A member asked:
Why would i have repeated high d-dimer tests but have doctors unable to find any signs of clots?

Positive not useful: A negative d-dimer test is very useful--because it practically tells you no clot. A positive test is not very useful because quite a few conditions cause positive d-dimer test: liver disease, high rheumatoid factor, inflammation, malignancy, trauma, pregnancy, recent surgery as well as advanced age can cause high d-dimer test.. Consult your doc for more info. Good luck.

High D-dimers: The d-dimer is an acute phase reactant. That means that anything that causes inflammation will cause the d-dimer level to be elevated, as dr. Nguyen so nicely spelled out. Since elevated d-dimer levels are so no-specific, they are often times essentially meaningless in giving specific information.
