Description
Estimated cost for D-dimer test at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
The primary purpose of D-dimer testing is to rule out the presence of venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE). It is also used to monitor the effectiveness of anticoagulant therapy and in the diagnosis of disseminated intravascular coagulation (DIC).
Normal Range
The normal range for D-dimer is typically less than 0.5 micrograms per millileter (μg/mL) or 500 nanograms per milliliter (ng/mL), but this can vary slightly depending on the laboratory and the specific testing method used.
Low Values - Possible Causes
Low D-dimer levels are generally not a concern as they indicate no significant clotting activity. However, in rare cases, very low levels might be associated with: hypofibrinogenemia, liver disease, or certain hereditary conditions affecting coagulation factors.
High Values - Possible Causes
High D-dimer levels may be caused by: deep vein thrombosis (DVT), pulmonary embolism (PE), disseminated intravascular coagulation (DIC), recent surgery or trauma, and some cancers.
