White Blood Cells

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.

Eosinophils

Eosinophils

Eosinophils are white blood cells that play a crucial role in the immune system. They are involved in fighting parasites, allergic reactions, and tissue repair. Elevated eosinophil counts can be a sign of various conditions, including parasitic infections and allergic diseases.

Monocytes

Monocytes

Monocytes are large white blood cells that play a crucial role in the immune system. They are responsible for phagocytosis, antigen presentation, and inflammation. Elevated or decreased monocyte counts can be indicative of various diseases.

Lymphocytes

Lymphocytes

Lymphocytes are essential white blood cells that help protect the body from infections and diseases. They come in three main types: B cells, T cells, and NK cells, each with its unique role in the immune system.

Neutrophils

Neutrophils

Neutrophils are white blood cells crucial for fighting infections. They engulf and kill bacteria through phagocytosis. Learn about neutrophilia, neutropenia, and their role in immune health.

Non-Hodgkin Lymphoma (NHL)

Non-Hodgkin Lymphoma (NHL)

Non-Hodgkin lymphoma (NHL) is a diverse group of cancers of the lymphatic system. Unlike Hodgkin lymphoma, NHL encompasses various subtypes based on lymphocyte type (B-cell or T-cell) and growth rate (slow-growing or aggressive).
