How to use

Call with the inputs below. Boolean inputs are optional (absent = false). Returns the value, an interpretation, and a breakdown. Deterministic — no network call.

Parameters

Name	Type		Description
sodium	number	required	Serum sodium — unit: mEq/L
chloride	number	required	Serum chloride — unit: mEq/L
bicarbonate	number	required	Serum bicarbonate (HCO3) — unit: mEq/L
albumin_g_dl	number	optional	Albumin (optional, for correction) — unit: g/dL

Example input

{
  "sodium": 140,
  "chloride": 100,
  "bicarbonate": 14,
  "albumin_g_dl": 3
}

Example output

{
  "calculator": "Anion Gap",
  "category": "General",
  "value": "26 mEq/L",
  "interpretation": "Elevated (consider HAGMA: MUDPILES/GOLDMARK)",
  "severity": "high",
  "detail": {
    "Anion gap": "26 mEq/L",
    "Albumin-corrected": "28.5 mEq/L"
  }
}
