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 .
This may also be called standard range. In contrast, optimal (health) range or therapeutic target is a reference range or limit that is based on concentrations or levels that are associated with optimal health or minimal risk of related complications and diseases. For most substances presented, the optimal levels are the ones normally found in ...
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 ...

What is a normal d-dimer range and units? [ edit ] A normal d-dimer range is between 0 and 200 in patients with VTE this level may reach 3000 — Preceding unsigned comment added by 92.22.2.188 ( talk ) 17:05, 4 July 2016 (UTC) [ reply ]
In people with a low or moderate suspicion of PE, a normal D-dimer level (shown in a blood test) is enough to exclude the possibility of thrombotic PE, with a three-month risk of thromboembolic events being 0.14%. [51] D-dimer is highly sensitive but not specific (specificity around 50%).
The normal range for a healthy person not using warfarin is 0.8–1.2, and for people on warfarin therapy an INR of 2.0–3.0 is usually targeted, although the target INR may be higher in particular situations, such as for those with a mechanical heart valve. If the INR is outside the target range, a high INR indicates a higher risk of bleeding ...
