red blood cell distribution width increased - what is it?
Miscellaneous / / August 12, 2017
Handing on a general analysis of blood in hospitals, people know about that in the course of laboratory investigations, determine the number of certain cells or blood cells in the body of a human.More precisely, the blood of 50-60% - a liquid plasma and platelets, red blood cells and white blood cells - shaped suspended elements, which accounted for respectively 40 to 50% of the total composition of the blood.
Regarding the red blood cells, these red corpuscles:
- regulate acid-base balance;
- adsorbed from plasma lipids, amino acids;
- maintain isotonicity;
- carry oxygen to the tissues of the lungs and return carbon dioxide to the lungs from the tissues.
Because it is clear that a breach of the number of red blood cells in the blood leads to all sorts of diseases in humans.
main component of red blood cell - hemoglobin - special respiratory pigment.
Complete blood count
Thus, when a patient takes blood count is checked, in particular, and the total number of red blood cells and hemoglobin conc
- Elevated levels of red blood cells leading to clogging of capillaries;
- low number of red blood cells lead to oxygen starvation.
Thus to distinguish between the following erythrocyte indices:
- mean corpuscular volume - MCV;
- Average hemoglobin content in an erythrocyte - MCH;
- average concentration of hemoglobin - MCHC.
define these parameters special device - hematology analyzer.It also shows another parameter of blood - red blood cell distribution width - RDW.
erythrocyte distribution width is measured in percentage and is considered the norm index from 11.5 to 14.5.
more about RDW
So, is that the width of the distribution of red blood cells is increased, or vice versa is almost zero.This means that the erythrocytes present in the blood are too different from each other in size, and the zero embodiment - are almost identical.In the first case there - Anisocytosis, which, incidentally, has no independent nature, ie,necessarily caused by any reason.Reducing the size of red blood cells - a slow process of blood formation and the emergence of degenerative red blood cells.An increase in the size of their manifest indication of increased production.And when too many micro- and makroelektrotsitov, body sounds the alarm in the blood.
diseases Most often the doctor puts the patient such a diagnosis - anemia.This appears due mikroanizotsitoz hypochromic anemia, and macro - pernicious anemia.But in both cases, increased erythrocyte distribution width.Both options require long-term treatment, as a result of which, the formation of new, normal blood cells.By the way, there are a number of other diseases in which there is Anisocytosis.If etomikrotsitoz, there may be:
- Lead poisoning;
If macrocytosis, it is not excluded:
- Diffuse liver disease;
- folic acid deficiency anemia.
In any case, the final, the only sure diagnosis supply specialist, so a visit to the doctor is necessary.Because right on the basis of analysis conclusion can do a competent doctor.More than once we have seen, both in panic ran along the corridor young mother with the results of analyzes in the hands and wailed, even knowing that some of the parameters in blood tests of the child, even higher than that of an adult.
Interestingly, the red blood cells in newborns is bigger than that of their parents.
