What Is an Anion Gap? The anion gap test measures anion gap (sometimes called serum anion gap) or how much acid is in your blood. Acid levels that are higher or lower than normal can tip your doctor ...

The anion gap blood test measures the acid-base and electrolyte balance in the blood. Results can show whether there is an imbalance in a person’s pH levels, which may be making the blood too acidic ...

Your anion gap is more than just a lab number—it’s a window into your body’s acid–base balance and overall metabolic health. Understanding how it’s calculated, what’s normal for your lab, and how to ...

Background: In vitro data suggest that lower extracellular pH activates the immune system. We conducted a population-based study of the relation between serum acid–base status and inflammation.
