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.
White Blood Cells
Basophilia (High Basophils)
Basophilia is when basophil count are elevated. It often signals underlying issues like MPNs, allergies, or inflammation.
Lymphopenia (Low Lymphocytes)
Lymphopenia is a low lymphocyte count, weakening immunity. It increases infection risk and flags underlying issues like cancer or severe illness.
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.

Lymphadenopathy
Lymphadenopathy explained: Learn about swollen lymph nodes, their common causes (infections, inflammation, cancer), key symptoms, diagnostic tests (blood work, biopsy), and available treatment options. Understand when swollen glands are a cause for concern.
Classic Hodgkin Lymphoma Treatment Strategies
Hodgkin lymphoma explained: treatment, stages, and what to expect. Your guide based on the latest NCCN recommendations.
Causes of Polycythemia
Polycythemia has high red blood cell count. Learn causes, symptoms (headache, fatigue), diagnosis (CBC, EPO), and treatment options.
Neutropenia
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)
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.
Causes of Eosinophilia (High Eosinophils)
High eosinophil count in blood. May indicate allergies, infections, or other conditions. Symptoms vary. Diagnosis via blood test.
