LimitationsHaemolysed samples give split alpha-2 peaks and should be avoided. Icteric samples show significant differences in appearance to normal serum and should not be analysed. Plasma samples should not be analysed as they contain fibrinogen which migrates in the beta-2 region, which could be interpreted as a paraprotein.
