The Methodology
NICC® EXTENDED test works by isolating the cfDNA (including both maternal and fetal DNA) from a maternal blood sample and performing low coverage whole genome sequencing using Next Generation Sequencing technology. The unique reads of each chromosome are calculated and compared to an optimal reference control.
Data is analyzed using bioinformatics algorithms and a risk score and/or assessment is produced for the conditions tested for. For gender identification, cfDNA is followed with molecular genetic testing to analyze if Y chromosome is detected or not detected.
