Term Description

Trisomy 18 (T18) ordinal risk (high/low) 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 trisomy 13, 18 and 21 in women with singleton pregnancies of at least 10 weeks gestational age.

Change Reason
The system of 'Ser/Plas.maternal^fetus' was changed to 'Plas.cfDNA' (cfDNA from plasma, which includes both maternal and fetal DNA) to more precisely identify what is being measured.; Added "Fetal" to Component to clarify that the result is about the fetus.
