Anion gap

Delta-delta (ΔΔ) value

Delta-Delta value is used to determine whether there is an additional metabolic acid-base disturbance or not.
Delta-Delta (ΔΔ) = Delta anion gap (ΔAG) / Delta bicarbonate (ΔHCO3)
- Delta anion gap (ΔAG) = Calculated anion gap - Expected anion gap
  - Calculated anion gap = [Na⁺] - [Cl^-] - [HCO₃^-]
  - Expected anion gap = 2.5 x serum albumin level
- Delta bicarbonate (ΔHCO₃) = 24 - serum bicarbonate level
