[audio]http://sound.yywz123.com/tingbbs/voa/voa20110823.mp3[/audio]The World Health Organization is urging health officials to ban commonly-available blood tests for tuberculosis. W.H.O. officials made the call after two studies found that results from a commonly used test are undependable and misleading.
世界卫生组织督促卫生官员禁止目前普遍采用的血液检测方法诊断肺结核病。两项研究发现目前普遍采用的测试不可信且可能误诊，世界卫生组织做出这个决定。
The blood tests are low-cost and produce fast results. They are widely used in developing countries, especially India. The Indian government says the country has more than two million new cases of TB a year.
血液检测成本低且检测结果出来得快。普遍用于发展中国家，特别是印度。据印度政府统计，每年全国有200多万的肺结核新病例出现。
