HelpTest Code MATGNSO MaterniT Genome
Useful For
As early as ten weeks gestation, this test can identify common whole chromosome abnormalities, as well as, extra or missing parts of chromosomes that can cause genetic conditions difficult to diagnose at birth.
Detects up to 25% more clinically relevant chromosomal information than other leading NIPTs. Provides karyotype-level insight, information about deletions or duplications of chromosome material 7 Mb or larger, as well as analysis of seven clinically relevant microdeletion regions less than 7 Mb in size.
