Nowadays, when you go to the hospital for medical examination, the most commonly used test is blood routine, even if you have a cold, you will use this test method, and when you see the dense data on the blood routine test report, many people will have questions: what can it show?
Today, let's take a look at the blood routine report and teach you to understand the problem of blood disclosure.
3 indicators teach you to understand the blood routine report!
1. Red blood cell count and hemoglobin
One of the main functions of human blood is to transport oxygen and nutrients, and its carrier is red blood cells, and hemoglobin is a special protein that transports oxygen in red blood cells.
Under normal circumstances, the value of red blood cells in the human body is: 4.0-5.0×1012 cells/liter in men; Females 3.5-5.0×1012 pcs/l. The normal value of hemoglobin is 120~165g/L for men; 110~150g/L for women, if the data shown on the blood routine test report is lower than the standard value, it indicates that the patient has anemia problem.
2. White blood cell count
The white blood cells in the human body do not specifically refer to one cell population, but the synthesis of a variety of cells, which can be divided into neutrophils, eosinophils and basophils, etc., and their role is mainly to resist viruses and germs.
Under normal circumstances, the total number of white blood cells in the human body is 4.0-1.0×109 per liter, if it is higher than this value, it is likely that the body will have signs of inflammation, but the specific cause of infection can be determined by the values of neutrophils, eosinophils, and basophils.
3. Platelet count
The main function of platelets is to stop bleeding, under normal circumstances, the normal value of platelets in the human body is 125-320×109 / liter, if the platelet count < 50×109 / liter, the patient's mild injury will cause skin and mucosal purpura, and postoperative bleeding will cause bleeding problems;
If it is less than 20×109 cells/liter, spontaneous bleeding will occur and prophylactic blood transfusion is required, which can be shown on the blood test report.
Precautions for routine blood test:
1. Before the inspection, the diet should be light
If the diet before the test is too oily, it will affect the blood composition and thus affect the test results, and alcohol abuse and high-protein diet should be avoided.
In addition, you should avoid drinking too much water before the blood test, as this will cause an increase in blood volume, which will cause red blood cells to be diluted and the red blood cell count to decrease.
2. Attention should be paid to fasting during special examinations
During the daily physical examination, most people will be told to fasting examination, but not all blood routine tests need to be fasting, when fasting is required, the examinee should be fasting for 8-12 hours, during which time should be fasted and watered, the best blood draw time is 7:30-8:30, should not exceed 10:00, otherwise the test results will be affected.
3. Other precautions
Blood collection should be relaxed, which helps to reduce pain and facilitate the normal progress of blood collection. After the blood draw, the person to be tested should choose to sit still for a few minutes, press the needle hole to stop the bleeding, and do not rub it to avoid causing subcutaneous hematoma.
In addition, if you feel unwell after blood drawing, such as dizziness, dizziness, and fatigue, you can choose to lie down and drink sugar water to solve it, and those with severe symptoms should seek help from medical personnel.
As we have learned from the above, the red blood cell hemoglobin count, white blood cell count and platelet count in the blood routine report report can usually show a lot of information, which can provide clinical evidence for the patient's related diseases, and based on these data, the blood can be understood.
