Rdw Standard Deviation High

What does Rdw stand for in blood work?

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.

Your cells need oxygen to grow, reproduce, and stay healthy..

What does lymphocytes mean in a blood test?

Lymphocytes are a type of white blood cell. They play an important role in your immune system, helping your body fight off infection. Many underlying medical conditions can cause lymphocytosis. High lymphocyte blood levels indicate your body is dealing with an infection or other inflammatory condition.

What does MCHC mean in a blood test?

A similar measure to MCH is something doctors call “mean corpuscular hemoglobin concentration” (MCHC). MCHC checks the average amount of hemoglobin in a group of red blood cells.

What can cause your red blood cells to be low?

Diseases and conditions that cause your body to produce fewer red blood cells than normal include:Aplastic anemia.Cancer.Certain medications, such as antiretroviral drugs for HIV infection and chemotherapy drugs for cancer and other conditions.Chronic kidney disease.Cirrhosis.Hodgkin’s lymphoma (Hodgkin’s disease)More items…

Why are my red blood cells low?

A low RBC count could also indicate a vitamin B6, B12 or folate deficiency. It may also signify internal bleeding, kidney disease or malnutrition (where a person’s diet doesn’t contain enough nutrients to meet their body’s needs).

What does it mean if your MCH blood test is high?

High MCH scores are commonly a sign of macrocytic anemia. This condition occurs when the blood cells are too big, which can be a result of not having enough vitamin B12 or folic acid in the body. High MCH scores may also be the result of the following: liver diseases.

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 Rdw standard deviation mean?

RDW is the standard deviation (SD) of the red cell volume divided by the mean corpuscular volume (MCV). Because higher MCV also predicts mortality risk, we hypothesized that RDW-SD (the RDW numerator) predicts mortality more strongly than RDW.

What does RDW 15.4 mean?

Higher RDW values indicate greater variation in size. Normal reference range of RDW-CV in human red blood cells is 11.5–15.4%. If anemia is observed, RDW test results are often used together with mean corpuscular volume (MCV) results to determine the possible causes of the anemia.

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 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…

Can dehydration cause high MCV?

High values can indicate polycythemia or dehydration. MCV (Mean Corpuscular Volume) is the average size of red blood cells in a blood sample.

What is normal range for Rdw-SD?

The normal RDW-SD range for adults is 40.0 – 55.0 fL.

What does high MCV and high RDW 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 does it mean when RDW is low on blood test?

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 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.

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).
