I [Geo] received this 2-1-24 email from a correspondent who had expressed concern for his isolated elevated D-dimer. This is an issue we’ve addressed in the past that prompted me to prepare a summary entitled Isolated Chronically Elevated D-dimer. Here’s the note:
Hello. We had email contact in 2023 and it was about a chronically elevated D-dimer, for which no cause could be found despite countless examinations. I think I was able to solve the puzzle, at least in my case. I went to the dentist and had a panoramic x-ray taken. It turned out that a wisdom tooth was extremely infected/inflamed. My D-dimer was 1.6 (reference range up to 0.5). This tooth was treated under a microscope in the root canal (because it holds a dental bridge) and was saved. A short time later my D-dimer dropped the first time since years under 1.0 to 0.7. The conclusion in my case: we wrote back then that my chronic gastritis (i.e. inflammation) was probably responsible for the increased D-dimer. It could also have been my liver hemangioma. But it looks as if even unknown (because there are no symptoms) tooth infections can be considered for increasing the D-Dimer. I wanted to share this with you because we had such nice email correspondence back then. I wish you all the best!
