Causes of Atypical Lymphocytes (Reactive Lymphocytes)

Atypical lymphocytes are activated immune cells, often seen in infections. Their unique look aids diagnosis, but distinguishing it from cancer is important.

Hypersensitivity Reactions: Causes and Mechanisms

Hypersensitivity is an exaggerated, undesirable immune response to an antigen, causing tissue damage. It encompasses four types: IgE-mediated (allergies), cytotoxic, immune complex, and delayed cell-mediated reactions.

Basophilia (High Basophils)

Basophilia is when basophil count are elevated. It often signals underlying issues like MPNs, allergies, or inflammation.

Hypereosinophilic Syndrome (HES)

White Blood Cells

Hypereosinophilic Syndrome (HES) is a rare disorder causing persistently high eosinophil levels, leading to organ damage and inflammation.

Leukemoid Reaction

White Blood Cells

Leukemoid reaction is a benign, reactive process with elevated LAP & no Philadelphia chromosome, unlike malignant CML.

Causes of Polycythemia

White Blood Cells

Polycythemia has high red blood cell count. Learn causes, symptoms (headache, fatigue), diagnosis (CBC, EPO), and treatment options.

Neutropenia

White Blood Cells

Neutropenia is a condition with a low count of neutrophils, key infection-fighting white blood cells. This increases susceptibility to various infections.

Infectious Mononucleosis (Mono)

White Blood Cells

Infectious mononucleosis (Mono), the “kissing disease,” is a common viral illness (EBV). Symptoms include sore throat, fever, fatigue, and swollen glands. Usually resolves on its own.
