Clinical laboratory investigation of a patient with an extremely high D-dimer level: A case report

Figure 1 Correlation between D-dimer values and the dilution ratio and the general view of latex agglutination assay. A: Correlation between D-dimer values and the manual dilution ratio in the patient’s (red, solid line) and parallel sample (black, dotted line); B: The latex agglutination assay uses latex beads coated with D-dimer specific antibodies. In the presence of D-dimers, latex beads, and heterophilic antibodies, agglutination is detected by turbidity.
