Results: 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). Altogether, 89% of these patients had a diagnosis of VTE, sepsis and/or cancer. The prevalence was highest for pulmonary embolism (183 patients; 32%), followed by cancer (168 patients; 29%), sepsis (142 patients; 24%), trauma/surgery (142 patients; 24%), and deep vein thrombosis (73 patients; 13%).
Never ignore extremely elevated D-dimer levels: they are specific for serious illness...

The question is, how elevated did that Canadian doctor say the levels were in the 62% of patients?
He threw out a range but I didn’t remember, and I don’t want to relisten to the whole thing this time of night.
