Assay
Assay preparation 1
Dissolve a suitable quantity of Sterile Vancomycin Hydrochloride, accurately weighed, in water, and dilute quantitatively with water to obtain a solution containing about 1 mg of vancomycin per mL.
Assay preparation 2
(where it is packaged for dispensing)Dissolve the contents of 1 container of Sterile Vancomycin Hydrochloride in water, and dilute quantitatively with water to obtain a solution having a concentration of about 1 mg of vancomycin per mL.
Assay preparation 3
(where the label states the quantity of vancomycin in a given volume of constituted solution)Constitute 1 container of Sterile Vancomycin Hydrochloride in a volume of water, accurately measured, corresponding to the volume of solvent specified in the labeling. Dilute an accurately measured volume of the constituted solution quantitatively with water to obtain a solution having a concentration of about 1 mg of vancomycin per mL.
Procedure
Proceed as directed under AntibioticsMicrobial Assays 81, using an accurately measured volume of the appropriate Assay preparation diluted quantitatively with Buffer No. 4 to yield a Test Dilution having a concentration assumed to be equal to the median dose level of the Standard.
