Abstract
Summary:

This experiment involves a spectrophotometric measurement using Roche Cobas Clinical Chemistry Analyzer. Serum levels of total cholesterol reflect cholesterol metabolism and are associated with cardiovascular disease.

Notes:

√ Try to use freshly prepared serum and plasma samples for this assay.

√ No dilution or treatment of the sample is required, but plasma samples should be centrifuged to remove any fibrin/fibrinogen clumps.

√ Samples should be stored at 2-8°C for 24 hours prior to analysis. For longer periods, store samples at -70°C, and avoid repeated freeze/thaw cycles.

√ A 50 l dead volume is required in addition to sample volume for multi-protein analysis (typically 1-5 l).
Perform daily quality control assessment of instrumentation before analysis.
Load each sample into a specialized micro-sample cup for the clinical chemistry analyzer.
Select Cholesterol (Total) test on display and run the analysis.
Collect and analyze the data.
