Leukocytosis

Leukocytosis is a blood condition in which there is an increased level of white blood cells in the blood. The norm is considered to be between 4-9 units, and at elevated levels they already speak of leukocytosis. An increase in the number of leukocytes is a process of the body’s protective-adaptive reaction to various stimuli - intoxication, infection, injury, etc.

An increase in white blood cells can be caused by various reasons. They usually represent a response to viruses, bacteria and fungi entering the body. Leukocytes are white blood cells. The adult human body contains 4–9 x 10⁹ leukocytes. Blood consists of a liquid part - plasma and cells: red blood cells, platelets and leukocytes. During a bacterial infection, the number of leukocytes increases by 3-13 times. During viral infections, the number of leukocytes decreases compared to normal by almost 2 times. In the body there are the main cells of the immune response - lymphocytes, plasma cells, granulocytes. Based on the results of studying morphology, granular or granulocytic neutrophils, monocytes and basophils are distinguished. Each variety is responsible for a specific function. The following types of granulocytes are distinguished: | | | |----------|-------| | Polymorphonuclear:
- neutrophilic
- stab | Agranulocytes^Note
| | Agranulocytes:
− Basophils
− Eosinophils
| Monocytoids| | Monocore
