Spectrum SNP array is the most comprehensive testing technology available. SNP array testing is performed using an embryo biopsy sample with parental blood/cheek swab samples. Natera’s exclusive Parental Support bioinformatics technology is the only technology that can confirm an embryo matches parental samples. Spectrum SNP arrays with Parental Support is highly accurate across all chromosomes, including the sex chromosomes, and it provides more information than other testing technologies (e.g., haploidy/triploidy, uniparental disomy, and parental origin of aneuploidies).* *Reference: Johnson, DS et al. 2010 Hum Repo 25(4): 1066-1075.
