title: Effect of haemolysis on plasms and serum immunoglobulin estimations.
abstract: Plasma IgG, IgM and IgA estimations were carried out in blood samples with varying degrees of haemolysis, produced by controlled ultrasonication. Extent of haemolysis was determined by plasma haemoglobin, plasma potassium and packed cell volume; and plasma IgG, IgM and IgA estimations showed a steady and significant fall with increasing haemolysis. A calculated correction is proposed which compensates for the dilutional effect of haemolysis, during estimations of plasma and serum immunoglobulins.
