If specimen is not clear or contains blood, centrifuge and separate

The assay manufacturer, Roche, notes that N-acetylcysteine, when
administered in high concentrations (such as for treatment of
acetaminophen overdose), can interfere with their assay for Lactate
(Lactic Acid), leading to falsely low results.
