Abstract

We evaluated the new Beckman multichannel analyzers Astra 8 and Astra 4. Both instruments performed the following tests: Na, K, Cl, CO2, urea, glucose, and creatinine in plasma and Na, K, Cl, and creatinine determinations in urine. We tested precision, accuracy, and linearity at the usual concentrations in plasma and urine. We compared the Astra 8 and Astra 4 with continuous-flow (SMA 6) and discrete analyzers such as IL 243, Beckman KLiNa Flame, Beckman System 1, Corning 920 M Chloride Meter, and the Corning Blood-Gas Analyzer 175. Special tests were performed on plasma-to-plasma and urine-to-plasma carryover. Both analyzers are easy to operate and suitable for both emergency and routine use.

摘要

我们评估了新型贝克曼多通道分析仪Astra 8和Astra 4。这两种仪器都能进行以下检测：血浆中的钠、钾、氯、二氧化碳、尿素、葡萄糖和肌酐，以及尿液中的钠、钾、氯和肌酐测定。我们在血浆和尿液的常规浓度下测试了精密度、准确度和线性度。我们将Astra 8和Astra 4与连续流动分析仪（SMA 6）以及诸如IL 243、贝克曼KLiNa火焰光度计、贝克曼系统1、康宁920 M氯化物测定仪和康宁175型血气分析仪等离散分析仪进行了比较。还对血浆到血浆以及尿液到血浆的携带污染进行了专项检测。这两种分析仪操作简便，适用于急诊和常规检测。
