D-Dimer is a protein fragment produced when a blood clot dissolves in the body. Under normal conditions, D-Dimer levels are very low or undetectable. Elevated D-Dimer levels indicate that significant blood clot formation and breakdown is occurring, which may suggest deep vein thrombosis (DVT), pulmonary embolism (PE), or disseminated intravascular coagulation (DIC). D-Dimer can also be elevated in other conditions, including recent surgery, infection, liver disease, pregnancy, cancer, and systemic inflammation. While a normal D-Dimer result is useful for ruling out active clotting, elevated results typically require further investigation with imaging or additional coagulation studies. Diagnostic Blood Test: D-Dimer (Quantitative)
