[Evaluation of novel assays for the detection of crosslinked fibrin degradation products in whole blood by the agglutination of the red blood cells].
We evaluated the clinical significance of two novel assays for the detection of crosslinked fibrin degradation products (XDP) in whole blood using the agglutination of the red blood cells (SimpliRED D dimer and SimpliRED D dimer-500, AGEN, Australia). XDP made serially by plasmin in vitro, were detected by the SimpliRED D dimer assay, but fibrinogen degradation products showed weak reactivity. Ten of the fifty four clinical samples collected with EDTA-2K, changed to positive on these assays after overnight incubation at 4 degrees C. Anemia and hemolytic samples had no effect on the assay results. The results obtained by the SimpliRED D dimer were negative for the normal subjects (n = 50) without exception. In our study, 81% and 95% of the patients, who showed abnormal levels of XDP in plasma and E fragments in serum respectively, were positive on the SimpliRED D dimer assay. The assay was as sensitive as the Rapidia-D dimer assay. In conclusion, the SimpliRED D dimer assay was clinically useful as a screening assay for the diagnosis of hypercoagulable and fibrinolytic states, since it could be performed simply and quickly.
