[A simplified, Fully Enzymatic Cholesterol Determination: (author's transl)]

Area of Science:

• Clinical Chemistry
• Biochemical Analysis

Background:

• Conventional methods for cholesterol determination present challenges including reagent handling and potential metabolic inhibition.
• Enzymatic analysis offers a promising alternative with distinct advantages.

Purpose of the Study:

• To highlight the benefits of enzymatic cholesterol determination compared to conventional techniques.
• To establish new reference values for serum cholesterol based on enzymatic analysis.

Main Methods:

• A simplified, fully enzymatic method for cholesterol determination was employed.
• Comparison between enzymatic and conventional chemical analysis was performed.

Main Results:

• Enzymatic analysis demonstrated high analytical precision and user-friendly reagents.
• No inhibition by metabolites was observed in the enzymatic method.
• A poor correlation was found between enzymatic and chemical cholesterol measurements.

Conclusions:

• Enzymatic cholesterol determination is a precise and reliable method.
• New cholesterol reference values are necessary due to discrepancies with chemical methods.
• Recommended cholesterol levels: normal ≤200 mg/dl, borderline 200-250 mg/dl, pathological >250 mg/dl.
