What does the three-category blood test check?

Physical examination is a very important matter in modern life. It can detect health problems in time and study the most appropriate treatment method based on the examination results. Among them, routine blood test is the most popular examination method, and it is very effective and can detect problems in the body in time. Let’s take a look at what the three categories of blood routine tests check. I hope everyone can understand.

In human blood, there are three types of cells with different functions: red blood cells, white blood cells and platelets. White blood cells are one of the important indicators. From the white blood cell test results, the doctor can determine the type of infection and how advanced the condition is.

At present, hospitals at all levels usually use two blood testing methods: three-category blood test and five-category blood test.

A routine blood test is a routine examination. When you go to the hospital, you will usually be asked to have a routine blood test to check your basic physical condition. If you have trouble sleeping, they should check your red blood cells, hemoglobin, and white blood cells. If these values ​​are low, you will experience drowsiness.

What is the three-level classification of blood routine test? During the test, the white blood cells in the blood are divided into three types: small cells (lymphocytes), intermediate cells (other white blood cells) and large cells (neutrophils).

The five-category classification of routine blood test is a test in which the white blood cells in the blood are divided into five categories: eosinophils, alkaliphils, neutrophils, monocytes and lymphocytes.

Generally speaking, whether it is a three-category or a five-category blood test, there is not much difference in the red blood cell and platelet testing instruments. It’s just that the price of three-category inspection is advantageous and is much lower than that of five-category inspection.

At present, the routine blood tests performed in hospitals are mainly three-category and five-category classification, which is for the classification of white blood cells. The three-category instrument can roughly divide white blood cells into three categories: large cells (neutrophils), intermediate cells (other white blood cells), and small cells (lymphocytes). The five-category instrument can divide white blood cells into five categories: neutrophils, lymphocytes, eosinophils, alkaliphils, and monocytes. There is little difference between the various instruments in the red blood cell and platelet systems. If abnormal or immature cells are found, manual smear microscopy and classification are used. There is a difference in price when doing a three-category or five-category examination in the hospital, and the five-category is more expensive.
