what is crp in blood test

A C-reactive protein (CRP) test measures the level of CRP in a sample of your blood. CRP is a protein made by the liver, and its level increases when there's inflammation in the body. The test is used to find or monitor inflammation in acute or chronic conditions, including infections, inflammatory bowel disease, autoimmune disorders, and lung diseases. It can also help assess the risk of heart disease, and to see how well you are responding to treatment. A high-sensitivity CRP (hs-CRP) test is more sensitive and is used to show the risk of getting coronary artery disease. A high level of hs-CRP in the blood has been linked to an increased risk of heart attacks. A high CRP level is more than 10mg/L, which shows that there is inflammation in the body
