What Does RDW Mean and When Should You Be Concerned?

RDW stands for red blood cell distribution width. It is an indicator of the variability of the size of your red blood cells. When RDW is high, it means that there is a lot of variation in the size of your red blood cells. This can be a sign of a number of underlying health conditions. Your RDW is measured with a blood test. The test results will list the RDW as part of the complete blood count (or a separate test if only looking at red blood cells). RDW is reported in two ways:

RDW: This is the standard deviation of the red blood cell distribution width. It measures the average difference in size between red blood cells. A normal RDW is between 11.5 to 14.5%. RDW-CV: This is the coefficient of variation of the red blood cell distribution width. It measures the percentage of red blood cells that differ in size from the average. A normal RDW-CV is between 12%-16%.

If your RDW is high, it is important to see your doctor so that they can run further tests to determine the underlying cause. Some of the conditions that can cause high RDW include:

  • Anemia
  • Thalassemia
  • Sickle cell anemia
  • Iron deficiency
  • Vitamin B12 deficiency
  • Alcohol abuse
  • Liver disease
  • Kidney disease
  • Cancer
  • Certain medications

It is important to note that high RDW does not always indicate a health condition. In some cases, it can be a temporary elevation due to a recent infection or inflammation.

When Should You Be Concerned?

Your doctor will likely want to repeat the blood test to confirm a high RDW. If the RDW remains high, your doctor will likely order additional tests to determine the underlying cause. In general, you should be concerned if your RDW is persistently high and you are experiencing other symptoms, such as fatigue, shortness of breath, or easy bruising. If you have any of these symptoms, it is important to see your doctor right away.

What Level of RDW is Dangerous?

RDW is a measure of the variation in the size of red blood cells. A high RDW can be a sign of several underlying health conditions.

  • Normal RDW: 11.5-14.5%
  • Normal RDW-CV: 12%-16%
  • High RDW: >14.5%
  • High RDW-CV: >16%
  • Persistently high RDW: concerning
  • Symptoms with high RDW: fatigue
  • Symptoms with high RDW: shortness of breath
  • Symptoms with high RDW: easy bruising
  • Underlying causes: anemia
  • Underlying causes: thalassemia

If you have a high RDW, your doctor will likely order additional tests to determine the underlying cause.

Normal RDW: 11.5-14.5%

A normal RDW means that the size of your red blood cells is within the normal range. This indicates that your red blood cells are healthy and functioning properly.

  • Healthy red blood cells: Red blood cells that are normal in size are able to carry oxygen efficiently throughout the body.
  • Normal hemoglobin levels: Hemoglobin is the protein in red blood cells that carries oxygen. A normal RDW indicates that your hemoglobin levels are likely to be normal as well.
  • No underlying health conditions: A normal RDW is typically associated with good overall health and the absence of any underlying medical conditions that could affect the size of red blood cells.
  • RDW can fluctuate: It is important to note that RDW can fluctuate slightly over time. This is normal and does not necessarily indicate a health problem. However, if your RDW is consistently high or low, it is important to see your doctor to rule out any underlying medical conditions.

If you have a normal RDW, it is important to continue to maintain a healthy lifestyle by eating a healthy diet, getting regular exercise, and managing stress. These healthy habits will help to keep your RDW in the normal range and reduce your risk of developing any health problems.

Normal RDW-CV: 12%-16%

RDW-CV is another measure of the variability of red blood cell size. It is expressed as a percentage and is typically reported along with RDW. A normal RDW-CV is between 12% and 16%.

  • Healthy red blood cells: A normal RDW-CV indicates that the size of your red blood cells is within the normal range. This means that your red blood cells are healthy and functioning properly.
  • Normal hemoglobin levels: Hemoglobin is the protein in red blood cells that carries oxygen. A normal RDW-CV indicates that your hemoglobin levels are likely to be normal as well.
  • No underlying health conditions: A normal RDW-CV is typically associated with good overall health and the absence of any underlying medical conditions that could affect the size of red blood cells.
  • RDW-CV can fluctuate: It is important to note that RDW-CV can fluctuate slightly over time. This is normal and does not necessarily indicate a health problem. However, if your RDW-CV is consistently high or low, it is important to see your doctor to rule out any underlying medical conditions.

If you have a normal RDW-CV, it is important to continue to maintain a healthy lifestyle by eating a healthy diet, getting regular exercise, and managing stress. These healthy habits will help to keep your RDW-CV in the normal range and reduce your risk of developing any health problems.

High RDW: >14.5%

A high RDW means that there is a lot of variation in the size of your red blood cells. This can be a sign of several underlying health conditions. Some of the most common causes of high RDW include:

  • Iron deficiency: Iron is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen. If you are iron deficient, your body may produce red blood cells that are too small and too large.
  • Vitamin B12 deficiency: Vitamin B12 is also essential for the production of hemoglobin. A vitamin B12 deficiency can lead to the production of red blood cells that are too large.
  • Anemia: Anemia is a condition in which you have a low number of red blood cells. This can be caused by a variety of factors, including iron deficiency, vitamin B12 deficiency, and chronic diseases such as cancer and kidney disease.
  • Thalassemia: Thalassemia is a genetic disorder that affects the production of hemoglobin. People with thalassemia produce red blood cells that are too small and too thin.
  • Sickle cell anemia: Sickle cell anemia is a genetic disorder in which the red blood cells are shaped like crescents or sickles. These sickle-shaped red blood cells can get stuck in small blood vessels, which can lead to pain, tissue damage, and organ failure.

Other less common causes of high RDW include:

  • Liver disease: Liver disease can interfere with the production of red blood cells.
  • Kidney disease: Kidney disease can lead to the production of red blood cells that are too small and too round.
  • Alcohol abuse: Alcohol abuse can damage the bone marrow, which is where red blood cells are produced.
  • Certain medications: Some medications, such as chemotherapy drugs and antiretroviral drugs, can cause high RDW.

If you have a high RDW, your doctor will likely order additional tests to determine the underlying cause. Treatment for high RDW will depend on the underlying cause.

High RDW-CV: >16%

A high RDW-CV means that the variability in the size of your red blood cells is greater than normal. This can be a sign of several underlying health conditions. Some of the most common causes of high RDW-CV include:

  • Iron deficiency: Iron is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen. If you are iron deficient, your body may produce red blood cells that are too small and too large.
  • Vitamin B12 deficiency: Vitamin B12 is also essential for the production of hemoglobin. A vitamin B12 deficiency can lead to the production of red blood cells that are too large.
  • Anemia: Anemia is a condition in which you have a low number of red blood cells. This can be caused by a variety of factors, including iron deficiency, vitamin B12 deficiency, and chronic diseases such as cancer and kidney disease.

  • Liver disease: Liver disease can interfere with the production of red blood cells.
  • Kidney disease: Kidney disease can lead to the production of red blood cells that are too small and too round.
  • Alcohol abuse: Alcohol abuse can damage the bone marrow, which is where red blood cells are produced.
  • Certain medications: Some medications, such as chemotherapy drugs and antiretroviral drugs, can cause high RDW-CV.

If you have a high RDW-CV, your doctor will likely order additional tests to determine the underlying cause. Treatment for high RDW-CV will depend on the underlying cause.

When to see a doctor

You should see a doctor if you have any of the following symptoms:

  • Fatigue
  • Shortness of breath
  • Easy bruising
  • Pale skin
  • Rapid heart rate
  • Chest pain
  • Abdominal pain
  • Joint pain
  • Swelling in your hands or feet

If you have a persistently high RDW, your doctor will likely order additional tests to determine the underlying cause. Treatment for a persistently high RDW will depend on the underlying cause.

Symptoms with high RDW: fatigue

Fatigue is a common symptom of high RDW. This is because high RDW can lead to anemia, which is a condition in which you have a low number of red blood cells. Red blood cells carry oxygen throughout the body, so if you have anemia, your body will not be able to get the oxygen it needs. This can lead to fatigue, as well as other symptoms such as shortness of breath, dizziness, and headaches.

  • Reduced oxygen delivery: High RDW can lead to anemia, which can reduce the amount of oxygen that is delivered to your body's tissues. This can cause fatigue and other symptoms such as shortness of breath, dizziness, and headaches.
  • Iron deficiency: Iron deficiency is the most common cause of high RDW. Iron is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen. If you are iron deficient, your body may not be able to produce enough hemoglobin, which can lead to anemia and fatigue.
  • Vitamin B12 deficiency: Vitamin B12 is also essential for the production of hemoglobin. A vitamin B12 deficiency can also lead to anemia and fatigue.
  • Chronic diseases: High RDW can also be a sign of a chronic disease, such as cancer, kidney disease, or liver disease. These diseases can all lead to fatigue.

If you are experiencing fatigue along with a high RDW, it is important to see a doctor to determine the underlying cause. Treatment for fatigue caused by high RDW will depend on the underlying cause.

Symptoms with high RDW: shortness of breath

Shortness of breath is another common symptom of high RDW. This is because high RDW can lead to anemia, which is a condition in which you have a low number of red blood cells. Red blood cells carry oxygen throughout the body, so if you have anemia, your body will not be able to get the oxygen it needs. This can lead to shortness of breath, as well as other symptoms such as fatigue, dizziness, and headaches.

  • Reduced oxygen delivery: High RDW can lead to anemia, which can reduce the amount of oxygen that is delivered to your body's tissues. This can cause shortness of breath, as well as other symptoms such as fatigue, dizziness, and headaches.
  • Iron deficiency: Iron deficiency is the most common cause of high RDW. Iron is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen. If you are iron deficient, your body may not be able to produce enough hemoglobin, which can lead to anemia and shortness of breath.
  • Vitamin B12 deficiency: Vitamin B12 is also essential for the production of hemoglobin. A vitamin B12 deficiency can also lead to anemia and shortness of breath.
  • Chronic diseases: High RDW can also be a sign of a chronic disease, such as cancer, kidney disease, or liver disease. These diseases can all lead to shortness of breath.

If you are experiencing shortness of breath along with a high RDW, it is important to see a doctor to determine the underlying cause. Treatment for shortness of breath caused by high RDW will depend on the underlying cause.

Symptoms with high RDW: easy bruising

Easy bruising is another common symptom of high RDW. This is because high RDW can lead to a condition called thrombocytopenia, which is a decrease in the number of platelets in your blood. Platelets are responsible for helping your blood to clot. If you have thrombocytopenia, your blood will not be able to clot properly, which can lead to easy bruising and bleeding.

There are several causes of thrombocytopenia, including:

  • Immune thrombocytopenia (ITP): ITP is an autoimmune disorder in which your immune system attacks and destroys your platelets.
  • Aplastic anemia: Aplastic anemia is a condition in which your bone marrow does not produce enough blood cells, including platelets.
  • Vitamin B12 deficiency: Vitamin B12 is essential for the production of platelets. A vitamin B12 deficiency can lead to thrombocytopenia.
  • Medications: Some medications, such as chemotherapy drugs and anticonvulsants, can cause thrombocytopenia.
  • Alcohol abuse: Alcohol abuse can damage the bone marrow, which can lead to thrombocytopenia.

If you are experiencing easy bruising along with a high RDW, it is important to see a doctor to determine the underlying cause. Treatment for easy bruising caused by high RDW will depend on the underlying cause.

When to see a doctor

You should see a doctor if you have any of the following symptoms:

  • Fatigue
  • Shortness of breath
  • Easy bruising
  • Pale skin
  • Rapid heart rate
  • Chest pain
  • Abdominal pain
  • Joint pain
  • Swelling in your hands or feet

These symptoms can be caused by a variety of underlying medical conditions, including high RDW. If you are experiencing any of these symptoms, it is important to see a doctor right away to get a diagnosis and treatment.

Underlying causes: anemia

Anemia is a condition in which you have a low number of red blood cells. Red blood cells carry oxygen throughout the body, so if you have anemia, your body will not be able to get the oxygen it needs. This can lead to a variety of symptoms, including fatigue, shortness of breath, and easy bruising.

There are many different causes of anemia, including:

  • Iron deficiency: Iron is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen. If you are iron deficient, your body will not be able to produce enough hemoglobin, which can lead to anemia.
  • Vitamin B12 deficiency: Vitamin B12 is also essential for the production of hemoglobin. A vitamin B12 deficiency can also lead to anemia.
  • Chronic diseases: Anemia can also be caused by chronic diseases, such as cancer, kidney disease, and rheumatoid arthritis.
  • Medications: Some medications, such as chemotherapy drugs and anti-inflammatory drugs, can cause anemia.
  • Blood loss: Blood loss can also lead to anemia. This can be caused by injuries, surgery, or heavy menstrual bleeding.

If you are diagnosed with anemia, your doctor will likely order tests to determine the underlying cause. Treatment for anemia will depend on the underlying cause.

Iron deficiency anemia

Iron deficiency anemia is the most common type of anemia. It is caused by a lack of iron in the body. Iron is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen. If you do not have enough iron, your body will not be able to produce enough hemoglobin, which can lead to anemia.

Iron deficiency anemia can be caused by a number of factors, including:

  • Blood loss: Blood loss can lead to iron deficiency anemia, especially if the blood loss is heavy or prolonged. Blood loss can be caused by injuries, surgery, or heavy menstrual bleeding.
  • Poor diet: A diet that is low in iron can also lead to iron deficiency anemia. Iron-rich foods include red meat, poultry, fish, beans, and leafy green vegetables.
  • Absorption problems: Some people have difficulty absorbing iron from their food. This can be caused by celiac disease, Crohn's disease, or other digestive disorders.

Treatment for iron deficiency anemia typically involves taking iron supplements. In some cases, blood transfusions may be necessary.

Vitamin B12 deficiency anemia

Vitamin B12 deficiency anemia is another common type of anemia. It is caused by a lack of vitamin B12 in the body. Vitamin B12 is essential for the production of hemoglobin, the protein in red blood cells that carries oxygen. If you do not have enough vitamin B12, your body will not be able to produce enough hemoglobin, which can lead to anemia.

Vitamin B12 deficiency anemia can be caused by a number of factors, including:

  • Poor diet: A diet that is low in vitamin B12 can lead to vitamin B12 deficiency anemia. Vitamin B12 is found in animal products, such as meat, poultry, fish, and eggs.
  • Absorption problems: Some people have difficulty absorbing vitamin B12 from their food. This can be caused by celiac disease, Crohn's disease, or other digestive disorders.
  • Medications: Some medications, such as metformin and proton pump inhibitors, can interfere with the absorption of vitamin B12.

Treatment for vitamin B12 deficiency anemia typically involves taking vitamin B12 supplements. In some cases, vitamin B12 injections may be necessary.

Underlying causes: thalassemia

Thalassemia is a genetic disorder that affects the production of hemoglobin, the protein in red blood cells that carries oxygen. People with thalassemia produce red blood cells that are too small and too thin. This can lead to anemia, a condition in which you have a low number of red blood cells.

  • Alpha-thalassemia: Alpha-thalassemia is caused by a mutation in the genes that produce the alpha-globin protein. Alpha-globin is one of the two types of globin proteins that make up hemoglobin.
  • Beta-thalassemia: Beta-thalassemia is caused by a mutation in the genes that produce the beta-globin protein. Beta-globin is the other type of globin protein that makes up hemoglobin.
  • Sickle cell anemia: Sickle cell anemia is a type of beta-thalassemia in which the red blood cells are shaped like crescents or sickles. These sickle-shaped red blood cells can get stuck in small blood vessels, which can lead to pain, tissue damage, and organ failure.

Thalassemia is inherited from both parents. If you inherit one copy of a thalassemia gene from each parent, you will have thalassemia trait. Thalassemia trait does not usually cause any health problems. However, if you inherit two copies of a thalassemia gene, you will have thalassemia major. Thalassemia major can cause severe anemia and other health problems.

Symptoms of thalassemia

The symptoms of thalassemia can vary depending on the severity of the condition. People with mild thalassemia may have no symptoms at all. People with more severe thalassemia may experience the following symptoms:

  • Fatigue
  • Shortness of breath
  • Pale skin
  • Rapid heart rate
  • Enlarged spleen
  • Bone pain
  • Delayed growth

Treatment for thalassemia

There is no cure for thalassemia. However, there are treatments that can help to improve the symptoms of the condition. Treatment for thalassemia may include:

  • Blood transfusions
  • Iron chelation therapy
  • Bone marrow transplant
