Sodium (Na⁺ )	mEq/L
Potassium (K⁺)	mEq/L
Chloride (Cl-)	mEq/L
Bicarbonate (HCO3-)	mEq/L

Anion Gap = (Na⁺ + K⁺) - (Cl^- + HCO3^-)	mEq/L
Anion Gap (No K) = (Na⁺) - (Cl^- + HCO3^-)	mEq/L
Delta Gap = (Anion Gap (No K) - 12 )	mEq/L

The anion gap (AG) represents the concentration of all the unmeasured anions in the plasma.

Causes of a High Anion Gap : MUDPILERSO

M-ethanol
U-remia
D-iabetic Ketoacidosis (DKA) or starvation ketosis
P-araldehyde, Phenformin
I-sopropyl Alcohol, Isoniazid ,Infection
L-actic Acidosis
E-thylene Glycol, ethyl alcohol
R-habdomyolysis
S-alicylates
O-ther Causes: Hyperalbuminemia, administered anions
