Inflammatory markers are substances in the body that indicate the presence of inflammation. They can be measured through blood tests and help healthcare providers assess conditions like infections, autoimmune diseases, and chronic illnesses. Common inflammatory markers include C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Elevated levels of these markers suggest that the body is responding to injury or disease. Monitoring inflammatory markers can assist in diagnosing conditions, tracking disease progression, and evaluating the effectiveness of treatments. Understanding these markers is essential for managing health and guiding medical decisions.
