Anion Gap & Delta-Delta Calculator
Compute the serum anion gap with albumin correction, the delta-delta ratio, and bicarbonate gap. Detects HAGMA, NAGMA, and mixed acid-base disorders. Essential for ED, ICU, and nephrology.

★ DoctorScribe — Complete Clinic Management
From lab beep to acid-base diagnosis — automatic
DoctorScribe ingests every ABG and chem panel, flags HAGMA in real-time, ranks the MUDPILES differential by patient context (diabetic? on metformin? AKI?), and orders the right next test.
Clinical Disclaimer: The anion gap is highly dependent on albumin — always use the corrected formula (add 2.5 × (4 − albumin)). A 'normal' AG in a hypoalbuminaemic ICU patient may hide a major organic acidosis. The Δ/Δ is approximate; use ABG, urine AG, and the full clinical picture. Always verify against your local prescribing reference and apply clinical judgment.
Acid-base maths, done at the bedside
DoctorScribe auto-extracts Na, Cl, HCO₃, albumin from the lab feed (CLIA / Roche / Mindray integration), computes corrected AG and Δ/Δ ratio, and links the differential to your DKA, sepsis, methanol, or salicylate worksheets.
