Unfortunately, without REPLACING your blood with something, the percent concentration of anything harmful in your blood with be the same. I wonder if it requires a quick replacement with a large percentage of the saline solution to have any effect.

""" The average adult has about 10 pints of blood in his body. Roughly 1 pint is given during a donation. A healthy donor may donate red blood cells every 56 days """
The original article says HALF the blood plasma was replaced. So if I understand this correctly, a blood donation would need to be done 5 times to match the amount taken out.
Is there an option to get a saline solution to replace blood volume when donating blood?
Not necessarily. If the process that produced the bad stuff is slower than serum production, the concentration will be lower. If it’s the same, for example, if it’s a problem with the serum production processes themselves, it won’t.
