■ Abnormal protein manufactured in the liver in response to
inflammation and infection. Useful in evaluating
autoimmune and infectious diseases and in monitoring
treatment effectiveness.
■ CRP levels usually rise to 100 mg/L or more in the presence
of inflammation and infection. For this purpose, the plain
CRP test is used because it measures CRP in the 10–1000
mg/L range.
■ The high-sensitivity CRP test is used to assess risk of
atherosclerosis in otherwise healthy adults. It measures
CRP in the 0.5–10 mg/L range. Higher levels within this
range are associated with an increased risk of
atherosclerosis.
