RDW is the Acronym for Red Cell Distribution Width, which means in Spanish amplitude of distribution of erythrocytes, and shows the variation in size between red blood cells being this variation called anisocytes.
In this way, when their value is high in hematology, it means that red blood cells are larger than normal, and could be seen in very large and very small erythrocyte blood vessels. When the value is due to the reference value, it is usually of no clinical importance, only if RDW is included, other indices are also subject to normal value, such as CMV, for example. Know what VCM is.
- RDW is one of the parameters that make up hematology and.
- Along with the other results offered by the test.
- It is possible to check how the production of blood cells and the general state of the person is going.
- When the outcome of RDW is changed.
- It is possible to distrust certain situations.
- Such as anemia.
- Diabetes or liver problems.
- As diagnosis should be made from the complete blood formula analysis and biochemical tests.

The reference value of RDW in hematology is 11 to 14%, however, this result may vary by laboratory, so if the value is due to the debate about this percentage, it may have different meanings, so it is always important that the value be evaluated by the doctor who requested the test.
Anisocytosis is completed when RDW increases, and a large variation in size between erythrocytes can be observed in the blood fleet. RDW can be increased in certain situations, such as:
In addition, people receiving chemotherapy or certain antivirals may also have an increase in RDW.
RDW is usually of no clinical importance when interpreted in isolation, however, if other changes in blood count could indicate anemia caused by a chronic disease such as liver disease or kidney problems. , HIV, cancer, diabetes, for example.
This test is often requested in cases of suspected anemia, onset of symptoms in the mares, pale skin fatigue for example. See the main symptoms of anemia.
For this reason, your doctor may also order an exam when the tube is present:
Sometimes this test may even be ordered during a routine blood test, if it exists in the specific cause.
To highlight hematology and therefore RDW, there is no need for a test, however, the blood formula is usually monitored at the same time as other blood tests that require a minimum of 8 hours.
Normally, the blood test takes less than 5 minutes and is easily done in the hospital or in any clinical examination by removing a small blood sample through the vein.
