What does CRP measure in the body?

C-Reactive Protein, commonly referred to as CRP, is a substance produced by the liver in response to inflammation. Its primary role is to increase in concentration during inflammatory conditions, infections, and chronic diseases. Measuring CRP levels in the blood provides valuable information about the presence and intensity of inflammation in the body, making it a crucial indicator for diagnosing and monitoring various health issues, including infections, autoimmune diseases, and certain chronic conditions.

In terms of the other options, "Chronic reactive protein" and "Calcium-reactive protein" do not accurately represent what CRP stands for or its properties. "Cellular response protein" is also not a recognized term associated with CRP. The correct naming, C-Reactive Protein, succinctly captures its identity and function in the inflammatory response, emphasizing the importance of inflammatory markers in medical diagnostics.
