How to judge bacterial infection/virus infection from the blood cell analyzer test sheet?

Now when we go to the hospital to see a doctor or have a physical examination, we will have a blood routine examination. As a common examination item, this examination is simple and easy to understand. We can judge whether virus infection or bacterial infection by interpreting the test sheet, mainly looking at white blood cells, neutrophils and lymphocytes. If the test results of white blood cells are not high, mainly lymph classification, and CRP is not high, it should be a virus infection, if white blood cells are high, neutrophil classification is the main, CRP is high, it should be a bacterial infection. Simply looking at the blood routine cannot determine whether it is a bacterial or viral infection. From the patient's laboratory tests, the white blood cell count is increased, and the neutrophil count is increased. Most of them are bacterial infections. Mixed infections are also more common. For simple viral infections, the white blood cell count may not increase.

If the patient has fever or other inflammatory manifestations, it generally indicates inflammation. If the blood test results are not high in white blood cells, neutrophils and C- reactive protein, virus infection will be considered. If our blood routine white blood cells are not high, neutrophils are not high, and C- reactive protein is normal, this can be diagnosed as a viral infection. The prerequisite is inflammation. The number of neutrophils and lymphocytes are within the normal range. At this time, if the patient has fever or runny nose, sneezing, or coughing, it can generally be considered that the possibility of virus infection is high.
From a professional point of view, bacterial infection is mainly caused by the obvious increase of neutrophils, while the number of lymphocytes is mainly increased when the virus is infected. Only by combining with the current symptoms of the patient can we infer what kind of infection is the main one. Blood routine can initially determine whether bacterial infection or viral infection, but it is clear which infection may require etiological examination. If the percentage of white blood cells and neutrophils is high, bacterial infection should be considered more.
As a regular examination item, blood routine looks at white blood cells, neutrophil percentage, lymphocyte percentage and C- reactive protein. If bacterial infection occurs, white blood cells, neutrophils, C- reactive protein, etc. will increase. If viral infection occurs, lymphocyte percentage will increase, while others are not high. Generally speaking, if it is bacterial infection, the vast majority will be reflected in neutrophils increased, crp increased. However, after the virus infection, some of them show an increase in the number of lymphocytes, white blood cells will not be too abnormal, and C- reactive protein will not increase. Therefore, according to the report, it looks like a virus infection. Professional medical personnel can be consulted for timely and effective symptomatic treatment.

Pay attention to the changes of various cell data in the blood
The number of various types of cells in the human body is within a constant range. The existence of these cells can ensure the normal growth and development of the body. The pathological changes of many diseases have a certain relationship with the sharp increase or decrease of the number of cells. Therefore, paying attention to the blood The changes in various cell data are an important prerequisite for disease prevention.
Blood cell analyzer, blood cells derived from bone marrow hematopoietic pluripotent stem cells. In addition to the ability to proliferate, stem cells can still migrate from the bone marrow hematopoietic tissue under certain circumstances, and form hematopoietic cell nodules as the blood flow reaches the extramedullary tissue, which is called colony forming unit. Each small node is composed of many cells of the same type, which are derived from the division of a stem cell.
