Antibody levels in reduced/alkylated intravenous immune globulin

Antibody titers, found in representative lots of a reduced and alkylated intravenous immune globulin, against a variety of common microorganisms are presented. With the more frequently occurring pathogens the specific antibody level does not vary significantly between lots. Depending upon the type of assay used, antibody titers per se may or may not reflect the therapeutic activity of the preparation against a specific microorganism.
