HerCheck NIPT All Chromosomes is a non-invasive prenatal screening test. This method involves the analysis of cell-free fetal DNA (cffDNA) circulating in maternal blood, without any risk to the fetus, to screen for aneuploidies (extra/missing chromosomes) across all 23 pairs, not just the common trisomies (21, 18, 13). It provides comprehensive insights into fetal health, covering rare autosomal trisomies and sex chromosome abnormalities.
