Troponin bound to heparin causes decreased measured troponin plasma concentration in comparison to serum.[seventy six] Other sources of interference that could affect the assay detection course of action and trigger Bogus-negative troponin values include things like ascorbic acid in immunoenzymometric assays utilizing alkaline phosphatase, biotin in assays using a biotinylated antibody, streptokinase from the existence of streptavidin, and higher titers of antibodies to ruthenium or streptavidin in cTnT assays.
