The list of the weeks will be presented to your attention below. This article will tell you about the features of conducting a particular study.

What is it for?
Before you start taking tests during pregnancy (a list of weeks will give you a gynecologist), you need to know what it's for.
In ancient times, medicine was unable to determine the state of the child in the womb. The only thing that obstetricians did was to test the fetus on late pregnancy and determine its heart rate. It is worth saying that in these cases, women and doctors relied on luck. That is why children with deviations and congenital pathologies often appeared in the world. Over the years, everything has changed a lot.
Currently, medicine has made a big step forward. Now every representative of the weaker sex must take tests during pregnancy. Such studies help determine its condition and dynamics in the development of the baby. If there are any deviations, there is a high probability of successful adjustment. Consider what tests are given during pregnancy. A list of the weeks will help you not to miss any of them.
Supervision of pregnancy begins from the very moment when a woman turns to a medical institution. Typically, the fairer sex will learn about their new position in about five weeks. However, at this time, doctors are not yet registered. All due to the fact that the early periods are characterized by interruption of pregnancy in about 20 percent of cases. This does not mean that the visit will be useless. When contacting a woman's consultation, the doctor will tell you which tests to take during pregnancy. Also the gynecologist will take from you a smear from the vagina and write out the necessary directions. Among them, you can isolate the analysis of blood, urine and feces. Passage of specialists, ultrasound research, measurement of parameters and interrogation. Let us consider these points in more detail.
Diagnosis of blood
What tests are given by a woman when registering for pregnancy? This includes a general blood test, a biochemical study, a definition of the Rh factor and a group. It is also necessary to conduct a diagnosis of coagulation and coagulation. In addition, the fairer sex will have to donate blood for HIV, syphilis, hepatitis B and C, various infections that can be transmitted through sexual intercourse.
The material is taken from the vein. Sometimes for a common analysis, blood is taken from the finger. It should be noted that before the diagnosis you can not eat food. A few days before this, it is necessary to exclude fatty foods and alcoholic beverages from the diet.
When registering from the 5th to the 9th week of pregnancy, a woman must pass urine several times for diagnosis. First, a general study of the material is made. If poor tests are determined during pregnancy, the doctor recommends an additional diagnosis. To do this, we write out the directions for bacteriological culture, the analysis according to Nechiporenko, Zimnitskii, and so on.
It should be noted that in each case it is necessary to follow certain rules for the collection of material. For a general study, it is preferable to use the morning total urine sample after performing hygienic manipulations.
Passage of specialists
When registering for the first trimester of pregnancy, it is necessary to visit specialists. Most often gynecologists require a conclusion from a cardiologist, oculist, otorhinolaryngologist, dentist and therapist. If necessary, ultrasound examination of the kidneys, thyroid and heart.
The necessary tests for pregnancy include ultrasound diagnosis. The first study is conducted at a period of 10-13 weeks. During this period, the study can be performed by a transvaginal sensor or through the abdominal wall. Everything depends on the device and the doctor's qualification.
During the diagnosis, the expert evaluates the size of the embryo and fetal egg. It also determines the location and quality of its fastening. Ovaries, the cervix and the cavity of the genital organ must be examined. According to the data obtained, the exact gestation period and the estimated date of delivery are determined.
In the second trimester
What tests should I take in the second trimester of pregnancy? At this time, a very important study is being carried out, which is called screening. In most cases, doctors set a period of 18-22 weeks. However, some experts say that it is more informative to conduct the analysis in 16 weeks.
Screening includes a blood test for the amount of chorionic gonadotropin. This substance can indicate possible vices of intrauterine development and reveal some syndromes. Also at this stage, another study is carried out using an ultrasonic sensor. The specialist during the analysis examines the placenta, determines the size of the fetus and its position. It is worth saying that after 20 weeks you can already determine the sex of the future baby with great accuracy.
After 30 weeks of pregnancy, a woman goes on maternity leave. This moment is waiting for many future moms. However, the third trimester is characterized not only by this event. At this stage of fetal development, the representative of the weaker sex has to undergo a lot of research.
In the period from the 30th to the 35th week, the woman is assigned repeated consultations of specialists. As you already know, this includes a dentist, an ENT, a therapist and a cardiologist. Also, at 29-30 weeks pregnant woman should take a blood test for HIV, syphilis, hepatitis. A general analysis and a biochemical study are mandatory.
At about 32 weeks, a woman should take a swab from the vagina to determine its purity. Also from this date, an additional study, which is called cardiotocography, begins. It is produced from 1 to 3 times. However, if a deviation is detected, it can be scheduled every week.
The last ultrasound
Before giving birth, a woman must go to the third ultrasound examination. It is held on the period from the 32nd to the 36th week. During the analysis, the specialist determines the position of the fetus and the level of maturation of the placenta. Also, the umbilical cord is examined and the doppler of the vessels is performed.
Based on the results of this study, some future mothers are assigned a cesarean section.
Norms of tests during pregnancy are always individual for each term. That's why you should not try to decipher the data yourself. It is worth noting that, in addition to the above described tests, a woman must regularly take urine for diagnosis. This is done before every next reception. At the very beginning of the term, the expectant mother visits the gynecologist once every four weeks. Further, after 20 weeks of pregnancy, the visit is applied in two weeks. In the third trimester the gynecologist wishes to see the expectant mother in her office once in seven days. And so on until the very birth.
Try to regularly give prescribed tests to you. Remember that even with good health sometimes develop pathologies in the baby. Observance of the terms of the examinations will help you in time to identify deviation from the norms and carry out a correction. Trust your gynecologist. Mild pregnancy and good health!
