The Mantoux test was performed on 75 Saudi and Yemeni patients with pulmonary tuberculosis using 2TU of PPD-RT23; 82.7% of these patients had a positive skin test. It was also noted that, contrary to findings in the West, old age does not seem to affect the Mantoux reaction adversely. 9 patients had a non-significant reaction and using the 3-step 'boosting', 8 of the 9 (88.9%) non-reactors converted to positive. Despite the low number of patients included in our study, we recommend 3-step 'boosting' when doing tuberculin skin testing in Third World Countries in order to bring out the true tuberculin 'reactors'.
对75名沙特和也门肺结核患者使用2个结核菌素单位的PPD-RT23进行了结核菌素试验；这些患者中有82.7%的皮肤试验呈阳性。还注意到，与西方的研究结果相反，高龄似乎并不会对结核菌素试验反应产生不利影响。9名患者的反应不显著，采用三步“增强法”后，9名无反应者中有8名（88.9%）转为阳性。尽管我们研究纳入的患者数量较少，但我们建议在第三世界国家进行结核菌素皮肤试验时采用三步“增强法”，以找出真正的结核菌素“反应者”。
