What does it mean when lymphocytes appear reactive?

Causes. Reactive lymphocytes are usually associated with viral illnesses, but they can also be present as a result of drug reactions (such as phenytoin), immunizations, radiation, and hormonal causes (such as stress and Addison’s disease), as well as some autoimmune disorders (such as rheumatoid arthritis).

What does relative lymphocytosis mean?

The definition of relative lymphocytosis is an increase in WBC of more than 40% in the presence of a normal absolute white cell count. In this review, we present the most common causes in adult patients, in addition to a general approach to diagnosis and management of frequently encountered etiologies.

Is Relative lymphocytosis serious?

You can have a higher than normal lymphocyte count but have few, if any, symptoms. It usually occurs after an illness and is harmless and temporary. But it might represent something more serious, such as a blood cancer or a chronic infection.

What does it mean to have relative lymphocytosis?

What Is Relative Lymphocytosis? Relative lymphocytosis is said to be present when the percentage of lymphocytes in blood is more than 40% but the absolute lymphocyte count is normal, that is, it does not exceed 4000/cu.mm of blood.

What are the symptoms of reactive lymphocytosis ( CBC )?

> Chronic lymphocytic leukemia (CLL), which is always accompanied by absolute and relative lymphocytosis, usually with high cell counts. Transformed, “stimulated” lymphocytes (“virocytes”) predominate in the CBC in the following diseases with reactive symptoms:

How is acute leukemia different from reactive lymphocytosis?

A slight left shift and elevated monocyte count are often found in the granulocyte series. Acute leukemia is often considered in the differential diagnosis in addition to other viral conditions, because the transformed lymphocytes can resemble the blasts found in leukemia.
