The erythrocytes 99mTc labeling in vitro process with stannous chloride (II) and sodium hypochlorite using was studied. Optimal concentrations of the using reagents and the incubation periods were determined. Labeling efficiency of 95 % which decreases within a day to 87 % was reached. The preparation technique of stannous chloride work solution by means of salt dissolution in 6 % citric acid solution was suggested.
