The High Sensitive CRP (hsCRP) test is a blood test used to measure the level of C-reactive protein (CRP) in the blood at very low concentrations. CRP is a protein produced by the liver in response to inflammation in the body, and hsCRP is a more sensitive test that can detect even small amounts of this protein. This test is often used as a marker for inflammation in the body, and can help identify the risk of cardiovascular disease, such as heart attack or stroke. The hsCRP test is also useful in monitoring the effectiveness of treatment for chronic inflammatory conditions such as rheumatoid arthritis, lupus, or inflammatory bowel disease. The hsCRP test is a simple and quick blood test that can be done in a doctor’s office or a laboratory, and is considered a reliable indicator of low-grade inflammation. However, it is important to note that an elevated hsCRP level does not necessarily mean that a person has a specific disease or condition, and further testing may be necessary to determine the underlying cause of inflammation.
