What does RDW mean in a blood test? Inother words, no problem! RDW refers to the variation in size if your red blood cells. A … low RDW means that the cells are all roughly the same size. A high RDW means there isa high variation in the sizes of the cells and usually means a deficiency of iron and/or B12.f the RDW level is increased and the MCV level is normal. This can be caused by the beginning stages of a decrease in vitamin B12 or folic acid (a type of vitamin) in the body. It can also be caused by the beginning stages of iron deficiency anemia.

What does it mean if I have low RDW? 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.

- RDW stands for the red blood cell distribution width. This is a standard reported measure on a complete blood count (CBC) lab test. It measures the variability in red blood cell size. In the normal state, red blood cells are continually being produced and removed from the blood at a steady rate. The young, immature red blood cells are larger than mature red blood cells.

Red blood cell distribution width Human red blood cells. Red blood cell distribution width (RDW-CV or RCDW and RDW-SD) is a measure of the range of variation of red blood cell (RBC) volume that is reported as part of a standard complete blood count. Usually red blood cells are a standard size of about 6-8 μm in diameter.Certain disorders, however, cause a significant variation in cell size. Higher RDW values indicate greater variation in size. Normal reference range of RDW-CV in human red blood cells is 11.5-14.5%.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.uman red blood cells.

A high baseline RDW was found to be associated with hemoglobin level (P<0.05; Table 2) and white blood cell count. The latter was also significantly different among the RDW groups (P<0.01; Table 1).

What is RDW in CBC Blood Test? RDW is an early marker of several types of anemia, that’s because RDW value means how red cells sizes are distributed in the blood sample, the normal RDW value means that RBCs are in normal size or the same size, high or low RDW value means that the RBCs show variant sizes, in many types of anemia, RBCs appear in abnormal sizes which s detected by RDW value.

These include sickle cell disease, chronic liver disease or myelodysplastic syndrome. Other problems might include early stages of folate, vitamin B12 or iron deficiency.

- Quick Answer. A high RDW blood test result may indicate anemia due to either iron deficiency or a deficiency of folate and vitamin B12, according to Wikipedia. It may also be a result of a recent hemorrhage. False high RDW readings sometimes occur when the wrong type of blood is used for the test.

How can we interpret the value of RDW in complete blood count? In observing the RDW and the red cell plots showing this value, the level of response to the treatment of anaemia within that patient can be assessed. A good response to iron therapy can give a high RDW >20 and a clear double-peak can be observed. A poor response to treatment will have a small / negligable change in RDW from the norm.

What Is a High MCHC Level? Newport Natural News says that when the MCHC level is high, doctors often look for problems with nutrition and when the MCHC levels are low, the doctors are often looking for anemia in the patient. When measuring the MCHC, doctors will also often measure the RDW or red cell distribution. This calculates the percentage of the cell size variation, states Lab Tests Online. The MCHC level is a part of the standard CBC blood test, says Newport Natural News.
