LOINC Code


LOINC code30035-0
nameDeprecated Homocystine [Moles/volume] in Serum or Plasma --fasting
statusDEPRECATED
status reasonErroneous - Our understanding is there is no assay that measures homocystine and homocysteine separately. There is precedence in the literature and reference labs for homocyst(e)ine, so this LOINC term is deprecated and mapped to its corresponding homocyst(e)ine term.

Fully-Specified Name

componentHomocystine^post CFst
propertySCnc  =  Substance Concentration
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.
systemSer/Plas
    Ser  =  Serum
    Plas  =  Plasma
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
