Regular CRP test is mainly used to detect acute inflammatory conditions, such as infections, injuries or diseases that can cause inflammation. The result of a regular CRP test is measured in milligrams per liter (mg/L).
High-sensitivity CRP test is more sensitive than the regular CRP test and can detect lower levels of CRP in the blood. It is primarily used as a marker of cardiovascular health and can indicate risk of cardiovascular disease. High-sensitivity CRP test is performed in the same way as the regular CRP test, but the results are measured in milligrams per deciliter (mg/dL).
So, the difference between high-sensitivity CRP and regular CRP lies in their sensitivity and use. Regular CRP is mainly used to detect acute inflammation, while high-sensitivity CRP is more useful for assessing the risk of cardiovascular disease.
