D-dimer. D-dimer is a blood test used to help detect clots in your body or those that have embolized to your lungs. Physicians use d-dimer if they think that you have a low probability of having a clot but want to rule it out. Your test was high so the physician did the appropriate testing to determine if there was a clot. This means that your lab was falsely positive and can be elevated for other reasons.

Clinical more import. There is much more importance in this kind of situation of the clinical picture for the presence of a blood clot than the value of 1 single lab value. If your other testing is negative multiple times and a doctor's examination of the leg is negative for suspicion of a clot then, 1 single abnormal lab shouldn't change anything.
