D-dimer test
The D-dimer test measures a substance in the blood that's released when a blood clot dissolves. It's commonly used to help diagnose conditions related to abnormal clotting, such as deep vein thrombosis (DVT) or pulmonary embolism (PE). A high D-dimer level may suggest the presence of a clot, but it doesn't confirm one, as other factors can also raise levels. Therefore, further tests are often needed for a definitive diagnosis. Essentially, the D-dimer test helps doctors assess the likelihood of clotting disorders in patients presenting with symptoms.

The D-dimer test is a blood test that measures the presence of a substance called D-dimer, which is released when blood clots break down in the body. Doctors use this test to help diagnose conditions related to abnormal clotting, such as deep vein thrombosis (DVT), pulmonary embolism (PE), or disseminated intravascular coagulation (DIC). A high D-dimer level may indicate the presence of these conditions, but it is not definitive; further tests are often needed to confirm a diagnosis. A normal D-dimer level can help rule out serious clotting disorders.
