LaboratoryFetal Chromosome X and Y aneuploidy risk [Likelihood] based on Plasma cell-free DNA by Dosage of chromosome-specific cfDNA
Definition
The probability risk for sex chromosome (X & Y) aneuploidy can be determined based on dosage of chromosome specific circulating cell free (ccf) DNA in maternal plasma, the mother's current age and gestational age. The ccf DNA includes both fetal and maternal DNA. This code is based, but not limited in use to, the submitter's test, Harmony Prenatal Test, which is a non-invasive prenatal test intended to aid in the risk determination of fetal aneuploidy as well as trisomy 13, 18 and 21 in women with singleton pregnancies of at least 10 weeks gestational age.
