Purpose of the test
Anti-TNF therapy is one of a new class of drugs (biologic agents) that target specific proteins in the immune system known to increase arthritis and other inflammatory diseases such as inflammatory bowel disease, vasculitis, juvenile dermatomyositis. By blocking these proteins these drugs reduce inflammation but without causing side effects by blocking other important processes. Monitoring levels is useful to assess correct dosage and guide infusion intervals. Measurement of anti-drug antibodies identifies patients which may experience infusion reactions and/or a reduced duration of efficacy, due to drug immunogenicity.
Test panel includes both drug and anti drug antibody measurment. Interpretation will be provided. Other anti-TNF alpha drug measurements available (Infliximab, etanercept).
