Why the monocytes in a child are elevated or lowered?
Blood monocytes. Monocyte rate in children. Causes of the emergence of elevated monocytes. Why lowered monocytes in a child
When the general blood tests decrypt, then pay attention to the leukocyte formula, one of the parameters of which is the level of monocytes. If parents know about the components of this laboratory study, they can determine the state of their baby immediately upon receipt of the results of the analysis, even before consulting a doctor.
In turn, the results can show that the monocytes in the child are lowered or increased, that is, the presence of deviation from the norm. And the first, and the second testifies to the violations in the body.
Blood monocytes
Monocytes are blood cells belonging to the leukocyte group. They are the largest and more active, have a bit shifted from the center of the core, white. Produces their bone marrow. In the blood, they are present only a few days (2-3), and then distributed over the tissues. The most functional are young cells that are still present in biological fluid.
The main function is the absorption of dead fabrics and the fight against microbes, parasites, tumors.
They are responsible for the purity of blood, participate in its update.
Blood monocytes in children
These cells, like other varieties of leukocytes, are calculated by the percentage of eosinophils and neutrophilas. The normal level indicates a good absorption of dead cells, the absence of failures in the process of blood building, the absence of microbes, parasites and bacteria.
The norm of monocytes for children of different ages:
- Newborn – from 3 to 12%;
- Until two weeks old – 5-15;
- From 2 weeks to 1 year – 4-10;
- From 1 to 2 years – 3-10;
- From 2 to 12 years – 3-9;
- Older 12 years – 1-8.
It is worth noting that the increase in their amount may be relative and absolute. In the first case, their level is higher in relation to other varieties of leukocytes, but in relation to the body – this is the norm. In the second case, this means that their total amount in the body is more permissible.
Passing blood test, you need to perform some rules. It is necessary that the results do not get false. In definitely, the material fence is carried out on an empty stomach. Kid can drink only a small amount of water. On the eve, it is impossible to give him fatty food, and it is also recommended to limit active games, because the increase in blood monocytes in a small child can be provoked by physical activity.
In addition, if a child takes any drug drugs, then you need to report this to a doctor who assumes an analysis. The fact is that some pharmaceuticals can also affect the concentration of these cells.
Causes of the emergence of elevated monocytes in a child
When their number exceeds the norm, they talk about such a state as monocytosis. For the purpose of diagnosis, a slight increase in their level is not informative, since this state can be provoked by a rather large number of reasons, ranging from recent injury and ending with genetic disorders. And with absolute monocytosis in children, the results are more than informative, as they indicate the presence of serious pathology in the small body.
When a quantitative increase is more than 7 billion cells per 1 liter of blood, then the monocytosis is severe. At the same time, the percentage ratio with other varieties of leukocytes in this case no longer plays roles, although it almost always exceeds 8%. Exception are only kids to one year old age.
Causes may be hidden in the following pathologies:
- Infectious diseases of various origins, for example, viral, fungal (micaosis), protozoy, ricketersy, infectious endocarditis, etc.;
- Granulomatous – extrapy and pulmonary tuberculosis, syphilis, brucellosis, sarcoidosis, enteritis, ulcerative colitis;
- Diseases of the blood formation system – acute monoblastic and myeloblastic leukemia, chronic monocytarian and myelomocytic myelolomicosis, lymphogranulomatosis, mononucleosis;
- Collagenoses – rheumatoid arthritis, nodule polyarthritis, systemic red lupus;
- Inxication by phosphorus or tetrachloroethane.
Increased monocytes in the adult and the child arise in the case when the blood system does not cope with a large thread of malicious particles, so it actively produces protective cells. In rare cases, this occurs during the fallout of dairy teeth and the delicate of constant.
Relative monocytosis usually testifies not to existing pathologies, but about experienced diseases, injuries and stress. Should not be eliminated and such an option as an individual feature of the body, that is, the level growth is a normal state.
You can also distinguish several more reasons that provoke a minor increase in blood test: hereditary diseases, purulent infections, recently transferred oncological pathologies.
To make a diagnosis, the doctor must assign urine analysis, several other laboratory research and surveys.
Why low blood monocytes in a child
This indicator is diagnosed more often than the increase in their number. Doctors this condition is called monocytone. It is said about it when the number of cells falls below 0.04 · 10?/ L. The concentration drops sharply after stress, transferred injury, surgical intervention (operation), a long course of therapy by a number of medication preparations (. glucocorticosteroids). Monocytes can be lowered due to a pronounced infection flowing with a decrease in the level of neutrophils.
In severe cases, monocytopenia is the result of strong exhaustion of the body and extremely low immunity. The number of these cells falls after acute infections, for example, after abdominal typhoid or aplastic anemia, pancytopenia.
In conclusion, it should be noted that neither monocytopenia nor monocytosis require treatment. These states are the symptoms of any disease or its consequences. So doctors must first find out and eliminate the causes of these phenomena.
