摘要
在深部真菌病发病的早期,患者的循环及体液内可出现较高浓度的真菌抗原成分,目前在部分疾病中已可利用该成分免疫测定作为特异诊断方法,对标本直接检验可采取直接镜检、乳胶凝集试验、酶联免疫试验(EIA)、荧光免疫测定法(FA)。如对新生隐球菌病中,其阳性率可高达99%以上,特异性为100%,如作动态检测可指导药物治疗及推断其预后。
In the early stage of deep mycosis,the component of the fungal antigen with high concentration can appear in the circulation and body fluid of the patients. Recently, the immune test of this component can be used as specific diagnostic method in some diseases. The direct microscopic examination, latex agglutination test, enzyme linked immunosorbent assay（EIA）,fluorescence immunoassay（FA） can be applied into the direct inspection of the specimens. As for the neoformans cryptococcus,the positive rate could be as high as 99%with 100%of the specificity. If for the dynamic detection, the prognosis wil be inferred.
