It is a procedure that is used to take the sample out from the amniotic fluid for testing. Amniotic fluid is the fluid that surrounds the embryo in the pregnant woman; it is a translucent, pale yellowish fluid that protects the embryo from any injury. One of its major is that it protects the embryo against any infections. Amniocentesis is a medical test or course of action in which is majorly used in prenatal diagnosis of any chromosomal malformation or anomaly and fetal infections.
It is also used in determining the gender of the baby at the very initial stage. In this process of genetic trial, a minute sample of amniotic fluid is collected which contains fetal tissues; it is sampled from the amniotic sac that surrounds the developing embryo. The fetal DNA is examined to know if there is any genetic idiosyncrasy in the fetus. The examiner that is collecting the sample for this test needs to be very accurate and precise while collecting the sample as the sample is collected via syringe with the fetus still in the stomach of the pregnant woman. The results of this test are very faultless.
The most common reason behind taking this test is to gain knowledge about the medical conditions of the fetus if there is any or to know if there is any chromosomal anomaly such as Down syndrome. Amniocentesis can know about such conditions in the womb only, such prenatal examinations can be very beneficial to the expectant guardian as one can evaluate the fetal health status of the embryo, and then the feasibility of the treatment can also be checked after observing the test results of this DNA test.
