What does a high D-dimer mean?

A positive D-dimer result may indicate the presence of an abnormally high level of fibrin degradation products. It indicates that there may be significant blood clot (thrombus) formation and breakdown in the body, but it does not tell the location or cause.

What is a dimer in medical terms?

A D-dimer test looks for D-dimer in blood. D-dimer is a protein fragment (small piece) that’s made when a blood clot dissolves in your body. Blood clotting is an important process that prevents you from losing too much blood when you are injured. Normally, your body will dissolve the clot once your injury has healed.

What causes a raised D-dimer?

An elevated D-dimer may be due to a VTE or DIC but it may also be due to a recent surgery, or trauma, infection, liver or kidney disease, cancers, in normal pregnancy but also some diseases of pregnancy such as eclampsia.

Does D-dimer go down?

One of those leftovers is called D-dimer. It’s part of a protein. Normally, with a little time, it goes away. But you can get high levels of D-dimer in your blood if you have a major clot like with deep vein thrombosis (DVT).

IS 150 D-dimer normal?

The normal range for D-Dimer is 208 to 318ng/ml. D-dimer measurement is an important diagnostic strategy of pulmonary thromboembolism (PTE) step, but its clinical usefulness is limited in elderly patients.

IS 100 D-dimer normal?

A normal D-dimer result of 500 ng/mL or less fibrinogen equivalent units (FEU) on the IL D-Dimer HS500 kit has a negative predictive value of approximately 100% (range 97%-100%) and is FDA approved for the exclusion of acute pulmonary embolism (PE) and deep vein thrombosis (DVT) when there is low or moderate pretest …

What dimer means?

: a compound formed by the union of two radicals or two molecules of a simpler compound specifically : a polymer formed from two molecules of a monomer.

What is a normal D dimer?

The normal range for D-dimer is approximately 0.5 mg/l of blood or 500 mg/ml of blood.

What does D dimer means?

D-dimer (or D dimer) is a fibrin degradation product (or 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. D-dimer concentration may be determined by a blood test to help diagnose thrombosis.

What does high D dimer levels mean?

A high D-dimer means that he has had some inflammation or breakdown of blood clots. In terms of whether this is significant, then his doctor will look at his clinical symptoms, not just the blood tests.

Is elevated D dimer life threatening?

Acute Aortic dissection is a serious and life-threatening condition with high mortality, early diagnosis is essential for survival. Elevated D-dimer, although not specific for AAD is a highly sensitive marker of the condition.

What does a high D-dimer mean? A positive D-dimer result may indicate the presence of an abnormally high level of fibrin degradation products. It indicates that there may be significant blood clot (thrombus) formation and breakdown in the body, but it does not tell the location or cause. What is a dimer in medical terms?…
