Use of point-of-care testing (POCT) in primary care has increased. There is a need for high-quality field evaluation of POCT before deployment can be considered.
A POCT system for C-reactive protein was evaluated in a routine general practice setting. The standard laboratory method was a dry slide method based in a routine hospital laboratory.
Scatterplots for both venous and capillary blood POCT system results versus the standard laboratory assay produced correlation coefficients of greater than 0.96. Bland-Altman plots indicated that 95% of venous and capillary POCT results fell within +/-10 mg/L of the mean value with no clinically significant difference from laboratory results.
The POCT system performed reliably in a routine general practice setting with satisfactory performance against an accepted laboratory method.
基层医疗中即时检验（POCT）的使用有所增加。在考虑推广之前，需要对POCT进行高质量的现场评估。
在常规全科医疗环境中对一种C反应蛋白的POCT系统进行评估。标准实验室方法是基于常规医院实验室的干片法。
静脉血和毛细血管血POCT系统结果与标准实验室检测的散点图产生的相关系数大于0.96。Bland-Altman图表明，95%的静脉血和毛细血管血POCT结果落在平均值的±10mg/L范围内，与实验室结果无临床显著差异。
该POCT系统在常规全科医疗环境中表现可靠，与公认的实验室方法相比性能令人满意。
