The following indicators may be abnormal in the blood count of TB patients: i. Total white blood cell count, which tends to rise during the active phase of TB, especially when fever is present, must be alert to TB being active or accompanied by other lung infections. Second, it is easy to have anemia and decreased hemoglobin, which is called decreased hematocrit, due to tuberculosis. Tuberculosis is a chronic wasting disease, which easily leads to general malnutrition and symptoms of anemia and low protein. Third, TB patients are prone to significantly higher platelet count in blood routine, caused by TB resulting in wasting of the body, increased blood viscosity and secondary increase in platelets, which can easily cause blood clots. Therefore, the basic judgment of three indicators of pulmonary tuberculosis can laterally assess the treatment of pulmonary tuberculosis and systemic condition, so as to actively give standardized anti-tuberculosis treatment, correct malnutrition and anemia, and appropriately use blood-stasis-activating drugs to avoid the occurrence of blood clots.
