Elevated lymphocytes: who is to blame and what to do?

The human blood consists of many importanteach of which performs its function and maintains human health. Lymphocytes are blood cells that are an integral part of the immune system and play a crucial role in the body's resistance to various diseases. They are responsible for cellular and humoral immunity, for the production of antibodies and immunoglobulins, as well as for the interaction of certain cells that provide local immunity.

Lymphocytes have their own classification.Isolate NK-lymphocytes, T-lymphocytes and B-lymphocytes. Each species reacts to a certain type of danger and performs certain functions. As soon as the aggressor invades an organism that provokes a disease, or if an inflammatory process starts, and if pathologically altered or cancerous cells appear somewhere, it immediately reacts with the production of lymphocytes.

Повышенные лимфоциты свидетельствуют о том, что the protective mechanisms of the immune system have started, which, in turn, is a sign of certain health problems. This condition, when a clinical blood test reveals an excess of the norm of lymphocytes, is called lymphocytosis.

It should be noted that elevated lymphocytes canbe a consequence of reactive or malignant lymphocytosis. What is reactive lymphocytosis, is evident from the name. This increase in the number of lymphocytes, provoked by a reaction to the penetration of an aggressor. This is how the immune system struggles with diseases, and it can be compared with the mobilization of troops, and lymphocytes - with those same troops.

Most often, elevated lymphocytes in the blood arereaction to viral infections (influenza, ARVI, cytomegalovirus, rubella, chicken pox, etc.), infectious diseases of non-viral nature (syphilis, tuberculosis, diphtheria), allergic reactions and hormonal disruptions. To determine exactly what reason elevated lymphocytes were found, the doctor needs to learn about other possible symptoms that are troubling the patient.

Malignant lymphocytosis is an excess of the normleukocytes on the background of the development of leukemia. It is often accompanied by an increase in lymph nodes, liver or spleen, but you should not be alarmed by finding elevated lymphocytes and enlarged lymph nodes. Only a specialist can evaluate the symptoms and draw any conclusions.

Norms of white blood cells in the blood laboratorythey usually write on their forms, however, the mistake of almost all of them lies in the fact that they do not decipher the age norms. This is very important, because in the course of human life this indicator changes. For an adult, the level of 35-40% of lymphocytes is normal, for a newborn 15-35%, for children from 1 to 2 years old - from 35% to 60%. Therefore, if parents have found elevated lymphocytes in a child, first you need to make sure that we are talking about the correctly indicated age norms. If it is really about exceeding the norm, only the doctor should decide how to act. It is impossible to let it flow or ignore elevated lymphocytes.
