Despite efforts to encourage uniform reporting within methods, one can still see that a bimodal distribution is present in the CG1-B specimen (slightly elevated) in methods 2, 3, and 4, while specimen CG1-C (moderately elevated) demonstrates a bimodal pattern in all 4 methods.
For CG1-C 2007 mailing, all methods shown on the left side of the figure demonstrate bimodal distribution of the data (1: Biosite Triage [Alere San Diego, San Diego, California]; 2: HemosIL D-dimer [Instrumentation Laboratory Company, Bedford, Massachusetts; 3: HemosIl D-dimer [Top; Instrumentation Laboratory Company, Bedford, Massachusetts]; 4: bioMerieux VIDAS [bioMerieux, Marcy l'Etoile, France]).
