When your body is healthy it functions normally in a state of homeostasis or equilibrium. The crp response frequently precedes clinical symptoms, including fever. Reference ranges for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples reference ranges for blood tests are studied within the field of clinical chemistry also known as clinical biochemistry, chemical pathology or pure blood chemistry, the area of pathology that is generally concerned with analysis of bodily fluids.

Creactive protein, along with other markers of inflammation erythrocyte sedimentation rate, sed rate, or esr are also sometimes referred to as acute phase. The creactive protein crp test is ordered to evaluate people who have signs and symptoms of a serious bacterial infection or of a serious chronic inflammatory disease such as rheumatoid arthritis. A variation of the crp test, the highsensitivity crp hscrp, is used to check for cardiovascular disease.
Creactive protein measures general levels of inflammation in your body. Creactive protein crp is a marker of inflammation in the body. High crp levels can also indicate that theres inflammation in the arteries of the heart, which can mean a higher risk of heart attack. Any crp positive test that posts results of 10mgl and above is classified as high. This protein is produced by the liver and its levels will rise in response to increased levels of inflammation. This is a blood test marker that indicates there is inflammation occurring somewhere in the body. When there is inflammation in the body, the crp levels increase. What is crp normal range rapid and hs creactive protein. The sed rate is usually faster high during disease flares and slower low during remissions.
