About This Test
The high-sensitivity C-reactive protein (hs-CRP) test is a blood test that measures the level of hs-CRP in the blood. CRP is a protein produced by the liver that increases in response to inflammation in the body. The hs-CRP test is a more sensitive version of the CRP test, meaning it can detect lower levels of CRP in the blood.
High levels of hs-CRP in the blood may be a sign of inflammation in the body, which can be caused by various conditions, such as infections, injuries, autoimmune disorders, and certain chronic diseases. The hs-CRP test is often used to help evaluate a person’s risk of developing cardiovascular disease, as high levels of hs-CRP have been associated with an increased risk of heart attack and stroke. A healthcare provider usually orders the hs-CRP test as part of a routine health check-up or if they suspect a person may have inflammation in the body.
