A level in this range indicates the presence of a small amount of the substance that is released when blood clots dissolve, indicating that there is likely not a blood clotting issue.

The age-adjusted D-dimer threshold was more specific (64% versus 54%) but less sensitive (93% versus 98%) than the standard threshold of 500 ng/dL; 11,999 imaging studies identified 507 pulmonary embolisms (4.2%); of these, 1,323 (10.6%) were performed with a D-dimer result below the standard threshold.
