Inflammation of the body from the blood routine, need to comprehensively analyze the white blood cells, neutrophils, monocytes, lymphocytes and so on. When there is inflammation in the body, the body’s immune system plays a defense mechanism, white blood cells gather around the lesion to phagocytose and kill inflammatory cells. Therefore, in the case of bacterial infections, the total number of white blood cells rises, and is often accompanied by an increase in neutrophils. In viral infections, the body’s immune system will be attacked, and at the same time will stimulate the body’s lymphocytes to fight against the virus, so in viral inflammation, the blood routine usually shows that the total number of leukocytes is normal or slightly decreased, and the proportion of lymphocytes is increased. Clinically, in addition to routine blood tests, other tests are often needed to identify the specific cause of the infection, such as calcitoninogen test and C-reactive protein. In some cases, imaging tests are also combined to look for foci of infection. In terms of treatment, routine blood tests and drug sensitivity tests are taken to comprehensively select sensitive antibiotics, which can lead to better anti-infection treatment. Whether the body inflammation need to find a doctor to see the routine blood report card, the doctor must also be based on the patient’s specific symptoms, clinical examination of the situation and other comprehensive analysis to determine the condition, must be under the guidance of the doctor’s treatment.
