We evaluated the performance of the Kodak DTSC Module for determination of alanine aminotransferase (ALT; EC 2.6.1.2), aspartate aminotransferase (2.5.1.2), alkaline phosphatase (3.1.3.1), creatine kinase (2.7.3.2), gamma-glutamyltransferase (2.3.2.2), and lactate dehydrogenase (1.1.1.27). The DTSC is a "special chemistry" accessory for the DT60 analyzer; the same multilayer film technology as that of the Ektachem 700 is used. The overall precision, assessed over a three-month period with two serum-based quality control materials, ranged from 2.2 to 8.0%. DTSC results for patients' specimens correlated well with those by the Technicon RA-1000 analyzer. The performance of the analyzer in linearity and interference studies was satisfactory for clinical use. The DTSC is simple to operate and has no technique-dependent step; it should be useful for the physician's office laboratory.
我们评估了柯达DTSC模块用于测定丙氨酸氨基转移酶（ALT；EC 2.6.1.2）、天冬氨酸氨基转移酶（2.5.1.2）、碱性磷酸酶（3.1.3.1）、肌酸激酶（2.7.3.2）、γ-谷氨酰转移酶（2.3.2.2）和乳酸脱氢酶（1.1.1.27）的性能。DTSC是DT60分析仪的一种“特殊化学”附件；采用了与Ektachem 700相同的多层膜技术。使用两种基于血清的质量控制材料，在三个月的时间内评估的总体精密度范围为2.2%至8.0%。患者样本的DTSC结果与Technicon RA - 1000分析仪的结果相关性良好。该分析仪在线性和干扰研究方面的性能对于临床使用来说是令人满意的。DTSC操作简单，没有依赖技术的步骤；它对医师办公室实验室应该会很有用。
