Prolactin analysis: what day of the cycle to take, the indicators of the norm
A complex human body depends on a coherentwork of all organs and systems. Failure in the functionality of any one body entails a huge number of problems. For example, with certain diseases, hormone analysis is needed. And because often you can hear a question from women: "And prolactin on what day of the cycle to take?".
The hormone prolactin
Hormonal (endocrine) system of manresponsible for all processes occurring during life. The main organ of this complex organization is the pituitary gland. It is here that prolactin is produced. What is it with women? It is a hormone necessary for the growth of the female breast and lactation.
It is interesting that, despite the fact that it would seem,absolutely feminine destination, prolactin is produced by the pituitary gland of men. However, all the functions of this component of the group of lactin-like proteins have not yet been fully studied. So this hormone is produced in a certain amount throughout the life of a person.
Everyone heard about biorhythms. Many may even feel certain changes in the body based on such rhythm. That's the production of the hormone prolactin is subject to such fluctuations. They depend on a variety of reasons that can both increase and decrease the production of this hormone.
For women, a characteristic increase in outputProlactin occurs during pregnancy and lactation of the newborn. But for both women and men, its production can significantly increase due to depression, stress, psychosis, anxiety, severe pain. Affect the increase in the production of prolactin and large doses of alcohol, drugs, some antidepressants, antipsychotics, tranquilizers, normotimics.
Most contraceptives,Estrogen and some drugs that help fight vomiting also provoke the production of prolactin in larger quantities. But the intake of glucocorticoids, antagonists and hormones of the thyroid gland reduces the production of this hormone. That is why in certain situations, an analysis of prolactin is necessary. Where to hand over and how, tells the attending physician, appointing such a survey.
The main purpose of prolactin is workmammary glands and the activity of the apparatus of reproduction of the human body. With the onset of sexual development, its production increases, reflecting on the development of the breast, ducts, the formation of a mammary gland capable of producing milk for feeding a newborn baby.
Scientists have established that education in itselfprolactin has no effect on milk production, but this hormone is responsible for its formation, the amount in the mammary glands of the mother. The entire process of procreation is built on the hormones and cyclicity of certain processes in the body of a woman. That is why conducting some studies depends on menstruation. "Analyzing for prolactin on what day of the cycle to take?" - this question is of interest to those women who are prescribed a similar examination by a doctor.
Feeding the baby with breast milk is the mainthe ability to strengthen the immunity of a newborn baby. The first months of life this is how he gets all the necessary nutrients. And the production of colostrum and milk is a complex process in which many reactions are associated. A considerable role here is played by prolactin.
This hormone, though it has no effecton the very process of separating milk from the breasts of a woman, but it works on the production of colostrum, its quantity, maturation and transformation into milk. According to some reports, it is because of the presence of prolactin in a significant amount during lactation that a woman can not become pregnant - the hormone acts as a contraceptive.
The hormone prolactin is needed not only for womenin order to be able to breast-feed the baby. It is produced in men. Scientists have found that prolactin plays a role in the work of the immune system, in regulating the water-electrolyte balance of the human body. It is an important element of the entire endocrine system.
But for the qualitative work of prolactin shouldproduced in a certain amount. So, the increased level of prolactin in men causes problems in sexual life - the feeling of libido decreases, the quality of sperm decreases, in which the quantity of spermatozoa decreases. Therefore, men may also be interested in the question: "Why should I give prolactin?"
What is the purpose of analysis?
Some states of the human body,diseases in their basis have a violation of the hormonal balance. And the analysis on hormones in certain situations will help to establish the cause of malaise, some violations, and therefore, to choose the right treatment. So, to determine the level of the hormone prolactin, you need to donate blood to determine the level of its content. The most frequent reasons for the appointment of such a survey are:
- abnormal discharge from the chest, both in non-pregnant and non-immune women, and in men;
- pain in the mammary glands;
- chronic inflammation of the genital area;
- menstrual cycle disorders;
- decreased libido;
- menopausal disorders in severe form.
The analysis on prolactin is also part of thecomplex hormonal research. For women, when assigning such an analysis, the question arises: "Prolactin on what day of the cycle to take?". The answer to it will be given by the doctor who prescribes the examination.
Preparation for the prolactin assay
On how to properly pass the test for prolactin,think everything to whom such a survey is appointed. In preparation, there is nothing unfulfillable. For women who are not pregnant, blood donation to prolactin is necessary on the 5th-8th day of the cycle. There are also several general recommendations that are not dependent on the patient's sex:
- to exclude sexual contacts one day prior to the analysis;
- Exclude visiting saunas and steam rooms a day before donating blood to the hormone prolactin;
- exclude increased physical activity a day before the analysis;
- It is not recommended to eat fatty foods and alcohol a day before the test;
- one hour before blood sampling, do not smoke;
- be in a calm emotional state;
- blood donation to prolactin is necessary in the morning, no later than 3 hours after awakening;
- The analysis is given on an empty stomach, you can drink only water.
Dependence on the monthly cycle
Women who do not expect the baby to be born in the next9 months, with the appointment of the analysis is always interested in what day of the menstrual cycle give prolactin. It is best to take this examination between the 5th and 8th day of the menstrual cycle. Some clinicians believe that the level of prolactin depends little on the rhythm of menstruation and can be easily recalculated depending on the day of menstruation. But it's better to come to the analysis in the first days of the cycle to get the most accurate results.
The endocrine system is complex and multifunctional,it controls all the processes occurring in the human body, and failures in its work lead to many health problems. The same applies to a specific hormone, such as prolactin. The norm in women by age and in men is determined by numerous studies. But one should always take into account the fact that its level can fluctuate even depending on the mood and emotional state of the subject. In more detail tell about the level of a hormone, such as prolactin, the table below.
|age||men, md / ml||women, medlm|
|1-12 months||less than 607||less than 628|
|over 1 year old||73-407||109-557|
It is characteristic that in newborns the levelProlactin in the blood is initially high. This is due to the presence in the womb of the mother, whose body is preparing for childbirth and the period of lactation. Within a month or two, this figure is significantly reduced. The gradation in the level of hormone for patients over 1 year is associated with many factors, including the psychoemotional attitude toward the procedure for blood sampling. The answer to the question: "The analysis on prolactin where to hand over?" simple - in a medical institution that accepts such tests.
If the indicator is above the norm
The level of prolactin in the blood of a person inthe approximate norm has a wide enough range, because its production is intensified for many everyday reasons, even an evening plentiful supper or a cigarette smoked in the morning will have an impact on the indicators. But with certain health problems, the level of prolactin will be high even if all the requirements for preparing for the analysis are met. Exceeding the norm of prolactin in the blood of a person makes it possible to assume the following:
- Some diseases of the hypothalamus that cause active hormone production;
- pituitary disease, responsible for the production of prolactin;
- a disorder in the functioning of the adrenal cortex;
- renal insufficiency;
- diseases of the female genital area, for example, polycystic ovaries;
- decreased thyroid function;
- anorexia nervosa;
- use of certain medications.
Also, an increase in the level of prolactin in the blood is characteristic of pregnancy.
If the indicator is below the norm
For women, the question is: "Prolactin on what day of the cycle to take?". The analysis of blood on the 5th-8th day of the menstrual cycle will give the most accurate results of such a survey. Although the level of prolactin in the blood can fluctuate for many reasons, its significant decrease indicates possible health problems for both women and men, such as:
- tuberculosis of the pituitary gland;
- Shihan syndrome (apoplexy of the pituitary gland);
- neoplasms of the brain, including malignant ones;
- taking certain medications;
- craniocerebral trauma;
- radiation therapy.
The decrease in the level of prolactin in the blood of a pregnant woman speaks of a delayed pregnancy and the need to take certain measures for the birth of a child.
Pathology and prolactin
The level of the hormone prolactin in humans has onefeature - it has a very wide range of indicators, considered to be the norm, and the level change occurs for many reasons, quite common - overeating, smoking, stressful situation, poor sleep.
Control of prolactin in the blood is necessary formedical indicators, because a stable change in the amount of this component of the endocrine system can cause disruption in the work of the whole organism as a whole, for women, for example, cause infertility. In men, the change in the level of prolactin in pathological boundaries is extremely rare. Increased or decreased levels of prolactin require re-examination after 10-14 days to confirm the result. Then a comprehensive examination is conducted to determine the cause of the violation of the level of the hormone in the blood.
Treatment for reducing prolactin levels in men and women
One of the important hormones is prolactin. What is it with women? This substance is produced by the endocrine system, which contributes to the development of the mammary glands, the production of milk for the feeding of the child. The role of prolactin has not been sufficiently studied, but scientists have found that it exerts a tremendous influence on all organs and systems of the human body. Therefore, violations of its production cause many health problems.
The change in the level of prolactin in the blood of menis rare. But for women such a pathology is a frequent phenomenon. Treatment of hyperprolactinemia is carried out in accordance with the cause that caused it. The attending physician after diagnosis can prescribe a hormonal adjustment, treatment of the tumor with the help of radiotherapy, surgical intervention.
All methods of treatment should correspond to the condition of the patient, take into account both the disease itself, and concomitant diseases, anamnesis, possible contraindications to the chosen method of eliminating the problem.
For each person the problems of the endocrine system- a frequent cause of the emergence of diseases and pathological conditions. Therefore, regular medical examination, the delivery of the necessary tests will help to maintain health, improve the condition. To determine the causes of ailments, the often prescribed analysis is prolactin. On what day of the cycle to take it - an important issue for women.
Although many doctors believe that it is herea specific day of menstruation does not play any role, it is still best for the correct results to come to the survey on the 5th-8th day of the cycle. If the results do not correspond to normal parameters, a second examination is carried out after two weeks. Then the doctor decides on further examination to determine the cause of prolactin level disorders.
