淀粉酶试剂开瓶上机后稳定性讨论

目的：分析淀粉酶试剂开瓶上机后的稳定性，采取相应措施避免由于试剂不稳定导致的不良后果。方法：分别用70ml或20ml瓶装淀粉酶试剂，检测该项目一段时间并统计分析室内质控结果。结果：小瓶装试剂所测结果重复性良好，未出现向下漂移现象。结论：淀粉酶试剂机内稳定期为25天左右，应根据实际情况改用小试剂瓶。

The discussion of amylase reagent stability within the instrument after open

objective： to analyze the stability of amylase reagent within the instrument after open, take corresponding measures to avoid the adverse consequences due to unstable reagent. Methods： 70 ml or 20 ml bottled amylase reagent, detection of the project for a period and statistical analysis results of indoor quality control. Results： Small bottles of reagents and the repeatability of the results is good, does not appear downward drift phenomenon. Conclusion： amylase reagent stability within the instrument is 25 days or so, should according to actual circumstances, apply small reagent bottle.
