IL6 and rheumatoid arthritis: The quantification of biomarkers provides criticalindicators formonitoring disease progression, evaluating treatment efficacy, andgaining insights into pathology models. IL-6 plays key roles in the acute phase response, inflammation,hematopoiesis, bone metabolism, and cancer progression, and servesas a biomarker for diseases including rheumatoid arthritis, sepsis,and cancer. In this respect, a titrationcurve is obtained using standard concentration samples of mouse IL-6with the wireless sensor to achieve this.
