肺结核皮试后的反映，疑问。。

Question

三天前做的肺结核皮试，现在的反应时做皮试的部位肿得像蚊子叮后的疙瘩，但是大小跟枣差不多，上面还长了好多小水泡，这种反映说明什么？
谢谢了

Answer 1

肺结核皮试叫PPD试验。在注射后48～72小时，根据前臂注射部位皮肤的硬结直径判定机体的反应程度：皮肤无反应者属于阴性结果，硬结直径小于5毫米者为可疑，硬结直径在5～9毫米者为弱阳性，硬结直径在10～19毫米者为中度阳性反应，硬结直径大于20毫米者为强阳性反应。如果除硬结外，皮肤表面还出现水疱、坏死或淋巴管炎者，为极强阳性反应。

根据你的描述，你的试验结果是强阳性，表示体内有活动性结核病。一定要去医院就诊。

Answer 2

枣很大，大于15mm了，加上水疱，基本可以肯定是结核活动。可以直接去医院了。不用等时间了。

Answer 3

强阳性，您身体有结核病灶，而且处于活动期。

Answer 4

OT试验阳性，你感染了。需要马上治疗。

Answer 5

我昨天刚打了，明天早上去看结果，现在状况是中间一个直径3mm比较红的点，没有明显的突起，边上有一圈淡淡的红晕，量一下红晕直径大约9mm。我找了一些英文医学资料，如果你有水泡可能是阳性反应，"if blisters are present (vesiculation), the test is also considered positive." 去医院让医生检查检查吧，我的doc跟我说一般硬块直径大于5mm就要仔细看看情况（当然超过5mm也不说明是阳性)，有水泡更值得怀疑了。还有，阳性结果并不一定说明你有什么毛病，你可能有疫苗或者之前得过，做个胸透确认一下吧。

英文资料如下：
The basis of the reading of the skin test is the presence or absence and the amount of induration (localized swelling). The diameter of the induration should be measured transversely (i.e. perpendicular) to the long axis of the forearm and recorded in millimeters. The area of induration (palpable, raised, hardened area) around the site of injection is the reaction to tuberculin. Again, redness is not measured. A tuberculin reaction is classified as positive based on the diameter of the induration in conjunction with certain patient-specific risk factors. In a healthy person who is not immunocompromised, induration greater than or equal to 15mm is considered a positive skin test. If blisters are present (vesiculation), the test is also considered positive. In a person with underlying kidney disease, diabetes, or a healthcare worker, 10mm of induration is considered a positive skin test. 5 mm is considered a positive skin test result for patients who are immunocompromised, such as with rheumatoid arthritis patients and Crohn's disease patients. Induration of less than 2mm, without blistering, is considered a negative skin test.

表示呈阳性反应，应该是肺结核，建议再拍片检查一下。
