建立反相间接血凝法检测幽门螺杆菌抗原的方法。
It suggests HP antigen can take into blood stream and HP-RPHA can provide convenience for clinical diagnose of HP infection.
提示幽门螺杆菌抗原可侵入血流，血清抗原测定可为临床诊断幽门螺杆菌感染带来便利。
In this paper, an attempt to use the reverse passive haemagglutination assay (RPHA) to identify the predators of cotton aphid Aphis gossypii Glover was described.
本文介绍了应用反向间接血凝试验鉴定棉蚜的捕食性天敌，这种方法只需要少量试剂和简单的仪器并适于快速鉴定。
Conclusion: the RPHA has a high specificity and sensitivity. The method is simple and easy to observe the endpoint. It just needs a few antibody without special instruments.
结论：本r PHA法具有特异性强、敏感性高、方法简便、抗体用量少、无需特殊仪器、结果易观察等优点。
The results indicated that the positive rate of RPHA reached 87.5%(7/8), as compared with the positive rate of 50%(4/8) in agar gel precipitation(AGP), RPHA was more sensitive than AGP.
