourse, strenuous exercise, strength training, eliminate from the diet of protein foods;
• We need to avoid stressful situations, fatigue;
• to provide 8 hours of sleep;
• smoking conduct heat treatment: 72 hours before to be tested for prolactin, can not be subjected to sudden changes in body temperature;
• not recommended for screening for diseases of viral, fungal and bacterial origin;
• 48 hours as possible to cancel the use of psychotropic drugs, hormone pills and antibiotics.

Conducting research

Analysis of blood prolactin carried out in the morning from 8:00 to 10:00. This rule exists because in this period, the hormone concentration reaches the maximum value. Day of the serum level decreases. Daily fluctuations make it impossible to fix the normal content of the hormone in plasma.

In addition, a woman consumes food throughout the day. Increase in blood sugar and nutritional compounds contribute to the increase of prolactin. In extreme cases, can be taken on the day of the biomaterial analysis, but the study is not over 6-8 hours.

Norm on different days of the cycle

monthly cycle is divided into three main periods, in each of which strong hormonal changes. Because of this, there is a change in mood and well-being. prolactin level also varies depending on the phase:

1. Follicular. Characterized by an increase follicle size, formation of a new egg development which regulates prolactin. Norm substance at this stage of 4,1-30 ng / ml.
2. Ovulatory. After gamete maturation comes from a ruptured ovarian cells. Number pituitary hormone increases, ranges from 6 to 50 ng / ml. Thanks to the connection comes the possibility of conception.
3. Luteal. It lasts from the exit gametes into the uterus before the start of menstrual bleeding. Transformation occurs in the ruptured follicle corpus luteum. Prolactin begins to regulate the synthesis of progesterone. At conception, the contents of both hormones continues to increase. Prolactin women is essential for normal pregnancy and the production of milk in the breast. Otherwise, after a lapse of 7 days from the time of ovulation, its concentration decreases. The luteal hormone prolactin level period corresponds to 5-40 ng / ml.

Causes and treatment of abnormalities

If a woman passed biomaterial and get results with a high level of hormonal substances in the blood, it may indicate:

• constant mental and physical stress;
• engaged in heavy physical labor;
• substance abuse, alcohol or tobacco;
• in the presence of large amounts of dietary protein foods;
• coming conception;
• malignancy in the hypothalamus and pituitary;
• disorder of the thyroid gland;
• improper reception of psychotropic medicines that affect mood.

Increasing hormone possibly during the passage of hormone therapy in preparation for IVF when planning pregnancy. If the cause is the increased level of prolactin in pituitary disease process or the reproductive system organs, assigned reception glucocorticosteroids, thyroxine, pituitary blockers.

Prolactin in women is reduced in the background:

• tuberculous meningitis;
• radiation therapy;
• traumatic brain injury;
• benign and malignant tumors in the pituitary gland;
• pituitary apoplexy.

To stabilize prolactin indicators appointed medical therapy. Woman taking drugs based on artificial hormone analog. Conservative treatment is aimed at restoring the normal operation of the pituitary gland, the elimination of infections precipitating hormonal imbalance.
