Four portable analyzers, HemoCue B-Glucose (I), Accu-Check III (II), One-touch II (III), and Glucometer Elite (IV), with different measuring principles were tested for their suitability for measuring blood glucose in neonates. Precision of all instruments is satisfactory. In the analysis of capillary blood from newborns, two instruments show an excellent accuracy; however, the scatter of the results for instrument (II) is about 1.6 times greater than for instrument (I). The inaccuracy of instruments (III) and (IV) is not acceptable from a clinical point of view. All devices show an influence of hematocrit, the magnitude of which varies between 5% (I) and 12% (III) for every 10% change of hematocrit. Instruments II and IV show that temperature has a marked influence on the readings; the same is true for oxygen in instrument IV. In conclusion, only instrument (I) has met the requirements of accurate and precise blood glucose determinations in neonates.
对四种采用不同测量原理的便携式分析仪，即HemoCue B - 葡萄糖（I）、Accu - Check III（II）、One - touch II（III）和血糖仪Elite（IV），进行了其在新生儿中测量血糖适用性的测试。所有仪器的精密度令人满意。在分析新生儿的毛细血管血时，有两种仪器显示出极佳的准确性；然而，仪器（II）结果的离散度比仪器（I）约大1.6倍。从临床角度来看，仪器（III）和（IV）的不准确性是不可接受的。所有设备均显示出血细胞比容的影响，血细胞比容每变化10%，其影响程度在5%（I）至12%（III）之间变化。仪器II和IV显示温度对读数有显著影响；仪器IV中的氧气对读数也有同样影响。总之，只有仪器（I）满足新生儿准确和精确测定血糖的要求。
