应用间接血凝试验(IHA)诊断肺螨病的实验观察

EXPERIMENTAL OBSERVATION ON DIAGNOSIS OF PULMONARY ACARUSIS WITH IHA

本文采用醛化绵羊红细胞以1:800粉尘螨抗原制成致敏血球进行间接血凝试验(IHA)。37例患者阳性滴度的几何均值为84.82,最大滴度1:256,阳性率86.49％,与对照组比较有显著差异。结果认为间接血凝试验可用于肺螨病的辅助诊断,方法敏感方便,具有一定的应用价值。

Indirect hemoagglutination assay ( IHA ) was given to examine the serum of patients with pulmonary acariasis by sensitive sheep red blood cells absorbed by Dermatophagoides farinae extract as antigen. The geometric average value of positive titre in 37 cases was 84.82; while the maxmum titre was 1:256, and the positive rate was 86.49% which was appreciably different from that of the negative control. The results showed that IHA could be used as an auxiliary diagnosis.
