How Blood Tests Reveal Secrets About Microcytic Anemia
Published: Apr 03, 2024
Blood tests are essential tools for diagnosing microcytic anemia. Learn how these tests work and what they reveal about your health.
Complete Blood Count (CBC)
The CBC is a fundamental test that measures various components of blood, including RBC size and hemoglobin content. The mean corpuscular volume (MCV) and red cell distribution width (RDW) are key parameters in identifying microcytic anemia.
Peripheral Blood Smear
A peripheral blood smear provides a closer look at the shape and size of RBCs, offering clues to the cause of anemia. It can reveal variations in cell size and identify specific cell forms like target cells or teardrop cells.
Iron Studies and More Tests
Iron studies, including measurements of serum ferritin and total iron-binding capacity, help determine if iron deficiency is the cause of anemia. These tests, along with others like hemoglobin analysis, guide the diagnosis and treatment of microcytic anemia.
