What's the matter with high monocyte count in blood routine test

Routine blood tests are very important for the diagnosis of diseases. Doctors can intuitively see where the health problems lie from the routine blood test report. Many serious diseases can be ruled out based on the blood routine report, and symptomatic medication can be used to prevent the abuse of antibiotics. However, not everyone can understand the routine blood test report. In fact, through this small routine blood test report, we can easily judge our physical condition, understand the development of the disease, and provide targeted care. However, not many of us can understand the routine blood test report, and the outpatient doctors do not have time to explain it to us in detail. So let’s talk in detail about how to understand the blood routine test report.

1. Let’s first look at the first item in the test report, CRP. CRP stands for C-reactive protein. Many large hospitals conduct micro-blood CRP tests. This is an initial screening test that can determine whether the child has a bacterial infection. White blood cells can also determine whether a child has a bacterial infection, but CRP is more sensitive and appears earlier than white blood cells. At the same time, CRP is also an indicator of the systemic response of the disease. If the value is several times higher than the normal value, it often indicates that multiple organs of the patient's body are damaged. In addition, CRP is also related to some serious diseases, such as infectious mononucleosis, Kawasaki disease, rheumatic fever, etc.

2. Look at the number of white blood cells (WBC). Many parents only check whether the white blood cell count is high when they get the test report. Generally speaking, if the white blood cell count is greater than 10,000, it indicates that the child has a bacterial infection and needs to use antibiotics. The higher the white blood cell count, the more virulent the bacteria or the greater the number of bacteria. But sometimes a particularly high white blood cell count does not necessarily mean a bacterial infection, as white blood cells also contain lymphocytes and neutrophils. If a child has infectious mononucleosis, the number of lymphocytes in his body will be particularly high, so the total white blood cell count will also be particularly high, possibly reaching 20,000 or even 30,000. In fact, most of them are lymphocytes, not neutrophils.

3. Look at the percentage of neutrophils . The higher the value, the more the disease is still developing and may worsen further. Neutrophils mainly target bacteria. When a child's body is infected with bacteria, the number of neutrophils will increase to kill the bacteria. If the neutrophil percentage decreases, the lymphocyte percentage will increase accordingly, indicating that the child may have a viral infection.

4. Look at the absolute value of neutrophils . If it is lower than the normal value, it means there is a viral infection. The lower the absolute value of neutrophils, the more severe the viral infection. If it is higher than normal, it indicates a bacterial infection. For some children, the total white blood cell count in their bodies is not very high, but the absolute value of neutrophils is very high, which indicates that the child's fever will become more and more severe.

Look at the absolute value of lymphocytes and the percentage of lymphocytes. What do lymphocytes do? Lymphocytes mainly fight viruses by secreting antibodies. If these two values ​​are higher than normal, it means that the child may have a viral infection.

Routine blood tests are important as they provide a reliable basis for determining the severity and changes of a child's illness.
