| Issue: | Internal investigations have found there is no direct binding competition between Xolair® and the Anti-IgE antibodies of the IgE II assay. However, Xolair® forms soluble complexes with IgE antibodies, and this leads to reduced recovery of the IgE II assay. This effect can only be seen when creating serial dilutions of a sample and checking the linearity of these different dilutions. It will not necessarily be detected by performing a single dilution of the sample. |
