How pure is potato starch? Can I rely on it not to include the high amounts of potassium that potatoes do?

I've been unable to find potassium content information for potato starch - the purified, white powder, like corn starch. A lot of products include potato starch, and some, like noodles, are made primarily out of it. As part of my medically-mandated diet, I need to limit my potassium intake. As potato starch is a dried, concentrated product, it might be dangerous for me to eat it if it retains and concentrates potassium as well.
Do you know about the process(es) used to create potato starch, or the actual potassium content of the final product? Is the process standardized enough to have the same result, even across international manufacturers?
