My wife recently had discomfort on her left side, beneath her left arm pit. She saw her doctor and he had a d dimer blood test run. Normal range is under 250 we understand. Her result was 5036. Our doctor ordered a ct scan, which was performed a few days later. The results were negative. Our doctor then said to let him know if the pain didn t go away,or got worse. There was no additional information provided as to the cause of the elevated d dimer number. My wife has RA, which we understand might effect the d dimer number, but no one has told us anything additional to calm our fears which are born out of our ignorance of the situation. Can you offer any possible explanations in this matter?
