    Introduction: Macro-creatine kinase (Macro-CK) is a complex with longer half-life that leads to elevation of enzyme activity and analytical errors. We present two cases with macro-CK to picture the problem. The aim of the study was to evaluate and compare different methods using polyethylene glycol (PEG) for screening. Methods: Serum samples (n=39) were analysed using different PEG methods PEG6000, 30 minutes centrifugation, 3000 rpm, PEG8000, 10 minutes incubation and 5 minutes centrifugation, 1000 g Modified method 1, 10 minutes centrifugation. The recovery percentage and the polyethylene glycol precipitation activity (PPA) were calculated. In four patients macro-CK was confirmed by electrophoresis (Sebia). Results: The recovery percentage was significantly higher in all non-macro-CK samples than.. View More»
