We evaluated the performance characteristics of the Coulter Kem-O-Lab for the measurements of calcium, inorganic phosphate, total protein, albumin, glucose and urea nitrogen in serum. The precision on replicates agreed with those claimed by the manufacturer. All methods showed acceptable total precision measured over a four-week period, except for urea nitrogen. There was significant correlation between the Kem-O-Lab and routine methods, but the slope was significantly different from unity for calcium, total protein and urea nitrogen indicating a bias in their determinations. While turbidity and hemoglobin significantly interfered with measurements in all methods, bilirubin interference was observed only for total protein and glucose. There were no interferences due to any of the nine drugs tested.
我们评估了库尔特Kem - O - Lab在测定血清中钙、无机磷、总蛋白、白蛋白、葡萄糖和尿素氮方面的性能特征。重复测量的精密度与制造商声称的一致。除尿素氮外，所有方法在四周期间测量的总精密度均可接受。Kem - O - Lab与常规方法之间存在显著相关性，但钙、总蛋白和尿素氮的斜率显著不同于1，表明其测定存在偏差。虽然浊度和血红蛋白在所有方法中均对测量有显著干扰，但仅在总蛋白和葡萄糖测量中观察到胆红素干扰。所测试的九种药物均未产生干扰。
