#amniotic fluid

• Amniocentesis — An invasive prenatal diagnostic medical procedure consisting of the transabdominal puncturing of the uterine wall and the amniotic sac, under ultrasound guidance, to extract a sample of amniotic fluid. This technique allows the analysis of desquamated fetal cells in order to detect genetic or chromosomal abnormalities (such as Down syndrome) or intrauterine infections.
• Amnioscopy — An endoscopic clinical diagnostic method that allows the direct visualization of the lower pole of the ovular sac, the membranes, and the appearance of the amniotic fluid through the cervix, utilizing a conical tube equipped with a light source. This investigation is used near the end of pregnancy to detect acute fetal distress by observing fluid color changes (such as the presence of meconium).
• Amniotic — Belonging to the amnion, relating to the amnion or the gestational sac of the embryo; produced, secreted, or located inside the fetal cavity. In a clinical context, the term describes the fluidic, cellular, or structural elements that compose and support the intrauterine developmental environment of the fetus.
