柯达DT-60台式化学分析仪进行了评估与标准化协议，以确定系统的精密度和准确度时，由四名志愿者（秘书，执业护士，和两个家庭医学居民）在模拟办公室实验室操作。发现结果的变异性显著大于医疗技术人员在同一研究期间使用医院实验室中放置的另一DT-60分析相同样品产生的结果的变异性。需要确定增加差异的来源，以便可以修改系统或开发新的控制程序，以确保患者护理中使用的结果的可靠性。潜在的购买者、制造商和患者需要这种关于预期用于医生办公室实验室的系统产生的结果的可靠性的客观信息。
The Kodak DT-60 tabletop chemistry analyzer was evaluated with standardized protocols to determine the system's precision and accuracy when operated by four volunteers (a secretary, a licensed practical nurse, and two family medicine residents) in a simulated office laboratory. The variability of the results was found to be significantly greater than the variability of results produced by medical technologists who analyzed the same samples during the same study period with another DT-60 placed in the hospital laboratory. The source(s) of increased variance needs to be identified so the system can be modified or new control procedures can be developed to ensure the reliability of results used in patient care. Prospective purchasers, manufacturers, and patients need this kind of objective information about the reliability of results produced by systems intended for use in physicians' office laboratories.
