A new latex particle agglutination test for direct detection of Haemophilus influenzae type b polyribose phosphate antigen in serum, cerebrospinal fluid, or urine was evaluated from studies at four clinical centers. Although use of a serum buffer significantly reduced inconclusive agglutination of the latex particles, the retesting of serum samples, after heat inactivation and dilution, resolved all serum samples, with one exception, as reactive or nonreactive for the presence of the polyribose phosphate antigen. A clinical accuracy of 100% was obtained for the latex particle agglutination method in respect to its capability for detection of polyribose phosphate antigen in all patients with confirmed infection by H. influenzae type b.
通过四个临床中心的研究,对一种用于直接检测血清、脑脊液或尿液中b型流感嗜血杆菌多聚核糖磷酸抗原的新型乳胶颗粒凝集试验进行了评估。尽管使用血清缓冲液显著减少了乳胶颗粒的不确定凝集,但对热灭活和稀释后的血清样本进行重新检测后,除一个例外,所有血清样本均确定为对多聚核糖磷酸抗原呈反应性或无反应性。对于所有确诊感染b型流感嗜血杆菌的患者,乳胶颗粒凝集法检测多聚核糖磷酸抗原的临床准确率达到了100%。
