A pretinning method for labelling erythrocytes with technetium-99m (99mTc) in vitro has been developed using a kit which contains stannous chloride stabilized with gentisic acid. Labelling efficiency was 97.3% (SD 1.4%) for 80 patients. The method requires less time than the Brookhaven kit and results in a smaller volume for reinjection but provides equivalent clinical results. We have previously shown that leukocytes labelled with 99mTc using the same gentisic acid kit are clinically equivalent to those labelled with HMPAO; thus, the kit is versatile and cost-effective.
已开发出一种体外使用含有龙胆酸稳定的氯化亚锡试剂盒，用锝-99m（99mTc）标记红细胞的预锡化方法。80例患者的标记效率为97.3%（标准差1.4%）。该方法所需时间比布鲁克海文试剂盒少，再注射体积更小，但临床结果相当。我们之前已经表明，使用同一龙胆酸试剂盒用99mTc标记的白细胞在临床上与用HMPAO标记的白细胞相当；因此，该试剂盒用途广泛且具有成本效益。
