A comparison of rapid point-of-care serology tests using finger prick and venous blood was done on 278 participants. In a laboratory setting, immunoglobulin G (IgG) sensitivity neared 100%; however, IgG sensitivity dramatically dropped (82%) in field testing. Possible factors include finger prick volume variability, hemolysis, cassette readability, and operator training.

通过 RPOC 侧流试验对 SARS-CoV-2 抗体进行血清学检测的毛细血管与静脉血的比较分析

对 278 名参与者进行了使用手指刺和静脉血的快速即时血清学测试的比较。在实验室环境中,免疫球蛋白 G (IgG) 敏感性接近 100%;然而,在现场测试中,IgG 的灵敏度急剧下降(82%)。可能的因素包括手指穿刺量的可变性、溶血、盒式磁带的可读性和操作员培训。
