High-sensitivity C-reactive protein (HSCP), which is an indicator of a laboratory test. For example, if you suspect a problem with certain organs, you can use a C-reactive protein test to make a preliminary determination. However, its specificity is not high and its sensitivity is very low. It is mainly seen in acute inflammatory and infectious diseases, such as acute upper respiratory tract infections, pneumonia, and acute nephritis. Of course, in some acute events, high-sensitivity C-reactive protein may also be elevated. For example, in acute myocardial infarction and trauma, C-reactive protein is also elevated, but it is only a marker with high sensitivity but poor specificity. Therefore, it is not reliable to determine the disease simply by high-sensitivity C-reactive protein, but must be combined with the patient’s underlying disease, as well as symptoms and manifestations of other sites to make a preliminary judgment.
