D-dimer (or D dimer) is a dimer that is a fibrin degradation product (FDP), a small protein fragment present in the blood after a blood clot is degraded by fibrinolysis. It is so named because it contains two D fragments of the fibrin protein joined by a cross-link , hence forming a protein dimer .
However, the sensitivity and specificity of these methods is limited because elevation of these biomarkers can also occur induced in other clinical conditions. The classical coagulation tests such as PT ( prothrombin time ), aPTT ( activated partial thromboplastin time ) or thrombin time are not very sensitive for hyperfibrinolysis, and ...
Principles of D-dimer testing. Fibrin degradation products (FDPs), also known as fibrin split products, are components of the blood produced by clot degeneration. [1] Clotting, also called coagulation, at the wound site produces a mass of fibrin threads called a net that remains in place until the cut is healed. As a cut heals, the clotting ...

This is a test that is primarily used as a confirmatory test, meaning it confirms a previous analysis showing the presence or suspected presence of a pulmonary embolism. [36] According to a cross-sectional study, CUS tests have a sensitivity of 41% and specificity of 96%. [36]
In medical diagnosis, test sensitivity is the ability of a test to correctly identify those with the disease (true positive rate), whereas test specificity is the ability of the test to correctly identify those without the disease (true negative rate). If 100 patients known to have a disease were tested, and 43 test positive, then the test has ...
The testing kit, which costs approximately $150, involves swabbing the cheek and mailing the sample back to a laboratory company to see if the gene mutations are present.. Results typically come ...
