The authors evaluated the quality and reliability of four desktop analyzers in the outpatient clinic. Twenty-seven nontechnologists (NTs) participated in the study. These included nurses, physicians, and medical students. The instruments and tests evaluated were as follows: Reflotron (glucose, cholesterol, triglycerides, gamma-glutamyltransferase and urea); Seralyzer (creatinine, glucose, potassium, aspartate aminotransferase, and hemoglobin); Vision (glucose, urea, cholesterol, triglycerides, alkaline phosphatase, and uric acid); and DT60 (sodium, potassium, glucose, amylase, uric acid, bilirubin, and creatinine). For precision studies, low and high control material was used, and method comparison was done with methods in routine use in the laboratory. The range of coefficients of variation (CVs) for the analyzers with NTs was as follows: Reflotron: CV, 2.4-7.9%; Seralyzer CV, 1.4-18.7%; Vision: CV, 1.5-2.7%; DT60: CV, 2.5-46.8. The percentage results that is different by greater than 10% between the NTs and trained technologists was related to the complexicity of procedure for each analyzer and was the lowest for the Vision analyzer and greatest for the Seralyzer.
作者评估了门诊中四台台式分析仪的质量和可靠性。27名非技术人员（NTs）参与了该研究。这些人员包括护士、医生和医学生。所评估的仪器和测试如下：Reflotron（葡萄糖、胆固醇、甘油三酯、γ-谷氨酰转移酶和尿素）；Seralyzer（肌酐、葡萄糖、钾、天冬氨酸转氨酶和血红蛋白）；Vision（葡萄糖、尿素、胆固醇、甘油三酯、碱性磷酸酶和尿酸）；以及DT60（钠、钾、葡萄糖、淀粉酶、尿酸、胆红素和肌酐）。对于精密度研究，使用了低浓度和高浓度的质控品，并与实验室常规使用的方法进行了方法比较。非技术人员使用的分析仪的变异系数（CV）范围如下：Reflotron：CV为2.4 - 7.9%；Seralyzer：CV为1.4 - 18.7%；Vision：CV为1.5 - 2.7%；DT60：CV为2.5 - 46.8。非技术人员与训练有素的技术人员之间结果差异大于10%的百分比与各分析仪的操作复杂性有关，Vision分析仪的该百分比最低，Seralyzer的最高。
