It is produced in greater amounts when there is inflammation, and high concentrations indicate that the patient's system is more inflamed. C-reactive protein test measures the concentration of C-reactive protein in plasma and is a useful non-specific indicator of inflammation and detection of infections High-sensitivity CRP is a more sensitive form of the standard CRP test.
