What tests do family members need to do for tuberculosis

Tuberculosis refers to a chronic infectious disease caused by infection with the bacterium tuberculosis. If the patient is diagnosed with tuberculosis, the family's examinations include general examinations, imaging tests, and laboratory tests.

1. General inspection

1. Blood routine: Because the onset of pulmonary tuberculosis will lead to an inflammatory reaction in the body, it is usually found that the white blood cell count will be elevated and the proportion of neutrophils will also increase when the blood routine examination is performed;

2. Urinalysis: Because the pathogen of tuberculosis can invade the kidneys, the glomerular filtration rate decreases, resulting in proteinuria.At this time, urine routine examination can determine whether there is hypoproteinemia and other conditions;

3. Routine stool: If the patient's condition is severe, there may also be intra-abdominal tuberculosis spread, which will affect intestinal function and lead to diarrhea and other symptoms. A routine stool test can be done to see if the number of white blood cells and red blood cells in the stool is normal.

2. Imaging examination

1. CT scan: CT scan is a commonly used method for diagnosing pulmonary tuberculosis, which mainly uses X-ray to scan a certain part of the body to form an image, which can clearly show the specific location of the lesion, and at the same time can also clarify the degree of the lesion, which has a certain helpful role in the diagnosis of the disease;

2. MRI examination: MRI examination is a non-invasive imaging technology, which mainly uses the principle of magnetic field to scan human tissues, and then converts the scan results into digital signals, and then forms images after computer processing, so as to understand whether there are abnormal changes in the lungs.

3. Laboratory examinations

1. Sputum smear acid-fast staining test: this examination is one of the important means to detect whether there is active pulmonary tuberculosis, and it is also the most widely used examination method in clinical practice, mainly under the guidance of a doctor to use a microscope to observe whether there are acid-fast bacteria in the sputum, if there is, it indicates that there may be pulmonary tuberculosis;

2. Tuberculosis antibody test: This test is mainly carried out by blood testing, if there are tuberculosis antibodies in the body, it indicates that you may have pulmonary tuberculosis.

Patients are advised to pay attention to a light diet in daily life and avoid eating spicy and stimulating foods, such as chili peppers, garlic, etc., so as not to aggravate the discomfort symptoms. In addition, patients also need to follow the doctor's instructions for regular follow-up examinations so that the treatment plan can be adjusted in time.
