Interference in specialized coagulation assays affecting the protein C pathway: Effects of marked haemolysis, hyperbilirubinaemia and lipaemia on chromogenic and clotting tests on two coagulation platforms.

Our data show that the degree of interference associated with haemolysis, lipaemia and hyperbilirubinaemia is different in several assays. Some assay limitations were not reproduced, and limitations stated in kit inserts cannot be assumed to apply to all analysers.
