摘　　要：目的调查我室常规检测生化项目实验方法的线性程度,探讨多项式评价线性在实验医学中的应用。方法根据多项式线性评价方法,利用统计软件进行数据拟合,结合临床目标判断数据精密度和线性程度。结果不同项目的线性判定结果不尽相同。结论线性评估可有效保证实验方法准确、可靠;多项式线性评价方法充分利用统计理论,结合临床可科学评价实验方法线性程度。Objective To investigate the linear degree of the routine biochemical items of our laboratory. Methods According to polynomial linear evaluation method, we found the best-fit polynomial of the data making use of statistical software, then estimated the imprecision and linear degree of the data combined with the clinical goals. Results The linear degree of different items was not the same. Conclusions Linear evaluation can ensure the laboratorial methods accurate and credible efficiently. The polynomial method can evaluate the linear degree of the laboratorial methods using statistical theory and considering clinical significance.
