The fluorescent treponemal antibody absorption (FTA-ABS) double-staining procedure was reproducible, comparable to the conventional test, and easy to read. We recommend the use of the FTA-ABS double-staining procedure for microscopes with incident illumination, the 100 x/1.30 oil achromatic objective and the 6.3 x ocular to obtain optimal fluorescence, and the KP560 as a barrier filter to exclude rhodamine emission when fluorescein fluorescence is read. With this system, errors related to poor focusing or failure to visualise treponemes on all smears should be eliminated.
荧光密螺旋体抗体吸收(FTA-ABS)双重染色程序具有可重复性,与传统检测方法相当,且易于判读。我们建议,对于配备落射照明、100x/1.30油浸消色差物镜和6.3x目镜的显微镜,使用FTA-ABS双重染色程序以获得最佳荧光效果,并使用KP560作为阻挡滤光片,在读取荧光素荧光时排除罗丹明发射光。使用该系统,应可消除因聚焦不佳或未能在所有涂片上观察到密螺旋体而导致的误差。
