嗜酸性粒细胞阳离子蛋白(eosinophil cationicprotein,ECP)是存在于嗜酸性粒细胞颗粒中的一种细胞毒性蛋白。由于血样采集处理过程中的许多因素可影响血中ECP浓度[1~2],因此,严格控制各种影响因素、选择最适条件非常重要。为了便于结果的前后比较和快速检测,我们实验室采用在37 Eosinophil cationic protein (ECP) is a cytotoxic protein present in eosinophilic granules. As many factors in the blood sampling process can affect ECP concentrations in the blood [1-2], it is important to strictly control various influencing factors and select the most appropriate conditions. In order to facilitate the comparison of the results before and after rapid testing, our laboratory used in 37
