The human body is a complex and multi-functional system in which everything works like clockwork.And one of its main features - the ability to protect themselves from various foreign agents that can damage the normal operation.A protective function in the body of white blood cells called leukocytes.
They have some of the most important properties, thanks to which this process is.Since they are directly involved in humoral and cellular immunity.And they have such a property as phagocytic activity.
But other than that white blood cells are actively involved in the metabolism of heparin and histamine.That is all of these properties and determine their properties are important to the organism, such as: antitoxic, antimicrobial, and other antibody.As you can see, their function is extremely important for the normal functioning of the body as a whole.Simply put, it is the white blood cells help us to deal with agents such as infections, bacteria and others.
The term "white blood cells" summarizes a few
All health authorities of certain white blood cells indicators included in routine blood test.
Naturally, with age, the number of leukocytes in the blood is gradually changing.So if the blood from the umbilical cord has 9,9-27,6 indicator, then after 24 hours from birth, this figure will 9,4-32,2.In one month - 9,2-13,8.This indicator of the level of white blood cells is relatively persist, somewhere up to 12 months.At this age, a child's rate of white blood cells will 6,0-17,5.These values are stored up to three years.The following age-gap 4 - 12 years.At this age, the number of white blood cells from a healthy child should be 6,1-11,4.In adolescence, these figures have normal - 5,5-10,0.Well, during the growing organism, it is up to 18 years - 9.5.In adults, the number of white blood cells is almost unchanged.Normal figures 4.0 * 10.9 / L - 9.0 * 10.9 / L.When the presence of inflammation in the body levels of white blood cells is growing rapidly.And the increase in these cells is called in medicine leukocytosis.A reduction - leukopenia.By the way, thanks to the level of white blood cells can be accurately identified some diseases.
most often in hospitals to determine white blood cell count is used leukocyte formula.As already mentioned above, that leucocytes are a mixture of various cells.That's exactly what percentage of the types of white blood cells to the total number of blood and called leukocyte formula.Identify it can only be in the lab.There is already a pre-identified rate of the number of these cells, which are guided and doctors in diagnosis.
presence and a detailed analysis of leukocyte helps more detail and deeply understand arisen pathological process in the body.This test is more accurate, since it is sometimes such that the total number of white blood cells are normal, and a more detailed analysis of them is that those cells more, and others less.
It's all happening for one simple reason - the fact that the increase in cells such as basophils, eosinophils and monocytes may simply have no impact in the general analysis of blood.But if you increase the number of neutrophils and lymphocytes - that these changes will lead to leukocytosis.The total percentage of all cells of the leukocyte may vary.Since these values are constantly fluctuating.However, in total this picture (hereinafter represented indicators adult and child in 2 weeks).Level myelocytes in the adult and the child, and the same is 0.5.Metamyelocytes are located within the boundaries of - 4.4 and 1.5 in the adult in the child.Neutrophils segmented adult - 40 and 70, the child - 25. The second category of neutrophils - stab.The rate of adults - from 1 to 5, the baby - 7.3.Such cells are lymphocytes within the borders - from 20 to 45, and in two weeks - 55. Next are the cells in which the percentage of extremely small.Again, an adult and a child.Since monocytes OK - 3 to 8 and 5. Eozinoily are within 1-5, the child figure 5.3.Basophils - from 0 to 1, at the two-week child - 0.5.Plasma cells - 0.25 and 0.5.
So in most cases, it is important to not only have a complete blood count, and the percentage of cells, the so-called leukocyte formula.It has several features.Thus, if the shift parameters in this formula is left - Ie is increasing the number of neutrophils, and can detect the appearance of such cells both myelocytes and metamyelocytes, it is 99% indicates that humans have purulent process, intoxication, inflammation, hemorrhage, as well as physical stress.
If the WBC has the right shift, ie a rejuvenation of the presence of neutrophils and promyelocytes and myeloblasts, such a condition is often observed in chronic leukemia, myelofibrosis, and metastases of tumors.
Another shift formula - to the right, with a decrease in band neutrophils and segmented increase.This condition is often preceded by anemia, kidney disease, and liver.author of the publication: Rostislav Belyakov
