A cutoff of 100 ng/mL has been determined to be the lowest detectable concentration that is distinguishable from zero. An elevated D-Dimer can be linked to patients with venous thromboembolism, including Pulmonary Embolism (PE) and Deep Venous Thrombosis (DVT). The results of the D-Dimer test should be evaluated in context with all available clinical and laboratory data.
