Haven't been able to find scientific evidence, medical studies, or any other hard evidence on the benefits of platelet/plasma donations where only red blood cells are returned to the donor.
I have started, and plan to donate platelets regularly at a non-profit blood bank; the apheresis machine used collects platelets and plasma, and I was told that "only red blood cells are returned"
During this 90 minute process, about half the blood in my body goes through this machine a small amount at a time... while in this high tech machine, the inner compartment shakes vigorously and I gather this is separating everything
with the help of anticoagulants ... in a way I believe this machine is "skimming"
everything above the red blood cells and returning only the red blood cells to me...
I understand that with a whole blood donation, the benefits at least for me a man
are the reduction of high iron levels... but if I understand correctly the iron in a platelet/plasma donation is returned back to me since iron and red blood cells are less buoyant?
So if hypothetically I were to donate platelets/plasma regularly, and essentially anything more buoyant than red blood cells were "skimmed"
What is being skimmed off? White Blood Cells? toxins? cholesterol plaque? dissipated proteins? glucose? hormones? carbon dioxide?
Links I have read but no clear answer:
and extensive Google searches...
