When going to the hospital for routine physical examination and disease screening, one of the most common examination items is "blood routine"!
Many people do not understand this enough, thinking that they are obviously not a blood problem, and there is no need for a blood routine examination.
As everyone knows, many specific indicators in the blood routine are some of the more commonly used sensitive indicators, which have sensitive reactions to multiple pathological changes in the body, especially white blood cells, red blood cells, hemoglobin and platelets have great reference value.
Not only that, blood routine examination is also a common screening method for clinical observation of treatment effects, adjustment of medication, and disease recovery. Because of this, blood routines have become the most common clinical examination items in mainland China. It can screen and laterally assist in the diagnosis of multiple diseases, and can even be a key to malignant tumor exposure.
For example, the following indicators are abnormal, which may be a signal of malignancy and malignant tumors in the hematopoietic system, and need to be closely examined in the next step:
1. Red blood cell count
It refers to the number of red blood cells contained in a unit volume of blood, which is produced within the bone marrow, responsible for transporting oxygen and a part of carbon dioxide, and the change in the count is divided into two categories: physiological and pathological. Physiological changes are related to mental factors, pregnancy, and rapid development of infants and young children.
However, if there is a pathological increase in the red blood cell count, it may be a signal of the arrival of tumors and polycythemia vera. Abnormal reduction in erythrocyte production may be related to malignant changes in the hematopoietic system such as leukemia;
2. White blood cells
White blood cells are a kind of blood cells, and there are many types of white blood cells commonly found in the peripheral blood of the normal human body, such as neutrophils, eosinophils, lymphocytes and monocytes.
Overall, the role of white blood cells in the human body is immunity, which is part of the immune system. Physiologically elevated white blood cell counts usually occur after strenuous exercise and eating.
The pathological increase in the white blood cell count requires great vigilance, which may be related to serious diseases such as uremia, leukemia, and malignant tumors. Pathological abnormal reduction of white blood cells may be caused by aplastic anemia, infectious diseases, cirrhosis, malignancy leading to hypersplenism and other factors;
3. Platelets
Platelets are an important part of the coagulation system, when the blood vessel is traumatized and there are bleeding symptoms, it will be combined with the coagulation factor, through the action of clumps, the blood vessel injury bleeding site to react to the formation of coagulation.
The concept of platelets refers to the number of platelets in the blood per unit volume. When the number of platelet abnormalities is abnormal, it may be a signal of the arrival of bone marrow growth diseases, such as chronic myeloid leukemia, rejuvenation of red blood cell disease, primary thrombocytosis, etc.
Abnormal platelet reduction may be caused by acute leukemia, malignancy and hypersplenism.
Written at the end: All in all, the blood routine examination is not useless, it can screen out multiple problems inside the body, and can point out the next clear direction of the examination to the doctor.
At the same time, it can also expose the hidden problems of the body, and even become a breakthrough for malignant tumors. Therefore, when the doctor recommends that you have a blood routine examination, you should also actively listen to the doctor's arrangements so that you can screen out the hidden problems inside the body as soon as possible.
