Comments

Assay interference (negative) may be observed for Total Cholesterol when high concentrations of N-acetylcysteine (NAC) are present.

Venipuncture immediately after or during the administration of Metamizole (Dipyrone) may lead to falsely low results for Total Cholesterol and Triglyceride. Venipuncture should be performed prior to administration of Metamizole.
