Which test is used to evaluate the body's inflammatory response?

The erythrocyte sedimentation rate (ESR) is specifically designed to assess the presence and extent of inflammation in the body. It measures how quickly red blood cells settle at the bottom of a test tube containing a blood sample. When inflammation is present, certain proteins in the blood, such as fibrinogen, increase, causing red blood cells to clump together and settle more rapidly. This test is valuable in diagnosing and monitoring conditions associated with inflammation, such as autoimmune diseases, infections, and some types of cancer.

In contrast, the lipid profile evaluates cholesterol and triglyceride levels to assess cardiovascular health, the complete blood count provides information on various blood components, including red and white blood cells, and the metabolic panel assesses metabolic functions, including kidney and liver health. These tests serve different purposes and do not specifically measure inflammation.
