Lymphocytes are a constituent of blood.They take part in protecting the body from the effects of viruses and bacteria. The fact is that lymphocytes have a unique ability to determine the presence of a foreign protein.
Sometimes it happens that in a blood testan increased content of this element is found. If lymphocytes are increased, it is a signal that pathogens are present in the body. But the cause of an elevated level is not always infectious diseases. Often, everything turns out to be more serious. Sometimes elevated lymphocytes in an adult can be detected in the case of chronic lymphocytic leukemia.
Often people have a question, and whatthe number of these elements in the blood is normal? First, you need to take into account the fact that their level undergoes significant changes in the process of human life. For example, if the lymphocytes in children under the age of 4 are 45-65%, then by 5-7 years, the norm is already 30-35%. For an adult, a level of 25-40% is considered normal.
Abnormalities can be a signal of a serious illness
When a doctor examines a general blood testthe patient sees that the patient has significantly increased the level of lymphocytes, the first task that should be decided by the specialist is to find out what causes these changes, whether they are reactive, whether this indicates that the increase is the body's response to external influence or whether it is malignant changes. In the medical literature, there are two types of lymphocytosis: reactive and malignant.
In the first case, increased lymphocytes in an adultsignal about the ingress of viruses or pathogens into the body that triggered the onset of a disease. As a rule, after excluding the pathogenic effect of the virus and complete recovery within 2-3 months, the amount of this element in the blood comes back to normal.
In the second case, when it comes tomalignant lymphocytosis, the situation does not look so harmless, as this organism signals the beginning of the process of an independent lymphoproliferative disease, the most dangerous form of which can be acute or chronic leukemia.
From these examples it is clear that elevatedlymphocytes in an adult or child can become a signal of the presence in the body of both a minor, non-life-threatening infection, and a very serious disease. The main problem is that, according to a general blood test, even an experienced specialist is not able to determine with 100% confidence, for what reason, there are increased lymphocytes in an adult: whether it is a conventional reactive lymphocytosis or whether he is dealing with a malignant form of the disorder.
In order for the doctor to determine what caused thehe needs to make the patient an appointment for additional, more complex and expensive tests that will be able to determine the presence of chromosomal abnormalities in the nuclei, if any, and in the early stages begin to fight a serious disease that threatens the patient's life.
