Witryna1 mar 2003 · Abstract. Objective:If additional chemicals are inadvertently introduced in the preparation of radiopharmaceutical kits, radiochemical impurities may be formed.We report our experience with erroneously diluting 99m Tc-pertechnetate eluate with 5% dextrose solution rather than normal saline during the preparation of 99m Tc … Witrynaimpurities had been identified in certain technical materials that would have been overlooked in the present Tier-2 equivalence evaluation. This is due to the fact that certain impurities meeting the criteria for relevance do not produce observable effects in acute, short term toxicity test protocols. Such an example is fluazinam TC
