近年来,以抗体吸附红细胞所作血凝试验——反相被动红细胞凝集试验(R—PHA)用于鼠疫试验诊断,不但可检查活菌、死菌、F_1水溶性抗原,且可呈显高滴度阳性反应,敏感性、特异性较高,经济简便而快速。鼠疫R—PHA试验虽具有上述优点,但影响血清学反应之物理、化学、生物等因素亦不可忽视。野外试验所用材料多属强毒性质,尤其自毙鼠必须严密消毒后再进行检 In recent years, antibody agglutination of red blood cells for hemagglutination test - reverse phase passive red blood cell agglutination test (R-PHA) for the plague test diagnosis, not only can check live bacteria, dead bacteria, F_1 ​​water-soluble antigen, Positive degree of sensitivity, sensitivity, specificity, economy simple and fast. Although the plague R-PHA test has the above advantages, the factors affecting the serological reaction such as physics, chemistry and biology can not be ignored. Most of the materials used in field trials are virulent, especially since they must be sterilized and then tested
