| name | Fetal Trisomy 18 risk [Likelihood] based on Plasma cell-free DNA by Dosage of chromosome-specific cfDNA | ||
| description | The probability risk for trisomy 18 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 sex chromosome aneuploidy as well as trisomy 13, 18 and 21 in women with singleton pregnancies of at least 10 weeks gestational age. | ||

| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Plas.cfDNA | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||

| 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. | ||
