A simple method for the collection of blood specimens on filter paper for serology of Helicobacter pylori was devised. Blood was freshly applied to small Whatman 3 mm filter paper and allowed to dry. Serological activity, as measured by reactivity to H pylori antigens (AMRAD, Australia), was retained after storage for one month at both room temperature and at 4 degrees C. This technique eliminates formal venepuncture, separation of sera, and arduous packaging of specimens to be sent to the laboratory.
设计了一种用于幽门螺杆菌血清学检测的滤纸血样采集简单方法。将新鲜血液滴加到Whatman 3毫米小滤纸上,使其干燥。通过对幽门螺杆菌抗原的反应性(澳大利亚AMRAD公司)测定的血清学活性,在室温及4℃下储存一个月后仍能保持。该技术无需进行正规静脉穿刺、血清分离以及将标本送往实验室的繁琐包装。
