Which is NOT a reported analytical concern for lipid measurements?

Lipid measurements are highly sensitive to how a sample is handled before analysis. Delaying processing gives time for lipolytic enzymes in the blood to act, releasing fatty acids and glycerol and often causing a false increase in measured lipid levels, especially triglycerides. If the sample isn’t kept iced, ongoing enzymatic and chemical changes at room temperature can lead to a lower result, a false decrease in lipids. Hemolysis can interfere with the assay—either through optical interference or release of intracellular components—often producing a higher reading, a false increase. Heat exposure isn’t typically cited as a reported analytical concern for lipid measurements, so it’s not considered a factor that biases these results in standard practice.
