What is the RDW Blood Test? (Red Cell Distribution Width)


The RDW blood test measures how red blood cells change in size and volume. This test is part of a more extensive Complete Blood Count (CBC). The RDW test is usually used to help diagnose anemia, a condition in which red blood cells are unable to carry enough oxygen to the rest of the body. The RDW test can also be performed to diagnose other conditions, including -

  • Iron deficiency
  • Different types of anemia
  • Thalassemia
  • Sickle cell anemia
A high RDW result may indicates other conditions, such as:
  • Chronic liver disease
  • Heart disease
  • Diabetes
  • Kidney disease
  • Cancer

Why does someone need to be screened for red blood cells?

People having symptoms, such as

  • Weakness
  • Fatigue
  • Pale skin
  • Rapid heartbeat
  • Cold hands and feet
  • Shortness of breath
Doctors can also review the RDW test through a CBC if you have:
  • signs of anemia, such as dizziness, pale skin and numbness.
  • a deficiency in iron or vitamins.
  • family history of a blood condition, such as sickle cell disease.
  • severe blood loss as a result of surgery or trauma.
  • a condition affecting the red blood cells has been diagnosed.
  • a chronic condition, such as HIV/AIDS.

What do the results mean?

  • High results - an indication of a deficiency in iron, folate, or vitamin B-12
  • Normal results - it indicates a blood disorder in which the bone marrow does not generate enough blood cells, including red blood cells
  • Low results - If the result is low, there is no hematological disorder associated with a low RDW outcome
This helps to minimize RDW.
  • Eat a balanced diet
  • Stop or quit smoking
  • Avoiding alcohol
  • Get enough sleep
  • Exercise regularly
