摘要: The interference of the non-ionic magnetic resonance contrast medium gadodiamide injection (OMNISCAN®, Nycomed Imaging, Oslo, Norway) in colorimetric determination serum calcium has been investigated commercial reconstituted serum, and from rabbits humans dosed with medium. Inductively coupled plasma-atomic emission spectroscopy (ICP-AES) ion-selective electrodes were used as reference methods for analysis calcium. results showed that reagent kit gave an apparent decrease after administration a clinical dose injection, extent is correlated to concentration However, was not changed when measured by means electrode or ICP-AES. It therefore recommended kits should be samples taken within first 24 h inj...
