General Information About the Test
Test Process and Preparation
An elevated RDW (Anisocytosis) indicates that very large, normal, and very small cells are present together in a complex mix in the blood (there is size inequality). If there is an iron or B12/Folate deficiency in the body, this value rises rapidly because the bone marrow produces cells in incorrect sizes.
Yes, there can be. If a person is anemic but their RDW value is within normal limits (the cell sizes are nearly equal), the physician suspects the patient is a "Thalassemia Carrier" (Mediterranean anemia) or has anemia of chronic disease, and requests further tests.
No. The RDW is automatically reflected in the report through statistical calculation by the computer based on the data from the standard Complete Blood Count (CBC) test you provide for any disease or check-up.
