LISA-TRACKER anti-Etanercept is an enzyme linked immunoassay (ELISA) for the quantitative determination of anti-Etanercept antibodies in human serum samples to aid in monitoring immunogenic responses to therapy. Compatible with biosimilars and open automation platforms, the test uses 100 µL samples and detects levels between 10–100 ng/mL. Ready-to-use reagents and standardized protocols make it suitable for therapeutic drug monitoring in autoimmune and inflammatory diseases.
