Screening during pregnancy

Screening during pregnancy photos If you ask for interpretation to the encyclopedia, we there read what screening - it is a method for identifying individuals with disorders and factors that led to its development, aimed at the use ofdiagnostic tests, including tests.

screening is carried out with one purpose - early diagnosis of the disease and determine the predisposition to any disease that requires, in turn, timely treatment and preventive care.The results come in the screening study of the disease under study, as well as the possible groups of diseases.

One of the basic conditions during the screening of pregnant women is the availability of well-trained personnel, as well as the standard approach for the identification of the test attribute in the evaluation of the results.These methods used must comply with the simplicity, reliability, easily reproducible and have sufficient sensitivity and very high specificity.

In general, the practice of health examinations by the nature of the screenin

g is massive gynecological examinations here also includes fluoroscopy and mammography.Widely used screening in cardiology, pharmacology, oncology and medical genetics.

screening during pregnancy appears in the life of the pregnant women in the first trimester.This is a test by which all visible abnormalities of hormones during pregnancy.

screening during pregnancy is important to preventing the risk of birth defects (neural tube defect), genetic diseases (Down syndrome, Edwards syndrome).The result itself becomes known after the testing of blood from the veins and ultrasound readings.All taken into account - the individual characteristics of pregnant (indications of height, weight, bad habits, use of hormones).

first trimester screening includes a survey of the period (dates) from 11th to 13th week of pregnancy.His task is to identify the risk of possible birth crumbs with birth defects.Screening during pregnancy itself is composed of two tests - ultrasound examination, as well as the study of venous blood.

itself first ultrasound is important to determine the constitution of the crumbs and the correct positioning of the legs, handles the circulatory system of the fetus, the length of the body, of the heart.

must be remembered and reviews of screening pregnant women it is confirmed that after the first trimester is too early to draw conclusions.And if suspected genetically malformations, it is mandatory to conduct additional research.Screening during pregnancy in the first trimester does not favor mandatory method of research for women, but if the doctor insists you should get tested, because at the screening during pregnancy refer women at high risk of pathologies.This category give birth after 35 years, as well as anyone in the family, there are patients at a genetic level, or women having abortions in the past.blood sampling during pregnancy photos

During the first trimester to analyze b-hCG (free b-subunit of human chorionic gonadotropin) and PAPP-A analysis (plasma protein).

During the second screening period (time from 16 to 18 per week) analysis is done on the three hormones - b-hCG, AFP and free estriol, but sometimes added a fourth component - inhibin A.

clarify what kind of hormonesand what effect they have on pregnancy.

hCG determined in maternal serum and is one of the important hormones during pregnancy.Screening during pregnancy determines the level of hCG, and if he dropped - evidence of placental pathology.When elevated levels of the hormone occurs chromosomal abnormalities of the fetus, indicating that harboring two or more kids.

test PAPP-A in pregnancy - is determining the amount of protein in the blood produced by the A (albumin), and is screening during pregnancy is able to identify the level of this protein.A significant reduction in the protein indicates chromosomal disorders, and this, in turn, suggests the possibility of Down syndrome, Edwards syndrome as well.

As for the level of estriol - a female steroid sex hormones in the blood, which is measured by screening during the second trimester of pregnancy.The placenta produces estriol during pregnancy, but if it happens that it is not enough, it alleges a violation of the development of the fetus.

alpha-fetoprotein or (AFP) is in the blood of the mother, as a specific protein produced during pregnancy.It happens that in violation of fetal development, the result will affect the level of AFP in the blood, it then falls, then rises.Increase will be evidence of the origin and development of congenital malformations and diseases, and reduction of the presence of Down syndrome.The sharp rise in the number of AFP increase will lead to fetal death.

If the results are not very rosy screening during pregnancy keep yourself in their hands and do not panic.You must still receive additional consultation at the genetics doctor.

screening during pregnancy often indicates the presence of problems and most likely it is connected with the appointment of hormonal drugs, as well as late delivery of analyzes
