Amniocentesis is a medical procedure used primarily in the prenatal diagnosis of genetic conditions. [1] It has other uses such as in the assessment of infection and fetal lung maturity. [ 2 ] Prenatal diagnostic testing, which includes amniocentesis, is necessary to conclusively diagnose the majority of genetic disorders, with amniocentesis ...
Both the patient's and the fetus' vital signs are monitored immediately following the procedure in order to ensure stability in the fetus. Usually, the patients will be monitored for about an hour following the procedure. During this time, the patient will receive education surrounding recommendations for home care post-procedure.
Amniotic fluid is removed from the mother by an amniocentesis procedure, where a long needle is inserted through the abdomen into the amniotic sac, using ultrasound guidance such that the fetus is not harmed. Amniocentesis is a low risk procedure, with risk of pregnancy loss between 1 in 1,500 – 1 in 700 procedures.
Prenatal diagnosis focuses on pursuing additional detailed information once a particular problem has been found, and can sometimes be more invasive. The most common screening procedures are routine ultrasounds, blood tests, and blood pressure measurement. Common diagnosis procedures include amniocentesis and chorionic villus sampling.
The amniotic sac, also called the bag of waters [1] [2] or the membranes, [3] is the sac in which the embryo and later fetus develops in amniotes.It is a thin but tough transparent pair of membranes that hold a developing embryo (and later fetus) until shortly before birth.

The majority of stem cells present in the amniotic fluid share many characteristics, which suggests they may have a common origin. [1]In 2007, it was confirmed that the amniotic fluid contains a heterogeneous mixture of multipotent cells after it was demonstrated that they were able to differentiate into cells from all three germ layers but they could not form teratomas following implantation ...
Amniotic stem cells are collected from amniotic fluid extracted during a genetic amniocentesis, a prenatal diagnosis procedure typically performed during the 2nd trimester of pregnancy. For the purpose of stem cell preservation, a small amount of the fluid withdrawn for genetic analysis is saved in a collection container for transport to a ...
