I have been having shortness of breath. Had a elevated d dimer in April and now another one. D dimer went from .74 to 1.1. They checked for blood clot in lungs and did not find anything. I had been having diarrhea every morning for months although that finally seems to be getting better I also have hashimotos and had an elevated c reactive protein and rheumatoid factor . I read that an elevated d dimer could mean cancer . How do you know if you have some kind of gastric cancer? I have had a lot of blood work and a normal stool sample. Would it show up?
Hi, D-dimer estimation is done for clotting associated disease like pulmonary embolism, DVT etc. There are scoring system to assess the results. Anyway, positive rheumatoid factor may give false positive d-dimer result. This value has got no relation with diagnosis of gastric cancer. If you have any clinical feature suggestive of the same upper G-I endoscopy would be helpful. Consult your doctor.
