The study found that daily serum biomarker D-dimer levels (increasing or decreasing trends) can predict whether a COVID-19 patient's oxygen requirements will be worsening or improving compared to ...

However, 25.3% of patients had D-dimer levels higher than 500 ng/mL up to 4 months after diagnosis, with a median D-dimer level of 744 ng/mL among this group.

Abnormal test results may identify patients who could benefit from a longer course of the therapy. (Palareti G, et al. <i>N Engl J Med</i> 2006; 355:1780-1789.) ...

Compared with the 70 patients whose D-dimer levels were ≥750 ng/mL, the 209 patients with levels of <250 ng/mL had a significantly lower relative risk for VTE recurrence (RR, 0.3), even after ...

When the new cut-off value was used, the relative number of patients in whom the D-dimer test was negative increased considerably (20.1%, 11.2% and 18.2% in each data set), with only a modest ...

Plasma levels of D-dimer are elevated in cancer patients. Activation of the extrinsic coagulation system and the fibrinolytic cascade within a tumour is thought to be related with growth, invasion ...

Elevated levels of factor VIII, D-dimer, or both at diagnosis were highly predictive of a poor outcome (odds ratio, 6.1; P=0.008), as was the persistence of at least one laboratory abnormality at ...
