Leukocytes

Eosinophils and monocytes are types of blood cells that belong to the class of leukocytes (white bodies). Their main task is to protect the body from microbes and malignant cells, removing foreign and dead particles. Therefore, it is so important to monitor the level of monocytes and eosinophils in the blood and in the child and in the adult, as increasing or decreasing their number can have serious causes.

The procedure for determining the level of monocytes and eosinophils

The determination of the level of eosinophils and monocytes in the blood is considered to be an important study capable of indicating serious infectious and viral pathological processes occurring in the body of a child or an adult. Based on the results of this analysis, the doctor appoints the patient further diagnosis and makes an approximate clinical picture of his current health status.

Taking blood from a child

To determine the parameters of monocytes and eosinophils in the blood in an adult or child, the doctor takes the analysis is exclusively from capillaries (from the finger or the heel), although in rare cases, the fence is also taken from the vein. However, before this procedure, the patient must be trained, consisting of the following stages:

  • Refusal to eat (except water) for 12 hours before the procedure (in the case of infants, blood is taken at least two hours after feeding).
  • Calming the nervous system. Before the procedure of taking blood, it is recommended not to be stressed, since an excited state can affect the results of the tests.
  • Correct completion of forms. Before the procedure begins, the patient must fill out a special form that indicates information about his body (age, weight, height, presence of chronic pathologies, etc.).
  • Refusal of exercise. If the patient is a professional athlete, or his work is associated with serious physical exertion, then for 1 - 2 days before the procedure, it is recommended that he refrain from the usual schedule and give the body relax.
.

Important! If the patient undergoes a course of drug treatment, then 2-3 days before taking blood for analysis, it should be temporarily interrupted. However, in the case of children before the abolition of medication, parents should always consult a doctor about this issue.

The norm of monocytes and eosinophils in the blood

To determine the normal number of monocytic and eosinophilic cells in a patient's blood, the doctor takes into account an important criterion - the age of the subject. Proceeding from this, the normal content of monocytes and eosinophils for each group of patients is as follows:

  • Not more than 10% of monocytes from the total number of leukocytes - for newborns;
  • No more than 14% of all leukocytes - for infants older than 5 days;
  • Not more than 12% - for children at the age of about 1 month;
  • Not more than 10% - for children from one year to five years;
  • Not more than 5% - for children from 5 to 15 years;
  • No more than 7% - for teenagers over 15 years.
Monocyte cell

Eosinophils in the blood of children under 13 years of age constitute, -7% of all leukocytes, later -5%.

If the results of tests show that the child has increased monocytes and eosinophils in the blood, then this condition is called monocytosis and eosinophilia. As practice shows, in adults this phenomenon occurs less often, and its causes are not always dangerous to health.

Causes of increased monocytes and eosinophils in the blood of a child

Increasing the level of monocytes and eosinophils in a child never arises simply because there can be serious reasons for this:

  • Autoimmune diseases (rheumatism, lupus erythematosus, etc.). With such pathologies, the body begins to intensively produce leukocytes, resulting in a significant increase in the level of monocytes and eosinophils.
  • Infectious mononucleosis. This pathology affects the liver, spleen and tonsils of the patient, resulting in a significant change in blood composition. With this phenomenon, not only monocytes and eosinophils, but also other cells related to leukocytes, increase.
  • Tuberculosis. At the first stages of development of this pathology, the level of leukocytes in the patient's blood drops, but after a few days after infection of the child's body with tuberculosis, the doctor will be able to observe the reverse picture.
  • Malaria. With such a pathology, as a rule, there is an increase in the number not only of monocytes and eosinophils, but of all other leukocytes in the blood.
  • Congenital syphilis. If the child has increased eosinophils and monocytes since birth, the reasons for such a deviation may be cover in congenital syphilis, which is transmitted from mother to child during pregnancy or childbirth.
  • Toxoplasma. These parasites, like any other similar organisms that have got into the child's body, can provoke significant changes in blood composition. As a result, the overall level of leukocytes in the patient will also be quite high.
  • Poisoning by toxic substances (phosphorus, chlorine or tetrachloroethane). All these substances have a very detrimental effect on neutrophils, which also form part of the blood, due to which the level of monocytes and eosinophils appreciably rises.
  • Oncological and malignant hematologic diseases (lymphoma, leukemia, etc.).
  • The level of eosinophils increases with parasitic diseases and helminthic invasions (giardiasis, opisthorchiasis, ascariasis, etc.). These cells are responsible for antiparasitic immunity. Another reason for the increase is allergies and diseases that are associated with them (bronchial asthma, Quincke's edema, atopic dermatitis, allergic rhinitis, etc.).
.

Important! If monocytes and eosinophils are increased in an adult, the reasons for this deviation may differ from those listed above. This is due, in the first place, to the fact that the children's immunity has not yet recovered, and many diseases occurring in the child's body are clearly manifested in the results of the analyzes (in particular on the KLA). It should be noted that with monocytosis, there may not be any concomitant symptoms in the child, and a rise in monocytes or eosinophils in the blood is detected only during a routine examination.
