摘要 |
A stable blood serum bilirubin reference composition characterized in that the composition possess a pH of from about 8.2 to about 9.2 and comprises (a) a sulfhydryl compound in an amount sufficient to enhance the stability of the bilirubin and (b) a chelating agent in an amount sufficient to bind all the metals present in the blood serum moiety of the composition. This blood serum bilirubin composition when stored in a gas impervious vial under an inert atmosphere has an excellent shelf life. |
