Anion Gapmmol/L
The anion gap is calculated from electrolytes and helps characterise acid-base balance.

What Anion Gap measures
The anion gap is calculated from electrolytes and helps characterise acid-base balance.
If your Anion Gap is low
A lower anion gap is uncommon and often related to a low albumin or a calculation artefact.
Commonly associated with
- Low albumin
- Laboratory artefact
If your Anion Gap is high
A higher anion gap points to extra acids in the blood and is usually interpreted with the other electrolytes and kidney tests.
Commonly associated with
- Kidney function
- Dehydration
- Certain medications or toxins
- Uncontrolled blood glucose
Typical reference range
| Group | Typical range |
|---|---|
| Adults | 5 – 15 mmol/L |
Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.
If it is within range
Your anion gap is within the typical range.
