Red Cell Distribution Width-SD (RDW-SD)
Explanation: Red Cell Distribution Width (RDW) measures the variation in the size and volume of red blood cells (RBCs). A high RDW means that the RBCs vary more in size, which can indicate anemia or other blood disorders.
Test purpose: An RDW test is part of a Complete Blood Count (CBC). High RDW may indicate iron deficiency anemia, vitamin B12/folate deficiency, or bone marrow disorders. Normal RDW suggests uniform RBC size and is usually normal.
- Detect different types of anemia.
- Detect iron, vitamin B12, or folate deficiencies.
- Assess bone marrow function and blood disorders.
- Monitor chronic conditions affecting red blood cell production.
