amniotic fluid test - amnio

amniocentesis, is, f. – [amnion "membrane around a fetus," + centesis "surgical puncture involving a puncture,"]

amniocentesis –  transabdominal impaction of the amniotic cavity through the abdominal wall under ultrasound guidance. In layman's terms, it is a collection of amniotic fluid, intended for inspection. In amniocentesis, 10-30 ml of amniotic fluid is collected for chemical analysis, culture of amniotic cells (peeled from the fetal skin) for cytogenetic and biochemical examination (AFP, acetylcholinesterase). Chromosome analysis makes it possible to identify many hereditary ?73 conditioned syndromes, as well as to determine the sex in a family in which X-linked recessive inherited diseases are present. It is performed between 12 and 16 weeks of gestation.

Before the 15th week, this is the so-called early aniocentesis. It is especially recommended for women over 35 years of age. Fetal mortality in amniocentesis is about 1% (infection and bleeding in the mother, impaction and miscarriage in the fetus).

In justified cases, or at the request of the pregnant woman, transabdominal amniocentesis can be performed in the 15th-16th week and a sample of amniotic fluid and, in case of genetic risk in the 1st trimester (8th-10th week), a sample of chorionic villi can be taken (however, there is a risk for further fetal development and haematoma).
