摘要
目的 探讨学生中预防服药对象结素反应强度的界定标准。方法 学生统一作结核菌素试验，72h观察反应，以硬结的最大直径mm数作记录。结果 共筛查学生53897名，结素反应0～4mm35331人，占65．6％；5～9mm 7892人，占14．6％；10～14mm 6744人，占12．5％；15～19mm2746人，占5．1％；≥20mm或不足20mm但有水泡溃疡者1184人，占2．2％。经统计学处理，各年龄组之间阳性率均有非常显著性差异。结论 学生中结索反应≥15mm者多为自然感染所致，可以作为药物预防对象的界定标准。
Objective To explore the cut-off point for tuberculosis diagnosis criterion by identifying magnitude of reaction to tuberculin among students. Methods Students were asked to take tuberculin test and their 72 h reaction to the test was observed. The maximum diameter mm for each participant was recorded. Results Among the total of 53897 students, there were 35331 （65.6%） having reaction of 0 to 14mm; 7892 （14. 6% ） of 5 -9 mm; 6744 （ 12.5% ） with 10 - 14 mm; 2746 （5.1%） of 15 - 19mm. 1184 students （2.2%） had diameter larger than 20 mm or developed some bubble or ulcer if under 20mm. Conclusion The reaction larger than 15mm is largely due to national infection, which may be used as the cut-off point for prevention purpose.
