Test Overview
Hydrolysis of Synthetic Chromogenic Substrate, Colorimetric End point.
Providing a more complete assessment of disseminated intravascular coagulation, intravascular coagulation and fibrinolysis, or hyperfibrinolysis (primary fibrinolysis), when measured in conjunction with fibrinogen, fibrin D-dimer, fibrin degradation products, soluble fibrin monomer complex, and plasminogen; Evaluating liver disease or the effects of fibrinolytic or antifibrinolytic therapy; Diagnosing congenital alpha-2 plasmin inhibitor deficiencies (rare).
80 - 140% (adults). Normal, full-term newborn infants may have borderline low or mildly decreased levels (> or =50%) which reach adult levels within 5-7 days postnatal. Healthy, premature infants (30-36 weeks gestation) may have
mildly decreased levels which reach adult levels in < or =90 days postnatal.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Specimen Requirements
Collect specimen in blue top (citrate) tube. Centrifuge specimen and aliquot citrate platelet-poor plasma into a plastic tube. Centrifuge plasma again and aliquot platelet-poor plasma into a plastic vials (no glass). Freeze plasma immediately at <40 degrees C. Transport frozen specimen on dry ice. Proper collection and handling of specimens is critical; see Coagulation tab of the handbook to ensure that the proper technique is used.
