How is it confirmed that tuberculosis is not diagnosed? Several tests have been done, but doctors ha

1. Long-term anti-inflammatory**, lesions are not absorbed, and pulmonary tuberculosis is considered.

2. If the PPD is greater than 15*15mm, it is considered to have active tuberculosis.

3. Sputum for acid-fast bacilli, if positive, can confirm the diagnosis of tuberculosis.

The left lower lung can also be tuberculosis.

Weakness, tiredness, laziness, reluctance to move.

Fever of hands and feet, lack of food and drink, low-grade fever during the day, flushed cheeks in the afternoon, and night sweats at night.

Fever, decreased physical strength, aching shoulders, irregular menstruation or amenorrhea in women.

Cough is frequent, but the phlegm is not much, sometimes with blood streaks in the sputum.

Massive hemoptysis, chest and back pain.

Hyperpyrexia. However, checking for phlegm is very important and reliable, so be sure to cough it up.

Tuberculosis is unlikely.

Find your local CDC online and ask which local tuberculosis hospital is. Go straight to the doctor.

Hello! What is the exact time for CT and chest x-ray? I can't see it clearly from the ** of the liquid you touched.

If it is a before and after comparison, the same examination is required for comparison, that is to say, if you do the CT examination before, it is better to have a CT film after the reexamination, otherwise it is impossible to accurately judge the changes in the lesions before and after. If the tuberculosis bacilli are found in the sputum, there is no problem in confirming tuberculosis, but if the tuberculosis bacilli are not detected, pulmonary tuberculosis cannot be ruled out, and sometimes it is difficult to detect the tuberculosis bacillus in the sputum because the orange grinding position of the lesion is not connected with the large bronchi. If the nature of the lesion must be determined, CT-guided lung puncture pathology may be done depending on the location of the lesion.

There are several ways to check for tuberculosis:

1. If there are no symptoms or physical examination, you can do a tuberculin test first.

2. If the tuberculin test is positive, further examination is required and a chest X-ray is taken. Or do a CT scan.

3. If there is a problem with the chest X-ray, you can do a tuberculosis antibody test again. Polymerase coupling reaction (PCR) can also be done where possible.

4. Patients with sputum can check whether there are acid-fast bacilli in the sputum.

5. Fiber bronchoscopy, lavage smear or culture to check for tuberculosis.

6. CT-guided percutaneous lung puncture for pathological examination of lesions.

The auxiliary tests for pulmonary tuberculosis are the above. The first four are the most commonly used.
