Potassium blood test: anything better? Are you deficient?

I have the impression that your body wants to control potassium levels in the blood in a very narrow range, and will rob potassium from the cells in order to prevent blood levels from falling too low.

I also have the impression that there's not an easy test to measure potassium levels in the cells.

In fact, I even had a very fancy Spectra-Cell intra-cellular test, and it measured all kinds of things inside the cells, but potassium wasn't one of them.

Other than blood levels of potassium, are there any other ways to rule-out/rule-in a cellular potassium deficiency?

Thanks for any thoughts,

Darn Mac Pro... I researched the issue in the 1990s, and back then a 4/1 K/Na ratio as considered optimal. And I wonder how people who eat only meat can ever get close to it.

I think you are correct about a lack of testing. I have added potassium rich foods to my diet and hope that I am reaching good levels. I can't worry about it beyond that. If I plug my daily diet into a tracker it ususally shows a good ratio of potassium to salt.
