Test Category: Specialist Biochemistry
Investigation Name:Anti- Infliximab Antibodies
Alias or Abbreviation:Remicade
Accreditation:UKAS ISO15189:2022 accredited test: On scope
Intro:
Infliximab (Remicade®) is a chimeric human-mouse monoclonal antibody directed against tumour necrosis factor-alpha (TNF-α), approved for use in the treatment of various chronic inflammatory diseases including rheumatoid arthritis, severe Crohn’s disease and ankylosing spondylitis.A significant proportion of patients on Infliximab go on to develop antibodies against the drug, which leads to a loss of therapeutic efficacy due to neutralisation of therapeutic effect and/or increased drug clearance and an increased risk of infusion reactions. Anti-Infliximab antibodies are measured on all patient samples who report an Infliximab drug level result of ≤1 µg/mL.
Anti-Infliximab antibody analysis can also be performed on all samples by prior arrangement with the laboratory. Please contact us to discuss if required
