If a pregnant woman has symptoms such as coughing, coughing sputum, hot flashes, night sweats, or even blood in the sputum and loss of body weight, tuberculosis needs to be excluded. Because of the special nature of pregnant women, chest X-ray or chest CT examinations are not given to avoid the effect of radiation on the fetus. At this time, the following means can be used to further investigate whether the patient has tuberculosis: 1. Patients with sputum can be sputum checked several times for antacid bacilli and sputum tuberculosis culture, if positive, the diagnosis of tuberculosis can be considered, and if negative, tuberculosis cannot be completely ruled out. 2. T-cell tests for tuberculosis infection and blood tests can be given, and if the index is significantly higher than the normal value by 5-10 times, the patient also needs to be diagnosed with the possibility of tuberculosis. If the index is significantly higher than 5-10 times the normal value, the patient may be diagnosed with tuberculosis. 3. If necessary, complete chest MRI, bronchoscopy and other examinations according to the condition.
