Did you know that ultrasound examinations, which are also based on pregnancy tests, were really inspired by military technology? Or, before modern pregnancy diagnostic methods, were you using a damaging fetus?

Where did prenatal diagnostics begin and develop? What are the latest test methods?

The bloody exams are back and forth

Ultrasound history is a It dates back to the end of the 18th century: This is when we first noticed that bats were hearing. Subsequently, the scientists began to experiment with light, and in 1826 the sound underwater was investigated. After the Titanic catastrophe, we discovered a hydrophone capable of receiving and transmitting low-frequency sound waves, such as being able to detect a threatening iceberg. The technique was also used to identify the position of submarines under World War II. Ian Donald applied first in medicine. First, abdominal tumors, then From 1957 onwards, she observed fetal abnormalities ultrasound examination with the aid of. For the early detection of pregnancy, he first used the method in 1963, unlike the contrary, it has not had any adverse effects to the developing fetus. Because of his work, Ian Donald is considered to be the father of ultrasound in obstetrics. Since then, ultrasound technology has evolved rapidly: we are now able to the finest details of fetal development too. "Pregnancy ultrasound plays a key role in prenatal diagnosis - thanks to the latest 3D and 4D ultrasound techniques, it can not only monitor the development of the fetus but also monitor the development of the fetus" Dr. Csaba Papp, associate professor, clinical geneticist, member of the PrenaTest Professional Advisory Board. He added that besides an anatomical examination of the fetus, it is an important part of genetic disorders of the fetus - The most common Down course is the diagnosis and diagnosis of the edge. " higher risk pregnancies. Ultrasound imaging fetal thymus-thickeningin parallel, we also determine the exact age of the pregnancy and the distance of the fetal head. If the risk is 1: 250 or higher, the screening test is considered positive, and further diagnostic safety tests are recommended for the pregnant mother. PrenaTest, which has the advantage of having a biopsy and amniotic fluid examination, without risk of miscarriage it is possible to detect with great certainty any fetal chromosome aberration that may persist, "explains the expert, who also points out that the most recent test available in our country with maternal blood we can test the genetic status of the fetus. "The latest version of the test is qPCR technology with the help of screening for fetal Down syndrome in maternal blood during early pregnancy. Fetal DNA testing with new technology recognizes the presence of a chromosome aberration with the same high level of certainty as the previous sequencing technique, but is significantly faster and cheaper. With the help of a significantly broader range of patients, modern genetic diagnostics are expected to be available, "explains Dr. Csaba Papp, who also recommends that genetic counseling be given to those who are already pregnant before they become pregnant.
