When do examinations expectant mother?

First examination

Pregnant woman at the doctor's officeThe first screening under normal conditions is scheduled for the eighth week after conception, but if necessary it can be postponed until the tenth week of pregnancy without any special consequences. If you do not know exactly what period of gestation you are in, you should consider the date of conception the first day after menstruation before their termination.

If menstruation does not stop during pregnancy, which is quite common, screening is usually carried out at week 8 after the estimated time of conception.

The first screening of pregnant women is intended to determine the compliance of the development of the fetus with the standards, as well as to establish the risks for the woman that may occur during the pathological course of pregnancy.

In addition, tests are necessary to identify the following serious incurable diseases:

  • Edwards syndrome - Trisomy 18;
  • Down's syndrome - Trisomy 21;
  • Congenital heart defect;
  • defects of internal organs;
  • defects in the development of the neural tube of the fetus.

If the screening shows the presence of certain problems, the doctor informs the woman about this, and also describes in detail the consequences of the development of one of these diseases.

Pressure measurementThe study begins with a general analysis of the state of the mother's body. The doctor carries out control weighing, as well as measuring the parameters of the body, to establish what was their dynamics over the past 3 months. Blood pressure indicators are also measured at this time, and if certain problems are observed, an ECG is also assigned, the results of which form recommendations for maintaining the proper level of health of the mother and child.

Screening involves the use of a number of tests - in particular, they include biochemical analysis of blood and check for STDs. If data on blood type are not available, they are also as accurately as possible established when the first screening is performed.

In addition, at this time, the first ultrasound is performed - it must be done to determine the compliance of fetal growth with the norms, as well as for the timely diagnosis of abnormalities in the development of the baby’s nervous system.During the ultrasound, the thickness of the collar zone is determined, the reduction of which may also be one of the signs of an increased likelihood of developing Down syndrome.

Ultrasound should be done to determine the causes of problems with the health of the mother - in particular, this type of study is prescribed for vaginal and uterine bleeding during pregnancy.

The future father of the child is examined by a doctorScreening usually involves screening a partner who is the future father of the child. Thanks to this, it is possible to establish the likelihood of the development of a hereditary genetic diseases in a baby, including incurable diseases, as well as having a very significant impact on human activity.

When it comes to problems such as sickle cell anemia, as well as thalassemia, during pregnancy a special regimen is prescribed to preserve the fetus. Also, genetic analysis in combination with ultrasound provides an opportunity to diagnose cystic fibrosis, which is a very serious problem for the child.

Second visit to the doctor

The second screening during pregnancy is already between 15 and 20 weeks from the moment of conception. Problems with determining the duration of pregnancy at this point should no longer be - during the screening at 8-10 weeks.When the second trimester comes to an end, further interventions in the child's development process, even if such soft ones as ultrasound, are considered highly undesirable. Therefore, it is very important to conduct all the necessary research up to the 20th week in order not to face many problems later.

The results of ultrasound in the hands of a womanThe second screening again includes a general analysis of the state of the mother's body to determine the dynamics of fetal development in another 3 months. In addition, an ultrasound is reappointed - however, this time not only the collar area is analyzed, but also all the limbs and organs that can be seen during such an examination.

If during the pregnancy there are problems associated with bleeding, as well as false contractions, it is this screening that may be the reason for the woman’s early leaving for the hospital, as well as for her hospitalization to save the fetus.

Before the start of the 3rd trimester, the doctor does four basic blood tests:

  • to determine the likelihood of damage to the spine of the child;
  • to identify genetic abnormalities;
  • to analyze the development of internal organs;
  • general biochemical blood test.
In combination with ultrasound screening, it is possible to determine an increased likelihood of developing Down syndrome with an accuracy of up to 80%. In addition, if we consider 3 other common problems associated with Edwards syndrome, heart disease and neural tube defects, then the probability of a successful early diagnosis of deviations reaches 100%.

If screening reveals a certain developmental anomaly of the fetus, or an increased likelihood of developing an incurable disease, the expectant mother is informed of the possible consequences. In addition, if the continuation of pregnancy is dangerous for the life of a woman, the doctor may also appoint an operation for medical reasons. Similar things happen when significant pathologies are identified.

Invasive research

What is sometimes called the “third screening during pregnancy,” is in fact a special operation, which is called the amniocentesis. Before the start of the 3rd trimester, it is very important to identify all possible abnormalities in the development of the fetus. To do this, in this period of pregnancy, a small amount of amniotic fluid is collected by inserting a thin needle through the abdomen.

Such screening, again, includes determining the likelihood of developing Down syndrome or Edwards syndrome. In addition, in combination with ultrasound 3, the study makes it possible to timely diagnose the splitting of vertebral arcs. If the hypothesis is confirmed, a cesarean section is assigned, which allows you to maintain the normal state of health of the child and the splitting is completely closed some time after birth.

With 3 screening there is a certain risk of miscarriage - the probability is about 0.5%. This should be taken into account by the mother - if certain pathologies of the course of pregnancy are observed, it is better to abandon the study. However, in no case should one avoid blood tests and ultrasound in order not to be left alone with such problems as serious incurable diseases. In addition, the doctor may himself indicate the presence of contraindications for 3 screening - but in any case, the woman should be familiar with the consequences of failure.

The introduction of the needle in the stomachAnother invasive study is carried out 3 months after conception - it is a chorionic biopsy. During this process, a small needle is inserted through the abdominal wall, which collects a sample of placental tissue.When there are certain genetic problems and abnormalities in the development of the fetus, including threatening abortion, this analysis allows for timely diagnosis. However, the second trimester still does not allow to make accurate conclusions - therefore, you will receive a forecast with an accuracy reaching only 60-70%.

After 3 months, the condition of the fetus is not yet stable, so even such a simple screening can disrupt it. It is worth remembering that the probability of miscarriage after a chorion biopsy is 1%. However, it is undesirable to refuse it - especially when ultrasound shows certain anomalies.

Do I have to undergo research?

Immediately it is worth mentioning that the screening of pregnant women in no case can not be forcibly carried out, and if a woman has certain reasons for refusal, she can tell the doctor about it.

However, experts recommend at least the first and second screening. 3 study, as well as chorionic biopsy, are no longer so important for the analysis of pregnancy and fetal development, especially if the ultrasound does not show certain abnormalities.

However, there is a list of individuals who are very strongly encouraged to undergo both the first and second screening. In particular, these include:

  • women who have previously had a miscarriage or fade of pregnancy;
  • those who have relatives with genetic diseases;
  • mothers of children whose father is a close relative;
  • women over the age of 35;
  • those who already have 3 children or more;

Expectant mothers who have suffered an aggressive disease of a bacterial or viral nature;

Women who smoked during pregnancy, used alcohol or used unwanted drugs.

The doctor makes the woman an ultrasoundThe minimum examination for them is ultrasound, during which you can identify most of the problems at the stage of the beginning of their formation. In addition, they are urged to undergo both invasive procedures to eliminate the risk of having a sick child.

There is also a list of women during which pregnancy screening may give incorrect results, amenable to incorrect primary interpretation. Carefully review it and do not rush to sound the alarm after receiving the results of the research, if you belong to one of the following groups:

  • women overweight more than 15 kg;
  • used IVF to fertilize the egg;
  • pregnant with two or more children;
  • patients with diabetes mellitus, as well as suffering from endocrine disruption.

In addition, the reason for obtaining incorrect results may even be a panic condition, which is often observed in women before the first examination during pregnancy.
