自制血清总胆红素质控品研究

目的自制胆红素室内质控品作为测定总胆红素（TBIL）参比血清，评价自制室内质控品是否符合临床要求，降低检验成本。方法收集日常工作中TBIL高、中、低值标本分别混合后分装并加入赋形剂，经低温干燥至干粉，低温避光冷藏，即为自制质控品。结果自制室内质控品在26d内与新鲜混合血清的TBIL比较，差异无统计学意义（P〉0．05）。结论自制TBIL室内质控品符合室内质控要求，该分装方法用于自制室内质控品，可降低检验成本。

Study on the quality control of bilirubin in self-made serum

Objective Using bilirubin self-made laboratory quality control of products as a total bilirubin (TB) Reference Serum to evaluate the self-made laboratory quality control about whether to fit the clinical requirements and to reduce the cost of testing.Methods Collect the high,medium,low and mixed loaded total bilirubin(TB) respectively at the routine working days, and then add some excipients and put it in the place under low temperature till dry powder, which should be stored in cold 、dark and frozen environment.Results Within 26 days, compared the self-made laboratory quality control products(frozen mixed serum) with the fresh mixed blood plasma total bilirubin (TB),the difference was not significant (P＞ 0.05).Conclusion Total bilirubin self-made laboratory quality control of products meet with the requirements, so this sub-loaded method can be used for quality control laboratory of self-made products, and reduce testing costs.
