WebResults: A total of 759 extremely elevated D-dimer results were identified. After exclusion of 120 duplicate cases, 53 patients undergoing cardiopulmonary resuscitation, and 5 cases without diagnostic information, 581 cases were analysed. Their D-dimer ranged between 5030 and 239,000 μg/l, with a mean of 17,598 μg/l (SD 22,972 μg/l). WebA higher than normal D-dimer level might mean you have had a significant blood clot. However, the test does not tell where the clot was or what caused it. Other health problems can also cause the D-dimer level to go up. Therefore, the D-dimer test is not the only test used to diagnose a disease or condition.
