EVALUATION OF THE ABBOTT TDX-RADIACTIVE ENERGY ATTENUATION (REA) ETHANOL ASSAY IN A STUDY OF 1105 FORENSIC WHOLE BLOOD SPECIMENS

In this study, 573 blood specimens from suspected driving while intoxicated individuals (DWI blood) and 532 postmortem blood specimens (PM blood) were analyzed by the REA Method and a headspace gas chromatographic method (GC). Negative specimens (less than 10 mg/dL by GC) and positive specimens (greater than or equal to 10 mg/dL by GC) in each category were analyzed. Linear regression analysis comparing the REA values with the GC values was performed for each type of blood specimen. The equation obtained for DWI blood specimens was REA=0.943 GC plus 1.54; the equation for PM blood specimens was REA = 0.980 GC plus 2.76. The correlation coefficient for each group was greater than 0.99. The data suggested that a limit of detection of 10 mg/dl could be applied for DWI blood specimens while 20 mg/dL would be recommended as the limit of detection for PM blood specimens.
