Disorders of red and white blood cells, such as anemia and leukemia

Abstract

Background: Disorders of red and white blood cells, such as anemia and leukemia, can reflect both hematological and non-hematological conditions. Anemia, a common clinical challenge, necessitates thorough evaluation when accompanied by symptoms like splenomegaly, lymphadenopathy, or bleeding tendencies. Aim: This article aims to explore the diagnostic approach to blood disorders, emphasizing the significance of initial screening tests and their interpretations. Methods: A comprehensive review of laboratory tests, including hemoglobin concentration, white blood cell count, and peripheral blood smear examination, is conducted. The article discusses the interpretation of results, considering factors such as age, sex, and ethnic background. Results: The findings illustrate that abnormalities in blood cell counts can indicate various underlying conditions. Increased cell counts may suggest myeloproliferative neoplasms, while decreased counts may arise from factors such as hypersplenism, infections, or myelosuppressive agents. The article further categorizes anemia into microcytic, macrocytic, and normocytic types, with flowcharts outlining the investigation sequence for each type. Conclusion: Understanding the complexities of blood disorders requires a systematic approach to diagnosis. Utilizing basic screening tests effectively can guide further investigations, ultimately aiding in the identification and management of underlying hematological conditions.
