Muestra de vellosidad coriónica

El corion es la porción de la membrana fetal que paulatinamente forma el lado fetal de la placenta. Éste contiene vellosidades coriónicas, que son pequeñas salientes semejantes a dedos. Estas vellosidades se cortan con tijeras o se succionan para analizarlas. Debido a que su origen es fetal, al examinar las muestras se puede obtener una estructura genética del feto. Este examen se realiza para detectar defectos congénitos a tiempo. La muestra se utiliza para estudiar el ADN, los cromosomas y las enzimas del feto. El examen puede realizarse antes de la amniocentesis, aproximadamente de 10 a 12 semanas después de la falta de un período menstrual.
