RDW (Red Cell Distribution Width) is a blood test that measures the size variation of your red blood cells (erythrocytes). Red blood cells play a crucial role in oxygen transport by carrying oxygen from the lungs to the body's tissues. The size distribution of the erythrocytes can provide valuable information about your blood count and can be an important factor in the investigation of anemia and other blood diseases.
An RDW test provides a better understanding of your blood health and can be important for a complete blood analysis. The test is primarily used to:
The test is performed through a blood sample where the size distribution of your red blood cells is analyzed. The result is often interpreted together with other blood status parameters such as B-MCV (mean cell volume), hemoglobin and hematocrit to provide a more complete picture of your blood health.
Knowing your RDW value can help you identify potential health problems at an early stage and, if necessary, take steps to improve your blood status and overall health.
A complete blood count (CBC) provides an overview of the composition of the blood and can indicate anemia, infection, or other abnormalities. Blood tests measure levels of red and white blood cells and platelets, which provide important information about oxygen transport, immune defense, and the blood's ability to clot.
