Laboratory assay overview
Increased understanding of immunodeficiency syndrome and AIDS have identified the importance of absolute lymphocyte count in addition to the specific cell type such as CD4 lymphocytes. In pediatric ages up to 14 years old, acute infectious lymphocytosis is a clinical disorder, suspected to be of enterovirus-Coxsackie A subgroup that may have upper respiratory symptoms, fever, diarrhea and abdominal pain or a totally asymptomatic clinical course. Other conditions with absolute lymphocytosis are B. pertussis infection and lymphocytic leukemoid reaction. The most commonly known lymphocytosis with atypical morphology is due to cytomegalovirus and infectious mononucleosis. The malignant forms of absolute lymphocytosis are mostly due to lymphoproliferative disorders.
