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.
对278名参与者进行了使用手指针刺血和静脉血的即时快速血清学检测比较。在实验室环境中，免疫球蛋白G（IgG）敏感性接近100%；然而，在现场检测中IgG敏感性大幅下降（82%）。可能的因素包括手指针刺血量的变异性、溶血、检测卡的可读性以及操作人员的培训。
