interferences

• sources of error for CK assays: hemolysis and sunlight
• interferences for lactate dehydrogenase: hemolysis and cold temperatures
• sources of error for LD assays - hemolysis and cold temperatures
• AST sources of error include hemolysis
• alkaline phosphatase sources of error include hemolysis, diet of group B and O secretors (fatty diet will elevate), specimen sitting at RT
• acid phosphatase was Historically used to evaluate prostate cancer, sexual assault cases, bone disease ( they are a part of osteoclasts) or platelet damage
• sources of error for acid phosphatase include hemolysis, increased time at RT
• amylase sources of error include opiate use and lipemia
• lipase sources of error include hemolysis
• hemolysis and sunlight are interferences of CK
• hemolysis is an interference for creatine kinase, lactate dehydrogenase, aspartate aminotransferase, alkaline phosphatase, acid phosphatase, and lipase (6)
