What is the width of red blood cell distribution?
The state of red blood cells is often an individual's health indicator. One test that is sometimes performed helps to measure the width of red blood cell distribution (RDW); This can determine how the cells in the sample differ in size. However, measurements generally do not represent the physical average. It usually represents the width of the graphic curve that shows how the volume of cells changes. The normal range is usually between 11% and 15% in the human body.
The width of red blood cell distribution is usually determined mathematically; The formula usually includes an average corpuscular volume or an average amount of space that each cell occupies. The mathematical principle of the standard deviation is applied to the value and divided by an average volume. The result is then multiplied by 100 to determine RDW. Medical laboratories usually have tools that can pick up the pulses produced by red blood cells; Thicker impulses are generally produced by larger cells, while weaker usually come from smaller cells.
Laboratory messages often indicate a normal range of red blood cell distribution. However, ranges may vary depending on the type of device used for measurement. If RDW is high in a blood test, it generally means that cells differ relatively in size; Anemia caused by iron deficiency is sometimes the cause. Low levels of vitamin B12 or folic acid often also reduce the number. The carbon in the vitamins required by the body may miss the normal function.
If the width of red blood cell distribution is high, there may also be a blood disorder that affects the production of hemoglobin, which carries oxygen. Other conditions may cause red blood cells to fall into fragments, which usually causes RDW to rise. On the other hand, the width of red blood cell distribution is often a problem indicator. The type of anemia can reduce the number if there is an abnormally low number of cells, yet they are relatively large. NedThe remains of certain vitamins may also be the reason for the low percentage of RDW.
The width of red blood cell distribution can correlate with the results of other health conditions. High variability of blood cell size often leads to less optimistic prognosis for people with heart failure based on studies. The number may be insufficient production of new cells and their more frequent destruction than usual, thus complicating the basic health.
