»Albumin Human conforms to the regulations of the federal Food and Drug Administration concerning biologics (640.80to 640.86)(see Biologicsá1041ñ).It is a sterile,nonpyrogenic preparation of serum albumin obtained by fractionating material (source blood,plasma,serum,or placentas)from healthy human donors,the source material being tested for the absence of hepatitis Bsurface antigen.It is made by a process that yields a product that is safe for intravenous use.Not less than 96percent of its total protein is albumin.It is a solution containing,in each 100mL,either 25g of serum albumin osmotically equivalent to 500mLof normal human plasma,or 20g equivalent to 400mL,or 5g equivalent to 100mL,or 4g equivalent to 80mLthereof,and contains not less than 93.75percent and not more than 106.25percent of the labeled amount in the case of the solution containing 4g in each 100mL,and not less than 94.0percent and not more than 106.0percent of the labeled amount in the other cases.It contains no added antimicrobial agent,but may contain sodium acetyltryptophanate with or without sodium caprylate as a stabilizing agent.It has a sodium content of not less than 130mEq per Land not more than 160mEq per liter.It has a heme content such that the absorbance of a solution,diluted to contain 1percent of protein,in a 1-cm holding cell,measured at a wavelength of 403nm,is not more than 0.25.It meets the requirements of the test for heat stability and for pH.
