Polycythemia has high red blood cell count. Learn causes, symptoms (headache, fatigue), diagnosis (CBC, EPO), and treatment options.
White Blood Cells
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.
Monocytosis (High Monocytes)
Monocytosis: Elevated monocytes signal underlying health issues. Learn causes (infections, cancers), symptoms, diagnosis, and management.
Lymphocytosis (High Lymphocytes)
Lymphocytosis: High lymphocyte count. It can be a harmless immune response or signal serious conditions like leukemia.
Lymphopenia or Low Lymphocytes
Lymphopenia is a low lymphocyte count, weakening immunity. It increases infection risk and flags underlying issues like cancer or severe illness.
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 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 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 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.
Hairy Cell Leukemia (HCL)
Hairy cell leukemia (HCL) is a rare blood cancer characterized by abnormal white blood cells. Learn about symptoms, causes, diagnosis, and treatment options.
Non-Hodgkin Lymphoma (NHL): Symptoms & Subtypes
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).
