LOINC code75555-3
nameFetal Trisomy 18 risk [Likelihood] based on Plasma cell-free+WBC DNA by Dosage of chromosome-specific cfDNA
descriptionThis term was developed for, but is not limited in use to, Natera's Panorama noninvasive prenatal test for fetal aneuploidies and microdeletions. It represents the risk based on a priori risk combined with the Panorama test result.

propertyLikelihood
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemWBC.DNA+Plas.cfDNA
scaleQn  =  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
methodDosage of chromosome specific cf DNA
