本文报告我们试剂的尿中吗啡检测用HI药盒冻干及未冻干试剂保存时稳定性的观察结果。每批冻干试剂抽样单独保存。保存条件4℃冰箱中、室温(5-25℃)及37℃恒温箱中保存。检测时间为制备后1,2,3,6,9,12个月,按期进行下列检测。 1.用已知滴度的新致敏SRBC检测每批冻干抗血清的滴度,与该批血清冻干前检测的滴度对比。 2.用已知滴度的抗血清检测每批未冻干致敏细胞的滴度,与该批致敏细胞当日检测的滴度对比。 3.用正规法检验全套药盒的反应效果,观察药盒试剂经保存时间后是否仍能符合质控标准的要求,是否仍可获得正确的试验检测结果。
This article reports the observation of the stability of our reagent in morphine detection in urine using the HI kit freeze-dried and non-lyophilized reagents. Each batch of lyophilized reagent sample is saved separately. Storage conditions 4 ℃ refrigerator, room temperature (5-25 ℃) and 37 ℃ incubator to save. The detection time was 1, 2, 3, 6, 9 and 12 months after the preparation, and the following tests were conducted on schedule. 1. The titer of each batch of lyophilized antiserum was tested with freshly sensitized SRBC of known titer, compared to the titers detected prior to lyophilization of the batch. 2. The titers of each batch of un-lyophilized sensitized cells were tested with antisera of known titer, in contrast to the titers detected on the day of sensitization of the batch of cells. 3. Using the formal test to test the response of the full kit, and to see if the kit reagents still meet the quality control standards after they have been stored for a while, and still be able to obtain the correct test results.
