[Factors influencing ethanol determination in urine using the TDx system]

The quantification of ethanol in urine samples and the susceptibility to trouble by Abbott Radiative Energy Attenuation (REA) was evaluated and compared with results by gas-chromatography (GC) and by ADH-technique. REA technique shows good reproducibility and specificity, but concerning accuracy Abbott's REA gives always lower results comparing those obtained by GC and ADH.
