Performance of four homogeneous direct methods for LDL-cholesterol.
BACKGROUND Homogeneous LDL-cholesterol methods from Genzyme, Reference Diagnostics, Roche, and Sigma were evaluated for precision, accuracy, and specificity for LDL in the presence of abnormal lipoproteins. METHODS Each homogeneous method was performed by a Roche/Hitachi 911 according to the vendors' instructions, and the results were compared with the beta-quantification reference method. We...

able amounts of radiolabeled dextran in the plasma protein fraction [15]. Consequently, we do not think this mechanism plays a substantial role in producing the lower than expected dextran concentrations seen in the present study. The dextran we used had a mean molecular mass of 70 000 Da. Thus, some quantity of lower-molecular-mass dextran could have leaked out of the vascular space and distri...
متن کاملMethods for measurement of LDL-cholesterol: a critical assessment of direct measurement by homogeneous assays versus calculation.
BACKGROUND Because LDL-cholesterol (LDL-C) is a modifiable risk for coronary heart disease, its routine measurement is recommended in the evaluation and management of hypercholesterolemia. We critically examine here the new homogeneous assays for direct determination of LDL-C. APPROACH This review relies on published studies and data of the authors using research and routine methods for LDL-C...

exposure to artificial UV light (such as visits in the solarium). The presence of fading in single hairs of the strand or its ends should also be noted. Because of the rapid decrease in cannabinoid constituents in hair exposed to UV radiation, the result from a particular sample might be rather of a qualitative nature, and a negative finding may not conclusively indicate that there was no canna...
