Please define.

Would this be a message delivered to you full of anions? (Something like a candy gram that is a message full of candy?)

Seriously, though, I have not heard of an aniongram.

I have, however, heard of an anion gap.

First:

anion - this is an ion carrying a negative charge. It is attracted by, and travels to, the anode.

ion - A particle carrying an electric charge.

cation - an ion that carries a positive charge.

anion gap - This is a concept used to estimate electolyte levels in the blood and the conditions that influence them. This can be used to help determine acid base disturbances.

I hope this is actually what you were after! If not, please let me know if we can help further!
