What does it mean when lymphocytes are reactive?
Reactive lymphocytes are immune-stimulated lymphocytes with upregulated synthesis of inflammatory mediators, and/or immunoglobulins (antibodies), or both. Reactive lymphocytes in peripheral blood suggest active, systemic antigenic stimulation secondary to both infectious and noninfectious disorders.
What should lymphocyte percentage be?
Normal Results Lymphocytes: 20% to 40% Monocytes: 2% to 8%
Is 15% lymphocytes normal?
Normal ranges and levels The normal lymphocyte range in adults is between 1,000 and 4,800 lymphocytes in 1 microliter (µL) of blood. In children, the normal range is between 3,000 and 9,500 lymphocytes in 1 µL of blood. Unusually high or low lymphocyte counts can be a sign of disease.
Is 18% lymphocytes normal?
The normal range for lymphocytes is between 800 and 5000 (0.8-5.0) lymphocytes per mL of blood. A normal lymphocytes percentage is 18-45% of total white blood cells.
Are reactive lymphocytes normal?
Reactive lymphocytes are generally larger than normal, with increased amounts of basophilic cytoplasm and large nuclei containing finely granular chromatin.
Is 40% lymphocytes good?
Lymphocytes normally represent 20% to 40% of circulating white blood cells. When the percentage of lymphocytes exceeds 40%, it is recognized as relative lymphocytosis.
What is a high lymphocyte count?
A count significantly higher than 3,000 lymphocytes in a microliter of blood is generally considered to be lymphocytosis in adults. In children, the threshold for lymphocytosis varies with age. It can be as high as 9,000 lymphocytes per microliter.
What is a normal lymphocyte range?
Normal lymphocyte ranges depend on your age. For adults, normal lymphocyte count is between 1,000 and 4,800 lymphocytes per microliter of blood. For children, it’s between 3,000 and 9,500 lymphocytes per microliter of blood.
Is it normal to have reactive lymphocytes?
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).
