Trisomy is a genetic anomaly that is characterized by the presence of an extra chromosome in the cells of a fetus. The trisomy most frequently encountered in humans is trisomy 21, followed by trisomy’s 18 and 13.
The purpose of the NIPT test is to analyze fetal DNA circulating in the maternal blood by means of high throughput sequencing of DNA via NGS (Next Generation Sequencing) technology coupled with a powerful bioinformatics analysis. This method allows a detection rate of trisomy’s higher than 99% without risk for the fetus.
Fast, reliable and safe, the NIPT can detect trisomy’s 13, 18 and 21 with a simple sample of maternal blood and avoids the risk of miscarriage associated with invasive sampling.
