NADH cytochrome C reductase/Citrate synthase [Enzymatic activity ratio] in Tissue   74590-1

LOINC Code


LOINC code74590-1
nameNADH cytochrome C reductase/Citrate synthase [Enzymatic activity ratio] in Tissue
descriptionAssesses the ratio between the activity of Complex I + III and citrate synthase. This ratio gives an idea of the amount of activity of complex I + III relative to the amount of mitochondria. The submitter' slab measure Complex I+III activity as rotenone-sensitive NADH cytochrome c reductase activity.
statusACTIVE

Fully-Specified Name

componentNADH cytochrome C reductase/Citrate synthase
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.
systemTiss  =  Tissue, unspecified
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
