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.
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.
Eosinophilic Asthma
Eosinophilic asthma is a severe subtype of asthma, driven by high eosinophil levels. It often resists standard treatments and may not be allergy-related.
White Blood Cells (WBCs)
White blood cells (WBCs), also known as leukocytes, are the body’s dedicated defense force. These diverse warriors, patrolling the bloodstream and tissues, play a crucial role in the immune system.
Primary Myelofibrosis (PMF)
Primary Myelofibrosis (PMF) is a rare blood cancer affecting bone marrow, causing abnormal blood cell production & potential for enlarged spleen.
Essential Thrombocythemia (ET)
Essential thrombocythemia (ET) is a chronic myeloproliferative neoplasm (MPN) characterized by an abnormal increase in platelet production by the bone marrow.
Polycythemia Vera
Polycythemia vera is a rare blood cancer where the bone marrow makes too many red blood cells, thickening blood and raising clot risks.
Myeloproliferative Neoplasms (MPNs)
Myeloproliferative neoplasms (MPNs) are blood cancers causing overproduction of blood cells. They can be chronic and require monitoring, with some risk of transforming to leukemia. Early diagnosis is key.
Leukemia: An Overview
Leukemia: Hematopoietic malignancy affecting blood cell production, presenting with cytopenias, blasts in peripheral blood, and requiring prompt diagnosis & treatment.
