Clinical Interest
D-dimer testing is a valuable tool in the diagnosis, risk stratification, and management of thromboembolic disorders and other conditions associated with abnormal coagulation and fibrinolysis.
A negative D-dimer test result has a negative predictive value in the diagnosis of deep vein thrombosis and pulmonary embolism.
However, it is important to interpret D-dimer results in the context of the patient's clinical presentation and other diagnostic findings.

Patient Collection Note
A completely filled tube is necessary because the correct ratio of blood to citrate is critical (9:1). Mix by gentle inversion 3-4 times. Do not uncap.
