Evaluating patients with ligneous conjunctivitis (strong association with homozygous plasminogen deficiency)
Evaluating fibrinolysis, in combination with other components of the fibrinolytic system (fibrinogen, tissue plasminogen-activator-inhibitor, and d-dimers)
1. Spin down, remove plasma, and spin plasma again. 2. Freeze specimen immediately at < or =-40 degrees C, if possible.
Additional Information: 1. Double-centrifuged specimen is critical for accurate results as platelet contamination may cause spurious results. 2. Each coagulation assay requested should have its own vial.
