A high RDW (Red Cell Distribution Width) means that the sizes of your red blood cells vary more than is considered normal. This can be a sign of anemia or other related conditions. It indicates that your body is producing red blood cells of different sizes, which may be due to a variety of factors, including iron deficiency, vitamin B12 deficiency, folate deficiency, and other health issues. Your doctor will need to look at other tests to determine the underlying cause of your high RDW.
- Iron deficiency: A lack of iron can affect the production of red blood cells, leading to a high RDW.
- Vitamin B12 deficiency: Vitamin B12 is essential for the production of red blood cells. A deficiency can lead to a high RDW and anemia.
- Folate deficiency: Folate is another nutrient necessary for red blood cell production. A lack of folate can result in a high RDW and anemia.
- Other conditions: Some other conditions, such as chronic diseases, autoimmune disorders, and bone marrow disorders, can also cause a high RDW.
While a high RDW can indicate a health issue, it's important to note that it's not always a cause for concern. Your doctor will consider your individual medical history and other test results to make a diagnosis.
