Question: Is High RDW Serious?

Why would someone have a high RDW?

High results 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 the normal range for Rdw SD?

The width of the distribution curve is measured at the point that is 20% above the baseline. Since the RDW-SD is an actual measurement, it is not influenced by the MCV and more accurately reflects the red cell size variance. The normal RDW-SD range for adults is 40.0 – 55.0 fL.

What causes anemia?

The most common cause of anemia is low levels of iron in the body. This type of anemia is called iron-deficiency anemia. Your body needs a certain amount of iron to make hemoglobin, the substance that moves oxygen throughout your body. However, iron-deficiency anemia is just one type.

What does a low MCHC mean in a blood test?

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. Hemoglobin is responsible for the red color in blood and for circulating oxygen around the body.

Can high RDW mean cancer?

Accordingly, elevated RDW was associated with more advanced cancers and worse prognosis in a study of 146 patients with multiple myeloma,10 and a correlation was found between elevated RDW, cancer stage and prognosis among lung cancer patients.

What does Rdw mean in a blood 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 diseases cause large red blood cells?

AdvertisementVitamin B-12 deficiency.Folate deficiency.Liver disease.Alcoholism.Hypothyroidism.A side effect of certain medications, such as those used to treat cancer, seizures and autoimmune disorders.Increased red blood cell production by the bone marrow to correct anemia, for example, after blood loss.More items…

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 is Microcytic anemia?

Microcytic anemia definition Microcytosis is a term used to describe red blood cells that are smaller than normal. Anemia is when you have low numbers of properly functioning red blood cells in your body. In microcytic anemias, your body has fewer red blood cells than normal.

What is MCV MCH MCHC RDW in blood work?

MCV, MCH, MCHC, and RDW. Red blood cell indices are calculations that provide information on the physical characteristics of the RBCs: Mean corpuscular volume (MCV) is a measurement of the average size of a single red blood cell.

What does high RDW and normal MCV mean?

A person may have: High RDW and normal MCV. This suggests a deficiency of iron, B-12, or folate. It may also indicate chronic liver disease. High RDW and low MCV.

What are the symptoms of high red blood cell count?

If you have a high RBC count, you could experience symptoms such as:fatigue.shortness of breath.joint pain.tenderness in the palms of the hands or soles of the feet.itching skin, particularly after a shower or bath.sleep disturbance.

Why is Rdw high in iron deficiency anemia?

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.

What does a low RDW mean?

Deleted profile. A low RDW (below 10.2%) means that the red blood cells vary very little in size. One reason for a low RDW level is macrocytic anemia. Another cause of a low RDW level is microcytic anemia. In these two disorders the red blood cells do not vary much in size because they are either all small or all large …

What is the difference between Rdw SD and RDW CV?

Red blood cell distribution width standard deviation (RDW-SD) particle size distribution. RDW-SD is the arithmetic width of the distribution curve measured at the 20% frequency level. The RDW-CV and RDW-SD are measures of the dispersion of data around the mean. The more spread apart the data, the higher the SD.

What does RDW 16.1 mean?

A low RDW means your red blood cells are all about the same size. A high RDW means you have both very small and very large red blood cells. You may also have a “normal” RDW. A normal RDW range is 12.2%–16.1% for women and 11.8%–14.5% for men. But that doesn’t always mean you’re in perfect health.

How do you treat high red blood cell count?

If a medical condition is causing a high red blood cell count, your doctor may recommend a procedure or medication to lower it. In a procedure called a phlebotomy, a health professional inserts a needle into your vein and drains blood through a tube into a bag or container.

How can I lower my red blood cells naturally?

If you have a high RBC count:Exercise to improve heart and lung function.Eat less red meat and iron-rich foods.Avoid iron supplements.Keep yourself well hydrated.Avoid diuretics, including coffee and caffeinated drinks.Stop smoking, especially if you have COPD or pulmonary fibrosis.More items…
