Not provided.
Limitations
The presence of anti-infliximab antibodies does not guarantee a failure of infliximab therapy, and their absence does not guarantee treatment success. High serum biotin concentrations may interfere with the assay. Assay failure to detect infliximab or anti-infliximab antibodies could be due to factors not related to therapeutic failure or antibody presence.
