title: Prenatal cytogenetic analysis of the fetus.
abstract: A number of different cell sources can be used for prenatal cytogenetic analysis, the most common being chorionic villi and amniotic fluid. Analysis can be done at any time between 9 weeks' gestation and term. Depending on the cell source and type of analysis required, the laboratory will take anywhere from 24 hours to 2 weeks to complete the study.
