WebHemolysis is one of the most commonly encountered pre-analytical sources of interference in the Clinical Biochemistry laboratory. Hemolysis is known to cause a variable interference in both cardiac troponin I (cTnI) and troponin T (cTnT) assays. Each laboratory should determine and publicize these effects. WebHemoglobin binds to haptoglobin, therefore haptoglobin exhibits a negative interference on the measured haptoglobin concentration. Presence of hemolysis also causes a negative or positive interference on the Troponin T and I assays. The degree and direction of the interference is method dependent.
