Amniocentesis should be performed in mothers 35 years of age and older and in cases where there is a risk in triple test.
From the beginning of pregnancy to the first embrace of the baby, every parent is concerned about the health of their baby. Today, the prenatal diagnostic methods applied to babies have the chance to protect from danger. One of these methods is amniocentesis. Amniocentesis, which means that the baby is taken from the fluid in the mother's womb, is generally used for the definitive diagnosis in mothers aged 35 and older and in cases where a triple test is detected.
What is amniocentesis?
Amniocentesis, which is one of the most commonly used diagnostic methods, means taking a sample of the amniotic fluid that the baby is swimming in the womb with the help of a thin needle. Acıbadem Hospital Gynecology and Obstetrics Specialist Op. Dr. Contact Mustafa directly He explains the method: ulaşıl In this method, the uterus and the amniotic fluid that the baby swims in are reached with a needle entered through the abdominal skin of the expectant mother. A small amount of amniotic fluid is withdrawn with the help of an injector and sent to the laboratory. Diagnostic amniocentesis is usually performed during 15th and 17th gestational weeks. It is not appropriate to apply it in the future weeks of pregnancy ... Laboratory results are only 2 - 3 weeks. Although chromosomal abnormality is detected in the baby after 24th gestational week, amniocentesis is not possible at the latest 20-21 because it is not possible to terminate the pregnancy. It is necessary to perform a week. ”
Amniocentesis is used to determine if the baby has chromosomal abnormalities. The diagnosis of down syndrome, one of the most common anomalies in the community, is made by amniocentesis. With this application, some metabolic diseases can be diagnosed except chromosomal anomaly diagnosis, further examination can be performed for neural tube defects and it can be determined whether the lungs mature when the baby should be born prematurely due to a disease belonging to the mother candidate.
