How to quickly understand the blood test sheet?

When you come to the hospital for examination, you will find that almost every patient will do a project called five-cell classification of blood cells. They will often feel confused about this project. When they see some arrows go up and some arrows go down, they will be particularly worried about whether they got it. What is seriously ill?

So how to quickly understand the blood routine test list? First, blood is composed of plasma and blood cells. Blood cells include white blood cells, red blood cells, and platelets. It is much easier to understand the role of these three cells in the body and the symptoms prompted by their numbers.

1. White blood cells

The white blood cells in the human body mainly play a role in immunity, so changes in white blood cell count often mean changes in the immune system.

White blood cells are divided into neutrophils, basophils, eosinophils, lymphocytes and monocytes.

1. The increase of neutrophils is bacterial infection and inflammation;

2. Increased lymphocytes are viral infections;

3. The increase of monocytes is caused by certain infections or certain blood diseases.

It should be noted that many people get the test sheet first to see whether the number of white blood cells is large or not. Generally speaking, if the number of white blood cells is greater than 10×109/L, it may indicate that there is a bacterial infection. But sometimes it is extremely high, and it may not necessarily be a bacterial infection. White blood cells contain lymphocytes and neutrophils, some people may be blood diseases. Neutrophils are mainly for bacteria. If the percentage of neutrophils decreases, the percentage of lymphocytes will increase accordingly, indicating that it may be a viral infection.

Second, red blood cells

1. If the red blood cells of the human body are increased, it can be seen in polycythemia vera, pulmonary heart disease, emphysema, high altitude hypoxia, etc.;

2. Red blood cell value reduction is more common in various anemia, blood thinning and other symptoms.

3. Platelets

We found that platelets are very small under the microscope, but it has a great effect. Too many or too few platelets can cause abnormal blood coagulation. When there are too few platelets, it is necessary to pay attention to whether he is suffering from hematopoietic system diseases, or spleen hyperfunction, or the increase of platelets after taking some drugs often prompts bone marrow disease.

The above are the main items on the blood routine test form. If you understand these, then when we get the test form, we will not be confused.
