Fetal Chromosome 21 trisomy [Presence] based on Plasma cell-free DNA by Sequencing   77011-5

LOINC Code


LOINC code77011-5
nameFetal Chromosome 21 trisomy [Presence] based on Plasma cell-free DNA by Sequencing
descriptionThis term was created for, but is not limited in use to, Sequenom Laboratories' MaterniT21 PLUS trisomy 21 test, which analyzes circulating cell-free DNA extracted from maternal plasma for chromosome 21 aneuploidy using whole genome sequencing. MaterniT21 PLUS is indicated for use in pregnant women with increased risk for fetal chromosomal aneuploidy.
statusACTIVE

Fully-Specified Name

componentFetal chromosome 21 trisomy
propertyPrThr  =  Present or threshold:  The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold.
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.
systemPlas.cfDNA
scaleOrd  =  Ordinal:  Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive.
methodSequencing

Associated Observations

LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations.

Member of these Panels

77018-0Noninvasive prenatal fetal 13 and 18 and 21 aneuploidy panel - Plasma cell-free DNA by Sequencing

History/Usage

first released
last updated2.73
last change typeMIN  - change to field other than name
change reasonThe PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; Added "Fetal" to Component to clarify that the result is about the fetus.
