Normal: The normal range for any test usually spans two standard deviations, or about 87% of normal. Thus about 6% of tests just above or just below normal are also normal. So a test result just within the upper limit of normal is quite normal, with a safety range just above or below for 6%!of the population from which the "normal" range is determined. That's a long way of saying your result is very norma

But... why do you want a d-dimer? It is not a useful test out of context, and a positive result may not mean what you think it does. Tread with caution when ordering a blood test.

Efficacy of d-dimer: That is actually a hard question to answer. There are different testing methods and some d-dimer tests are more reliable than others. If you have a low probability of having a blood clot by history and a low d-dimer, it is pretty safe to say that you don't have a blood clot. If you have a high d-dimer and a high probabilty of a blood clot by history, then your risk of a clot is high.

High d-dimer: High d-dimer results can occur because of essentially inflammatory process. Besides blood clots, high results can be due to various causes: liver disease, high rheumatoid factor, inflammation, malignancy, trauma, pregnancy, recent surgery, and advanced age, to name a few. A high d-dimner is very non-specific. A low d-dimer is very help[ful in ruling out blood clots.

Can having an elevated d dimer be dangerous?

Perhaps: The d-dimer is a fibrin degradation product (or fdp) which represents a small protein fragment in blood after a blood clot is broken down. The value can be used to test for clotting or thrombosis problems. However, a single value or a value in isolation should not be used. Elevations may suggest a clotting problem.
