CRP and Sepsis: Plasma from systemic inflammatory response syndrome versus sepsis patients were compared by LC/LC–ESI–MS/MS that showed increased observation frequency for C4, CRP, plasminogen precursor, apolipoprotein A-II, plasma protease C1 inhibitor precursor, transthyretin precursor, while serum amyloid P-component precursor, apolipoprotein A-I precursor, antithrombin-III precursor, and serum amyloid A-4 protein precursor showed lower observation frequency [8].
