Table 1 RPC testing methods for Mallinckrodt Technescan MAG3 preparations available in Switzerland, European countries, the US (Package insert for Technescan MAG3. Mallinckrodt Suisse SA, 2003; Package insert for Technescan MAG3. Mallinckrodt Suisse SA, 2015; European Pharmacopoeia Edition 7.0, 2008; Package insert for Technescan MAG3, 2015; Package insert for Technescan MAG3, 2015) in comparison to the method of the Ph.Eur. (European Pharmacopoeia Edition 7.0, 2008). Each SPC method requires detection of the sum of liphophilic and hydrophilic impurities
