When your bones hurt, it is very important to know how your red
blood cells are functioning. Sounds odd doesn't it?
When there is severe red blood cell anemia, red blood cells may
start reproducing outside of the spine - it can cause spinal cord
compression... per one so diagnosed: "Once this happens you
have a 72 hour slide period to have surgery to release the
compression or a bone marrow transplant."
For exact terminology

Turns out that as long as the bone marrow is able to compensate
for early death of red blood cells, the anemia won't show up in
what is normally tested for such: hemoglobin, hematocrit, even red
blood cell counts (red blood cell count can be omitted from
laboratory recommended list of tests needed). Retic ratio may give
an indication. Are your red blood cells low functioning?
If you suspect benzene exposure (which reportedly suppresses
production of new red blood cells rather than simply killing
existing red cells), a more usual marker of "benzene
poisoning" is an abnormally low lymphocyte count. So an
absolute cell count that can be done in a regular blood test is an
whether you suspect a chemical exposure or oil

the red blood cells
