Pregnant Women and Amniocentesis Test

Because of the new era of medical advances, parents are expected to have many opportunities to monitor and test the health of pregnant women and babies. The parent's program to diagnose fetal genetic diseases provides families valuable knowledge about the genetic makeup of children. Currently, many genetic tests are available and are recommended for pregnant women with different invasiveness, risk, accuracy, cost, and suitability for specific indications. Today, the mature technique to obtain genetic information about the fetus is amniocentesis.

Genetic testing and genetic counseling are recommended for families with haemophilia. Prenatal testing such as amniocentesis can be used for pregnant women who may be carriers of this disease. According to CDC data, median age of mild haemophilia patients is 36 months, patients with moderate haemophilia 8 months, patients with severe haemophilia 1 month. About two-thirds of cases, there is a family history of haemophilia. Diagnosis of haemophilia is done by special blood test, most babies can be inspected immediately after birth. Prenatal genetic testing to diagnose prenatal haemophilia

A 46-year-old pregnant woman visited a clinic in the Royal Melbourne Hospital in Australia and heard the results of amniocentesis in order to screen chromosomal abnormalities in infants. Babies are very good - but follow-up testing reveals amazing things about mothers. Her body is composed of two human cells, probably from twins that are combined in the mother's womb. There are more. A group of cells has two X chromosomes, usually one female and another has X and Y. Most of her body is a male with chromosome 1. James said: "For those who have just started amniocentesis, this is the material of science fiction novels."

Analysis of the fetal chromosomal material obtained during amniocentesis or chorionic villus sampling is necessary to prove the existence of extra copies of chromosome 18. Amniocentesis is usually done at 15 to 18 weeks gestation, prenatal diagnosis of 18 trisomy. In the most commonly used test in this procedure, a thin needle is inserted through the abdominal wall and a small sample of amniotic fluid is taken. Chorionic villus sampling is another test that enables the examination of fetal genetic material. Because it is done in the early pregnancy (10 to 12 weeks after the last menstruation), there is an advantage that early diagnosis is possible. The method includes collecting a sample of chorionic villous cells from the placenta by inserting a needle through the catheter in the vagina via the abdominal wall or needle.
