What is considered a high D-dimer level?
A normal D-dimer is considered less than 0.50. A positive D-dimer is 0.50 or greater.
Should I worry about a high D-dimer?
An elevated D-dimer level is not normal. It’s usually found after a clot has formed and is in the process of breaking down. If you are having significant formation and breakdown of blood clot in your body, your D-dimer may be elevated. A negative D-dimer test means that a blood clot is highly unlikely.
What happens if my D-dimer is high?
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 does the D-dimer test results mean?
What do the results mean? If your results show low or normal D-dimer levels in the blood, it means you probably don’t have a clotting disorder. If your results show higher than normal levels of D-dimer, it may mean you have a clotting disorder. But it cannot show where the clot is located or what type of clotting disorder you have.
What does it mean to have low D-dimer in blood?
If your results show low or normal D-dimer levels in the blood, it means you probably don’t have a clotting disorder. If your results show higher than normal levels of D-dimer, it may mean you have a clotting disorder. But it cannot show where the clot is located or what type of clotting disorder you have.
Can a pregnant woman get a D-dimer blood test?
Women who are pregnant will commonly test positive, but should have results return back to normal after childbirth. The specificity of the D-dimer blood test is rather low. It can indicate the presence of a potential blood clot, but it cannot lead to a diagnosis of where that clot may be.
How is D-dimer produced in the body?
D-Dimer is one of the protein fragments produced when a blood clot gets dissolved in the body. It is normally undetectable or detectable at a very low level unless the body is forming and breaking down blood clots. Then, its level in the blood can significantly rise.
