It contains not less than 90.0 percent and not more than 110.0 percent of the labeled amount of ^99mTc as stannous gluceptate complex expressed in megabecquerels (microcuries or millicuries) per mL at the time indicated in the labeling. It may contain antimicrobial agents and buffers. Other chemical forms of radioactivity do not exceed 10.0 percent of the total radioactivity.
