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
