Among laboratory mistakes, "specimen mix-up" is the most frequent and the most serious. According to the Clinical Chemistry Laboratory Error Report of Toranomon Hospital, specimen mix-up was often detected when there were many large discrepancies between the results of a test and the results of a previous test. We present here a checking method to detect specimen mix-up. The method, which we call the "multivariate delta check" method, is an extension of the "delta check" method first presented by Nosanchuk and Gottmann (Am. J. Clin. Pathol. 62:707, 1974). Clinical evaluation has demonstrated the effectiveness of the method.
在实验室错误中，“样本混淆”最为常见且最为严重。根据东京虎之门医院的临床化学实验室错误报告，当一项检测结果与先前检测结果存在许多重大差异时，经常会检测到样本混淆。我们在此介绍一种检测样本混淆的检查方法。该方法我们称为“多变量差值检查”法，是诺桑丘克和戈特曼首次提出的“差值检查”法（《美国临床病理学杂志》62:707，1974年）的扩展。临床评估已证明该方法的有效性。
