Quick Answer: What Does It Mean If Your RDW Is Low?

Why does iron deficiency increase Rdw?

However, a varied size distribution of red blood cells is a hallmark of iron deficiency anemia, and as such shows an increased RDW in virtually all cases.

In the case of both iron and B12 deficiencies, there will normally be a mix of both large cells and small cells, causing the RDW to be elevated..

How do you fix anemia?

Treatment might include oxygen, pain relievers, and oral and intravenous fluids to reduce pain and prevent complications. Doctors might also recommend blood transfusions, folic acid supplements and antibiotics. A cancer drug called hydroxyurea (Droxia, Hydrea, Siklos) also is used to treat sickle cell anemia.

What does high RDW and low MPV mean?

It has been shown to increase the platelet number and decrease the MPV in patients with cancer [29]. So the higher RDW and lower MPV can be observed in chronic inflammation such as attack-free FMF patients.

What is MCV MCH MCHC RDW in blood work?

The RBC indices are comprised of four different components known as the mean corpuscular hemoglobin concentration (MCHC), the mean corpuscular volume (MCV), the mean corpuscular hemoglobin (MCH), and the red cell distribution width (RDW).

What is Macrocytic anemia?

Macrocytic anemia, then, is a condition in which your body has overly large red blood cells and not enough normal red blood cells. Different types of macrocytic anemia can be classified depending on what’s causing it. Most often, macrocytic anemias are caused by a lack of vitamin B-12 and folate.

What is considered high RDW?

A high RDW (over 14.5%) means that the red blood cells vary a lot in size. A normal RDW is 11.6 to 14.6%, but researchers from the Intermountain Medical Center Heart Institute found that patients with a RDW level greater than or equal to 12.9% had an increased risk for depression.

What will happen if MCV is low?

The MCV will be lower than normal when red blood cells are too small. This condition is called microcytic anemia. Microcytic anemia may be caused by: iron deficiency, which can be caused by poor dietary intake of iron, menstrual bleeding, or gastrointestinal bleeding.

What happens if MCH count is low?

A low MCH value typically indicates the presence of iron deficiency anemia. Iron is important for the production of hemoglobin. Your body absorbs a small amount of iron that you eat in order to produce hemoglobin.

What is Rdw SD normal range?

Reference Range of the Red Cell Distribution Width (RDW) The reference range for RDW is as follows: RDW-SD 39-46 fL. RDW-CV 11.6-14.6% in adult.

What causes low Rdw in blood count?

a diet low in iron, vitamin B-12, or other nutrients. a family history of blood disorders, including thalassemia or sickle cell anemia. chronic illness, such as diabetes, HIV, or Crohn’s disease. dizziness, weakness, pale skin, or other symptoms of anemia.

How do you get Rdw?

It is calculated by dividing the standard deviation of the mean cell size by the MCV of the red cells and multiplying by 100 to convert to a percentage. A normal range for the RDW-CV is approximately 11.0 – 15.0%.

What causes MCH to be low?

Low MCH levels usually occur as a result of iron deficiency that has led to anemia. Doctors may recommend that individuals add more iron and vitamin B6 to their diet. Eating vitamin C and fiber, along with foods that contain iron, may also help increase the MCH levels.

What is Microcytic anemia?

Microcytic anemia is defined as the presence of small, often hypochromic, red blood cells in a peripheral blood smear and is usually characterized by a low MCV (less than 83 micron 3). Iron deficiency is the most common cause of microcytic anemia.

What does high RDW and normal MCV mean?

• A high RDW indicates a large variation in size of RBCs. If the MCV is normal and the RDW is high, there is a mixture of large and small RBCs. If the RDW is normal and the MCV is high, the RBCs are likely all macrocytic. If the MCV and RDW are both normal, the RBCs are likely all about the same normal size.

What happens if you have high red blood cells?

A high RBC count may be a result of sleep apnea, pulmonary fibrosis, and other conditions that cause low oxygen levels in the blood. Performance-enhancing drugs like protein injections and anabolic steroids can also increase RBCs. Kidney disease and kidney cancers can lead to high RBC counts as well.

What happens if RDW is low?

What does it mean if you’re having low RDW? A low RDW is desirable since it is a sign that your RBCs are uniform in size. A low RDW is not a cause for concern. But even if you have a low RDW, still you may have a blood disease.

What does Rdw mean on a blood test?

What is a red cell distribution width test? A red cell distribution width (RDW) test is a measurement of the range in the volume and size of your red blood cells (erythrocytes). Red blood cells move oxygen from your lungs to every cell in your body.

What does low MCV and MCH mean?

Common conditions resulting in a hypochromic microcytic anemia (low MCV and MCH) include thalassemia and iron deficiency; and, less commonly, anemias associated with chronic inflammatory conditions, genetic determinants for Hb C, congenital defects in copper metabolism, some forms of sideroblastic anemia, and other …

Is high RDW serious?

If your RDW is too high, it could be an indication of a nutrient deficiency, such as a deficiency of iron, folate, or vitamin B-12. These results could also indicate macrocytic anemia, when your body doesn’t produce enough normal red blood cells, and the cells it does produce are larger than normal.

What is MCHC in blood test low?

A low mean corpuscular hemoglobin concentration (MCHC) shows that someone’s red blood cells do not have enough hemoglobin. Hemoglobin is an iron-rich protein, and a lack of it may indicate anemia.
