1. Blood cell structure

Blood cells are the visible components in the blood, including red blood cells, white blood cells, and platelets. Red blood cells are responsible for transporting oxygen throughout the body. White blood cells are part of the immune system, which play a role in defending the body by detecting and destroying disease-causing "foreign objects".
There are 5 different types of white blood cells, each with its own function. Each type of white blood cell is present in the blood in certain amounts. Each different inflammatory condition activates certain types of white blood cells, causing them to increase in number compared to normal.
Platelets are very small cell fragments that participate in the hemostasis function by forming blood clots that seal wounds in the blood vessel walls. In addition, platelets also make the vessel walls soft and supple thanks to the function of platelets to "rejuvenate" endothelial cells.

2. What is a blood cell count test?

Blood cell count test (Peripheral blood cell count) is a survey of blood cell types in terms of the number of red blood cells, white blood cells and platelets, the percentage and absolute number of each type of white blood cell. demand, helping to detect abnormal increases or decreases.
For the red blood cell line, in addition to the red blood cell count, the peripheral blood cell total analysis test also has the hematocrit index, the amount of hemoglobin . In addition, the current cell counter systems also provide parameters about the shape and size of red blood cells, platelets, the number of abnormal white blood cells...
Blood cell test The periphery will provide early evidence of changes in the patient's health status and disease progression. Abnormal tests can have many different causes. Then, additional tests must be performed to diagnose the cause of the disease.
To perform a complete peripheral blood cytology test alone (without doing other tests), you can eat and drink normally before taking the test sample.

The nurse/technician will insert a needle into your vein, take about 1-2ml of blood, store it in a test tube with anticoagulant. Then the blood will be put into the machine, count the number and describe the size of the cells by the automatic machine. The more modern equipment and machinery will give more accurate results, more parameters with shorter time.
