Many of you must be wondering what is prenatal diagnosis. Well it is the identification of disease before the baby is born. Yes with all the advancement that the world of science has made in leaps and bounds in the past few years, this kind of feat is achievable. You can figure if the baby that is yet to be born has been affected by some king of disease or genetic impairment. Prenatal diagnosis can be done in the form of simple screening done as a routine procedure for pregnant mothers or a more formal testing looking for specific defects or disease. And most pregnant women prefer to undergo these screening procedures so that their minds can be at peace.
What it entails
This kind of prenatal diagnosis or safet21 test price as you can call it mainly done looking for abnormalities such Down’s syndrome or other heamoglobinopathies like thalassemia. This type of screening has become a routine procedure only in the developed countries and is not still in place as routine practice in the developing world. One reason being the unavailability of facilities to provide these services for all mothers and the other being the cost of the tests itself.
This kind of diagnosis involves both invasive and non-invasive procedures. The non-invasive procedures being the ultrasound scan and the reliable genetic testing which is done by drawing a sample of the mother’s blood and testing it for any fetal abnormalities because the mother’s blood also contains fetal DNA. The ultra sound enables us to directly visualize the fetus and detect abnormalities such as neural tube defects, gastroschisis, cystic adenomatid malformation of the lung and twin to twin transfusion syndrome in the case of a twin pregnancy. Examination of maternal blood for fetal DNA is helpful in detecting genetic disorders called x linked genetic disorders which are an abnormality of the chromosome that makes up an individual’s DNA.
The development of such procedures has proved to be an excellent step ahead in the world of science and medicine. Because it not only allows the doctors to detect any abnormalities very early on and maybe try and prevent further disease progression if possible, but it also helps the parents be better prepared for what they are about to face. Because seeing the abnormality once the baby is born is a bigger shock then knowing it beforehand and being prepared for it? And in some countries parents are given the option of going for an abortion if such an abnormality is detected at the beginning of the pregnancy.
