This prospective study was aimed to assess inter- and intra-operator variability during routine quality control (QC) procedure for technetium-99m mercaptoacetyl triglycine ((99m)Tc-MAG3) instant kit formulation. A total of 160 QC analyses with thin layer chromatography (TLC) for 20 separate MAG3 re-constitutions were performed by 2 radiochemists. The percentage of free and hydrolysed (99m)Tc as well as binding efficiency, were calculated according to standard TLC.
