nameAcyl CoA dehydrogenases.palmitate substrate/Acyl CoA dehydrogenases.myristate substrate [Enzymatic activity ratio] in Fibroblast
descriptionMedium- and long-chain acyl CoA dehydrogenase deficiencies can be differentiated based on the ratio of palmitate oxidation [LOINC: 78358-9] and myristate oxidation [LOINC: 78360-5] in cultured fibroblasts. Patients with medium chain acyl-CoA dehydrogenase deficiency (MCAD) typically have a high palmitate/myristate (P/M) ratio. Long-chain defects, including VLCAD and LCHAD, generally have a low P/M ratio. [PMID: 10709659]

componentAcyl CoA dehydrogenases.palmitate substrate/Acyl CoA dehydrogenases.myristate substrate
propertyCRto  =  Catalytic Ratio
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.
systemFibroblasts
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
