I was told this by a researcher at the blood center. Basically
apheresis is a centrifical process as I understand it. Anything
heavier than the red blood cells is extracted, then the red blood
cells are fed back to you. The result is a large bag filled with a
milky yellow somewhat viscous liquid.

Because of my size and platelet count, they routinely take double
and occasionally triple batches from me. It normally takes 1 1/2 to
two hours. So I guess they're actually extracting a significant
portion of the lipid in the bloodstream.

I'll see if I can find a reference for this.
