AlbuminAlbumin is a negative acute phase reactant whereas ferritin, CRP and haptoglobin are positive phase reactants."The serum levels of most proteins either increase or decrease during the acute phase response. Serum proteins that decrease levels during inflammation are called negative acute phase reactants.C-reactive protein, fibrinogen, protein S, and fibronectin are examples of positive acute phase reactants.Positive Acute Phase ReactantsC-reactive protein (CRP)Serum amyloid AHaptoglobinCeruloplasminalpha 2-Macroglobulinalpha l-Acid glycoproteinFibrinogenComplement (C3, C4)
