In brs physi, the formula is Na - (Hco3 + Cl), K is mainly intracelluar. Is there any explanantion in kaplan? Thanks.

hi it is
Na -(HCO3+Cl)
becos pottasium extracellular is normally less than 5 meq..it is ignored...
qs relavant to increased anion gap will definitely show a wide anion gap not with in that 5 meq difference..
so eitherway u calculate...no problem...
