Anion gap - All Cations can be measured but some of the anions can't be measured, this creates a viual GAP, called as - Anion gap Measured by: - (Na+) + (unmeasured cations) = (CL-) + (HCO-3) + Unmeasured anions - Since cations do not remain unmeasured, all cations gets measured, therefore :- Anion gap = Na minus - - - 137 - 125 - 12
