应用酶联免疫吸附试验（ＥＬＩＳＡ）方法检测了３６例皮肤结核病患者血清中抗ＰＰＤ一ＩｇＧ、ＩｇＭ抗体，并以１５例活动性肺结核及４０例健康献血者做对照，结果显示皮肤结核病组抗ＰＰＤ抗体阳性率为４４．４％，活动性肺结核为７３．３％，与健康组（２．５％）相差十分显著（Ｐ＜０．０１），而皮肤结核病组与肺结核组相差不显著，提示此方法可做为皮肤结核病诊断的辅助方法。
Enzyme linked immunosorbent assay (ELISA) method was used to detect anti-PPD-IgG and IgM antibodies in serum of 36 patients with cutaneous tuberculosis. Fifteen cases of active tuberculosis and 40 healthy donors were used as controls. The results showed that anti-PPD The positive rate of antibody was 44.4%, active tuberculosis was 73.3%, which was significantly different from that of healthy group (2.5%) (P <0.01), while there was no significant difference between tuberculous skin group and tuberculosis group This method can be used as an adjunct to the diagnosis of cutaneous tuberculosis.
