<prompt> Acute phase reaction in acute inflammation areAlbuminFibrinogenHaptoglobulinAll  <response>: Ans. is a i.e., Albumin,b i.e., Fibrinogen c i.e., Haptoglobulin Acute phase reactants are a class of proteins whose plasma concentration increases or decreases in response to inflammation. This response is called the acute phase reaction acute phase response It should be noted that acute phase proteins not only increase in response to inflammation ; some decrease also? 1 Proteins which increase in response to inflammation -- Positive acute phase proteins 2 Proteins which decrease in response to inflammation -- Negative acute phase proteins
