结核菌素试验(以下简称“结素试验”)是一种最简单、最准确和最常用的检测结核感染的方法。习惯上认为在注射结素后48～72小时观察皮试结果才是正确的和准确的,从而,不得不延长流行病学调查时间,有时给工作带来一定影响。为此,我们于84年7月对结素试验24小时观察反应结果进行了初步探讨。 Tuberculin test (hereinafter referred to as “tuberculin test”) is one of the simplest, most accurate and most commonly used method of detecting tuberculosis infection. It is customary to observe that the skin test results are correct and accurate 48 to 72 hours after injection, which in turn has to prolong the time of the epidemiological investigation and sometimes have a certain impact on the work. To this end, we conducted a preliminary study on the 24-hour observation of the response test in July84.
