CRP

C-Reactive Protein (standard CRP) is an acute-phase reactant protein produced by the liver in response to inflammation or infection. Standard CRP tests measure a wide range. While hs-CRP is preferred for low-grade chronic inflammation assessment, standard CRP results below 10 mg/L can still provide information on inflammatory burden, often correlating well with hs-CRP in this range (PMID: 36136302). Levels >10 mg/L usually indicate acute inflammation or infection. Note: Several factors can raise CRP, including recent illness or injury.
