Using the results of the comprehensive metabolic panel (CMP), the anion gap is the difference between measured cations (positively charged ions like Na+ and K+) and measured anions (negatively charged ions like Cl- and HCO3-). There are three types: serum, plasma, and urine anion gaps. Normal anion gap readings range from 3–10 milliequivalents per liter. Readings outside this range may indicate a pH imbalance, and this can stem from a wide variety of health issues. Having an U6CfzF9.
