Polycythemia or an increase in red blood cells
the water is getting to high elevations
The number of RBC will increase
If you expose red blood cells to a high concentration of NaCl (salt), water will move out of the cells through osmosis, causing them to shrink and potentially undergo hemolysis (bursting). This process is known as crenation.
Yes, RA can cause elevations on the white blood cells. So can virues, stress, and other things. I have RA and every time i get a CBC (complete blood count) I have elevated white blood cells. I am always told its not high enough to be concerned and that it is probably from my RA since I suffer alot from inflammation. Ask your doctor if you are overly concerned.
This phenomenon is an example of acclimatization, where the body adjusts to a new environment to maintain its normal functioning. In this case, increased red blood cell production is a physiological adaptation to compensate for lower oxygen levels at high elevations.
MID is Minimum Inhibitory Dilution in blood tests. They measure rare cells and precursor white cells. A high MID in blood tests means a high level of the rare cells.
Increased hematocrit is the effect of living at high elevation. The human body compensates by increasing the volume of RBC in order to absorb as much oxygen on areas of high atmospheric pressure.
demerit of high red blood cell
The percentage goes up. (Hematocrit is the percentage of red blood cells in a sample of whole blood, so if an elevated number of red blood cells is produced by your bone marrow, your hematocrit level should rise).
High red blood cells
If red blood cells were placed into a beaker with plasma, the red blood cells would absorb the liquid and start to expand due to the osmotic pressure. Eventually, the red blood cells may burst (hemolysis) if the osmotic pressure is too high compared to their structural integrity. This would release hemoglobin into the plasma.
In advanced stages of Emphysema your red blood cells can be affected and it can cause them to have a high MCV blood result reading. Infections can also cause the red blood cells to rise as well.
