What reason does physical examination say red blood cell count is on the high side?
summary
Two days ago, I went to have a physical examination. Other data of the physical examination results were normal, that is, the red blood cell count was a little higher, and other aspects were normal. I didn't know what to do, so I began to think about it when I came back. So, physical examination says red blood cell count is on the high side what reason causes?
What reason does physical examination say red blood cell count is on the high side?
The first reason is: red blood cells, hemoglobin and hematocrit decreased more common in anemia, high and more related to blood concentration. Platelet distribution width, average platelet volume and large platelet ratio are calculated by the instrument according to the number of platelets. If the platelets are normal, no symptoms, slight abnormalities, more meaningless, no treatment is needed.
The second reason is: the red blood cell count is on the high side, that is to say, the red blood cells in your body are slightly higher than the normal range. Don't worry, there are individual differences in the red blood cell count, and different machines of cell count will also cause differences. Your count is just on the high side, no big problem.
The third reason is: erythrocytosis: there are many causes, including relative erythrocytosis caused by reduced plasma volume, secondary erythrocytosis caused by tissue hypoxia, and polycythemia vera with unknown causes.
The fourth reason is that the main parameter of red blood cell is slightly higher, which may be related to blood concentration. We can test the whole set of Hemorheology and blood lipid, measure the blood pressure and make ECG. Need to pay attention to is to avoid blood viscosity is not a problem, if the above examination is normal, it does not matter.
The fifth reason is: the relative increase of red blood cells: the decrease of plasma volume is caused by the relative increase of red blood cell volume and blood concentration. It can be seen in sweating, vomiting, diarrhea, burn, diabetes, ketoacidosis, diabetes insipidus, etc.
The sixth reason is: pathological increase: severe vomiting, diarrhea, a large number of sweating, large area burn patients, diabetes insipidus, hyperthyroidism, diabetes acidosis, etc. due to excessive water loss in the plasma, resulting in blood concentration, there will be a significant increase in the amount of red blood cells and red blood protein.
matters needing attention
In fact, the high red blood cell count is also normal, the general examination will have more or less error, this does not have much clinical significance, as long as there is no special this, do not need to care too much.
