Deprecated Homocystine [Molar concentration difference] in Serum or Plasma --6 hours post dose methionine - post CFst 33061-3
LOINC Code
| LOINC code | 33061-3 | ||
|---|---|---|---|
| name | Deprecated Homocystine [Molar concentration difference] in Serum or Plasma --6 hours post dose methionine - post CFst | ||
| description | The result is the difference between the post challenge value and the fasting value | ||
| status | DEPRECATED | ||
| status reason | Erroneous - 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 | |||
| component | Homocystine^6H post dose methionine - post CFst 6H = 6 hours post challenge | ||
| property | SCncDiff = Difference in Substance Concentration | ||
| 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 | Ser/Plas Ser = Serum Plas = Plasma | ||
| 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 | ||
