Stabilized liquid quality control sera, some with elevated bilirubin concentrations, were distributed to laboratories for total and conjugated (direct) bilirubin analyses. Interlaboratory variability was high; for example, results ranged from 10.9 to 24.0 mg/100 ml for a serum with a mean bilirubin concentration of 18.1 mg/100 ml. Coefficients of variation were typically 10% to 12% for total bilirubin ad approximately 24% for conjugated bilirubin analyses. It is believed that these stabilized sera, when used as quality control materials, can help reduce the unacceptably large interlaboratory variability found in this study.
已将一些胆红素浓度升高的稳定化液体质量控制血清分发给各实验室，用于总胆红素和结合（直接）胆红素分析。实验室间的变异性很高；例如，一份平均胆红素浓度为18.1mg/100ml的血清，其结果范围为10.9至24.0mg/100ml。总胆红素的变异系数通常为10%至12%，结合胆红素分析的变异系数约为24%。据信，这些稳定化血清用作质量控制材料时，有助于减少本研究中发现的实验室间不可接受的巨大变异性。
