An amniocentesis is a procedure in which a sample of amniotic fluid is aspirated using a needle that is inserted into the abdomen guided by ultrasound. [1] The sample is then tested, and can help doctors diagnose genetic disorders, birth defects, or other fetal health problems.
MacVector is a commercial sequence analysis application for Apple Macintosh computers running Mac OS X. It is intended to be used by molecular biologists to help analyze, design, research and document their experiments in the laboratory. MacVector 18.1 is a Universal Binary capable of running on Intel and Apple Silicon Macs.
Amniocentesis or chorionic villus sampling is necessary to conclusively diagnose the majority of genetic disorders, with amniocentesis being the gold-standard procedure after 15 weeks' gestation. [3] Transabdominal chorionic villus sampling is an alternative to amniocentesis if genetic diagnostic testing is to be performed in the first ...
There are three purposes of prenatal diagnosis: (1) to enable timely medical or surgical treatment of a condition before or after birth, (2) to give the parents the chance to abort a fetus with the diagnosed condition, and (3) to give parents the chance to prepare psychologically, socially, financially, and medically for a baby with a health problem or disability, or for the likelihood of a ...
Cell-free fetal DNA (cffDNA) is fetal DNA that circulates freely in the maternal blood. Maternal blood is sampled by venipuncture . Analysis of cffDNA is a method of non-invasive prenatal diagnosis frequently ordered for pregnant women of advanced age .

NGS technologies read the target DNA templates randomly. The target DNA or entire genome is broken into small pieces and then those DNA pieces are ligated to designated adapters for random reading during [56] in-parallel DNA synthesis. The read length corresponds to the actual number of continuous sequenced bases.
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.
