[Content of IgE in preparations of human immunoglobulin for intravenous use (IVIG)]
The study was aimed at determination of concentration of total IgE and IgE specific for D. pteronyssinus in preparation IVIG Bioglobulin. Twelve series of Bioglobulin and 20 series (8 preparations) registered in Poland, were tested. It was found that all series of Bioglobulin contained IgE in amount from 34.5 iu/ml to 105 iu/ml. In only one series IgE specific against D. pteronyssinus was detected in amount of 0.93 j/ml. It is concluded that concentration of IgE in preparation Bioglobulin is comparable to amount of IgE in other IVIG preparations.
