D-Dimer, Plasma
Use
The D-dimer test is useful for the diagnosis of intravascular coagulation and fibrinolysis, known as disseminated intravascular coagulation, when combined with clinical information and other laboratory tests like platelet count, clottable fibrinogen, and clotting time assays. It also helps in the exclusion of acute pulmonary embolism or deep vein thrombosis diagnosis, particularly when results are combined with clinical information, including pretest disease probability.
Special Instructions

Limitations
Lipemia can cause an overestimation of the D-dimer level, and results from lipemic specimens should be interpreted with caution. The presence of rheumatoid factor above 50 IU/mL may also lead to an overestimation. Increased D-dimer values are not specific to any disease and can be elevated due to conditions like recent surgery, bleeding, trauma, or thromboembolism, and are associated with pregnancy, malignancy, or liver disease.
