C-reactive protein of 120 mg/l is above normal and not normal. Normal values for C-reactive protein should be less than 10 mg/l, with normal ranges varying slightly by testing organization.C-reactive protein reacts with S. pneumoniae cell wall C polysaccharide in the acute phase and is synthesized by the liver. It is synthesized by the liver. C-reactive protein is a more sensitive indicator of the acute phase reaction and can be used to distinguish non-bacterial from bacterial infections.
