That shows placental lactogen in pregnancy?

Waiting for the birth is a time for both joy and exciting. While the baby day by day is growing and developing, the mother is numerous studies in which doctors try to guess what is happening with the baby inside and if he was okay. Not always the results are accurate and reliable, so sometimes the interpretation can be an occasion for serious alarm. However, the calmness, only calmness.

There is Always the opportunity to re-analysis or to obtain a transcript from another specialist to compare the results. Today we will talk about what shows placental lactogen. This particular peptide hormone, which is produced only by the placenta. Accordingly, outside of pregnancy it in the blood is not detected. Today we will tell you what and on what terms can tell the specialist placental lactogen.

General description

First of all I want to say a few words about what constitutes this hormone. Doctors, of course, the idea about it, but to educate the future mother in no hurry. So, the placental lactogen is a chain of amino acids. In fact, growth hormone and prolactin are very similar to him. However, they are very different from each other. Today we are talking about hormone, which also possesses growth and Proektirovanie properties. While placental lactogen exhibits significantly higher lactogenic activity.

Basic functions

Our body will not do anything for nothing. This is especially true of procreation, everything must be clearly justified. Hormone placental lactogen plays a huge role in preparing the breast for feeding. It is synthesized from the earliest stages of pregnancy. Gradually, the level of this hormone in the blood increases and reaches its maximum in the 37th week. Before the birth of the indicators are significantly reduced.

I would also like to say that placental lactogen during pregnancy is studied, if a doctor, a leading pregnancy, have any suspicions about violations of the occurrence of ripening of fruit or the functioning of the placenta. The concentration of hormone in the blood is very variable. Therefore, it is important to focus not on averages but on individual body.

The Average norm

Numerous studies have allowed us to make approximate tables, which allow physicians to determine whether the pregnancy proceeds normal or suspect pathology. If the ultrasound shows a lag in the development of the fetus, it is recommended to be tested for placental lactogen. During pregnancy the norm depends on the term, which now is a woman. A small table allows a comparison of laboratory results with averages.

However, remember that these data are averages, so don't panic if your results are different. You can always get advice from a doctor who will allay your doubts. The more that specialist to diagnose always uses multiple research methods.

What does hormone

This is one of the most important issues. Indeed, what measure placental lactogen in pregnancy? That shows of this hormone? So, placenta – the only body which can develop. Therefore, it is the quantity of lactogen in the blood characterized by the condition of the placenta. Thus, if a woman is suffering with kidney abnormalities, there is a serious rise in this hormone in the blood. Hypertension, on the contrary, concentration in the blood is greatly reduced.

The First trimester the most important and challenging

Early stages of pregnancy are the most dangerous. However, in some studies it says that if the body tries to get rid of the fetus, then save it no need for a reason. But this does not negate the need to consult a doctor, as most importantly – to save the life and health of the mother. So, in the first trimester, the development of placental insufficiency and significantly reduced the level of PL. Extremely low indicators are revealed on the eve of fetal death and three days before spontaneous abortion.

But at a later time provides important information placental lactogen. The norm given above, and if the indicators are very different in the smaller side, it is possible to suspect renal insufficiency and chronic fetal hypoxia. We must not forget that the content of hormone in the blood may vary within a wide range, and most pregnant women, it is significantly lessnorm. However, when hypoxia of the fetus indicators are sharply reduced, approximately three times. The doctor, observing such a change, is obliged to smell a rat and take action.

Indications for examination

In some cases, doctors can send for analysis? Placental lactogen test for all pregnant women, but if indicators are normal, then again it is usually not retake. The exception – deterioration of pregnancy and other anxiety symptoms. Let's define the main indications for which the doctor may send you to the lab. If you are already in the later stages of pregnancy, and if there are complications. If the doctor thinks the fetus is lagging behind in development, he can evaluate the condition of the placenta and fetus through the study of a number of tests on the SUBMARINE.

Analysis results

The Amount of the hormone proportional to the size of the placenta. Therefore, the definition of level PL, it is advisable in pregnant women who belong to the risk group. So if history is diabetes mellitus or hypertension, it is likely that the doctor will prescribe the sample through the equal period of time. Additional testing is performed if there is suspicion of dysfunction of the placenta. It is important to note that levels of the hormone varies greatly, especially in the second half of pregnancy. Therefore, to confirm the result, it is recommended to define it multiple times.

Elevated levels of the hormone observed in a multiple pregnancy, rhesus-conflict and trophoblastic tumors. In addition, women with diabetes also often have changed the indices.

And in some cases it is Vice versa - the indices decrease. This often occurs when molar. This disease, which is characterized by a pathological development of the placenta tissue. In most cases, molar the fetus dies.

Choriocarcinoma – another pathology in which there has been a serious reduction of the hormone level. It is a malignant tumor of the uterus, which can develop as a result of normal delivery or abortion, and also result from hydatidiform mole. It is characterized by uterine bleeding and metastasizes to the liver and the brain.

Hypertensive toxemia – reduction in the level of PL, which precedes spontaneous abortion. And after 30 weeks in the determination of reduced levels you can say that there is a risk to the fetus. This may be a sign prezhdevremennaya birth, and fetal hypoxia. In both cases, physicians must assess the situation and prescribe treatment, and send to premature birth.

Conclusion

The Definition of "placental lactogen" can be completely unfamiliar for the woman who several times became a mother. This is easily explained by the fact that in the normal course of pregnancy, without serious concern for your baby's development, the doctor will appoint additional researches. However, if the results obtained are slightly different from the norm, there is no reason to panic. You will also need to undergo ultrasound to compare all previous surveys, and a week to repeat the analysis. Then we can draw a comprehensive conclusion.
