The HemoCue system for estimating haemoglobin was evaluated within urban general practice. It gave excellent results when used within a laboratory environment (on 103 paired samples) but disappointing ones when evaluated by practice nurses within general practice (on 235 paired samples). The most likely source of error was inadequate mixing of the blood specimens before sampling, which might be obviated by using a rotating mixer. It is emphasised that equipment intended for use in general practice should be evaluated under normal working conditions envisaged.
用于估算血红蛋白的HemoCue系统在城市全科医疗中进行了评估。在实验室环境中使用时(对103对样本),它给出了出色的结果,但在全科医疗中由实习护士评估时(对235对样本),结果却令人失望。最可能的误差来源是采样前血液标本混合不充分,这可以通过使用旋转混合器来避免。需要强调的是,打算在全科医疗中使用的设备应在设想的正常工作条件下进行评估。
