Two major clinical applications of D-dimer in tumor diagnosis and treatment!

D-dimer is a product of the degradation of cross-linked fibrin by plasmin, and its production requires the synergistic action of thrombin, activator IIIa, and plasmin. At present, the commonly used cutoff value for D-dimer is 500 μ g/L. Due to different detection methods, the cutoff value may vary to some extent.
