Device Description
The Dade Behring Dimension® Automated LDL Cholesterol Flex® reagent cartridge method is an in vitro diagnostic test that consists of prepackaged reagents in a flexible plastic cartridge for use on the Dimension® clinical chemistry system. The Dimension® Automated LDL Cholesterol Flex® reagent cartridge assay is a homogeneous method for directly measuring low-density lipoprotein cholesterol in human serum or plasma without the need for off-line pretreatment or centrifugation steps.
The method is in a two reagent format and depends on the properties of detergent 1 which solubilizes only non- LDL particles. The cholesterol released is consumed by cholesterol esterase and cholesterol oxidase in a non-color forming reaction. Detergent 2 solubilizes the remaining LDL particles. The soluble LDL-C is then oxidized by the action of cholesterol esterase and cholesterol oxidase forming cholestenone and hydrogen peroxide (H2O2). The enzymatic action of peroxidase on H2O2 produces color in the presence of (11507).

Image /page/1/Figure/1 description: This image shows a series of chemical reactions. In the first reaction, nonsoluble LDL-C, VLDL-C, HDL-C, and Chylomicrons are converted to soluble Non-LDL-C, (VLDL-C, HDL-C, Chylomicrons) using Detergent 1. Soluble Non-LDL-C is converted to a non-color forming product using Cholesterol esterase and Cholesterol oxidase. In another reaction, nonsoluble LDL-C is converted to soluble LDL-C using Detergent 2, and soluble LDL-C + O2 is converted to Cholestenone + H2O2 using Cholesterol esterase and Cholesterol oxidase. Finally, H2O2 + DSBmT + 4-AA is converted to a color development product using Peroxidase.
Intended Use: The Dimension® Automated LDL Cholesterol Flex® reagent cartridge method is an in vitro diagnostic test intended for the quantitative determination of lowdensity lipoprotein cholesterol in human serum and plasma.
