Prenatal cytogenetic diagnosis: results obtained in the specialized laboratory of Clínica Universitaria Colombia from 2013 to 2019.

Objective: Prenatal cytogenetic evaluation is a key tool for identifying alterations in pregnant women with high risk for fetal chromosomal abnormalities (CA). In Colombia, there are not large-scale reports about the prevalence and pattern of CA in prenatal cytogenetic analysis.

Method: A descriptive study was performed from registers of prenatal cytogenetic analysis on amniotic fluid (AF), chorionic villus biopsy (CVS), and fetal blood (FB) samples sent to the specialized laboratory of the Clínica Universitaria Colombia between 2013 and 2019.
