Abstract

We report modifications of ionized calcium as observed on specimens collected in a commercially available sampling device (Radiometer B-129). When the sampler is used as recommended, errors are non-significant around 1.25 mmol l-1. There is a +3% increase for low (0.75 mmol l-1) values and a -2% decrease for high (2.50 mmol l-1) values. Incomplete syringe-filling increases these errors.

摘要

我们报告了在市售采样装置（Radiometer B - 129）中采集的标本上观察到的离子钙的变化情况。当按照推荐使用采样器时，在1.25 mmol/l左右误差不显著。低浓度（0.75 mmol/l）值增加了3%，高浓度（2.50 mmol/l）值降低了2%。注射器填充不完全会增加这些误差。
