Serum Anion Gap | Md Nexus

Clinical Utility: calculation of the anion gap is useful to differentiate anion gap metabolic acidoses (AGMA) (see Metabolic Acidosis-Elevated Anion Gap , [[Metabolic Acidosis-Elevated Anion Gap]]) from non-anion gap metabolic acidoses (NAGMA) (see Metabolic Acidosis-Normal Anion Gap , [[Metabolic Acidosis-Normal Anion Gap]]) Anion gap reflects the difference between unmeasured anions (i.e. the anions in the blood that are not routinely measured) unmeasured cations Normal Anion Gap Values: laboratory-dependent (so the laboratory should publish their normal range) Correction of Anion Gap for Serum Albumin: since albumin represents the major unmeasured anion responsible for the anion gap (with a net negative charge at physiologic pH), the expected anion gap must be corrected for serum albumin Anion Gap Decreases 2.3-2.5 mEq/L for Each 1 g/dL Decrease in the Serum Albumin: Corrected Anion Gap = (Measured Anion Gap) + [2.5 x (4.5 Serum Albumin)] Correction of Anion Gap for Hyperkalemia: since potassium is an unmeasured cation For example, serum potassium of 6.0 mEq/L will decrease the anion gap by 2 mEq/L Correction of Anion Gap for Hypercalcemia: since calcium is an unmeasured cation Continue reading >>

    Here is the formula for anion gap:
    Agap = Na + K - Cl -CO2
    I would think that the doctor would be monitoring the glucose level (not the agap) to determine when to stop the insulin drip. Anyone else have an idea?
