KnowraHematologyHematologyHematology is the medical specialty and scientific study of blood, blood-forming organs, and blood disorders.BriefConnectComplete blood count: A blood test that measures blood-cell counts and hemoglobin concentration. It is a routine starting point for detecting abnormalities in red cells, white cells, and platelets.Anemia: A condition in which the blood has too little hemoglobin or too few red blood cells to carry oxygen adequately. It is among the most common clinical problems evaluated in hematology.Flow cytometry: A laboratory method that identifies and counts cells by measuring light signals from cells passing through a laser. It distinguishes blood-cell populations and helps classify leukemias and lymphomas.Oncology: The medical specialty concerned with the prevention, diagnosis, and treatment of cancer. Hematologic cancers sit at the boundary between blood-focused practice and cancer medicine.Gene therapy: A treatment that changes genetic material in cells to prevent or treat disease. It can address the inherited cause of some blood disorders, but durability and access remain concerns.Hematopoiesis: The process by which blood cells develop from stem and progenitor cells. Blood disorders often arise when this cell-production process fails or changes.Leukemia: A cancer of blood-forming tissues characterized by abnormal proliferation of white-cell precursors or cells. Its diagnosis and treatment depend on identifying the malignant blood-cell lineage.Coagulation test: A laboratory assay that measures aspects of the blood-clotting process. Clotting assays help locate defects in coagulation and monitor anticoagulant treatment.Transfusion medicine: The specialty concerned with blood donation, blood components, compatibility, and transfusion practice. It shares blood-product care with hematology while concentrating on safe collection and transfusion.CAR T-cell therapy: A cancer treatment using a patient’s T cells engineered to recognize and attack target cells. Its success in some blood cancers is balanced by serious toxicities and uneven availability.Show all 28Linked from 4 pagesMedical laboratoryRelated: Blood counts and cell examinations reveal anemia, infection, and blood cancers.Hemolytic anemiaNarrower topic: Hemolytic anemia is evaluated and managed within this specialty.Clinical chemistryCompared with: Hematology focuses chiefly on cells, while clinical chemistry measures dissolved substances and molecular analytes.Show all 4
