摘　　要：目的对2021年能力验证计划肽酶-3样本的均匀性和稳定性进行研究。方法根据CNAS-CL04和GB/T 14927.1—2008,对肽酶-3样本进行均匀性和稳定性检验。考察4个温度(37℃,室温,4℃和-20℃)条件下和运输条件下的样本稳定性。结果肽酶-3样本,均匀性检验合格。在37℃条件下可以稳定6 h;在室温条件下可以稳定7 d;在4℃条件下,可以稳定4周;-20℃条件下,可以稳定2个月;在运输条件下,可以稳定7 d。结论肽酶-3样本的均匀性和稳定性检验结果满足开展能力验证计划的要求。Objective The homogeneity and stability of peptidase-3 samples of the 2021 proficiency testing were studied.Method The homogeneity and stability of peptidase-3 samples were tested according to CNAS-CL04 and GB/T 14927.1—2008.The stability of the samples under four temperatures(37℃,room temperature,4℃and-20℃)and transport conditions were investigated.Result The peptidase-3 samples were uniformly tested.It can be stable for 6 h at 37℃and stable for 7 d at room temperature.At 4℃,it can be stable for 4 weeks.Under the condition of-20℃,it can be stable for 2 months and stable for 7 d under transportation conditions.Conclusion The homogeneity and stability of the peptidase-3 samples met the requirements of the proficiency testing.
