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.
FAQs
What does a CBC test for?
A CBC measures blood components, including RBC size, to detect anemia.
How does a blood smear help diagnose anemia?
It reveals RBC shape and size variations, indicating possible anemia causes.
Why are iron studies important?
Iron studies confirm if iron deficiency is causing microcytic anemia.
Can a CBC detect microcytic anemia?
Yes, CBC parameters like MCV and RDW indicate microcytic anemia.
Key Takeaways
Blood tests are invaluable in identifying and understanding microcytic anemia.
