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.
Anion Gap (Blood) Does this test have other names? Serum anion gap What is this test? This test looks at electrically charged particles in your blood. This helps your healthcare provider diagnose acid-base problems. The test results are done using the results of an electrolyte panel, another blood test.
The anion gap is the quantity difference between cations (positively charged ions) and anions (negatively charged ions) in serum, plasma, or urine. The magnitude of this difference (i.e., "gap") in the serum is calculated to identify metabolic acidosis. If the gap is greater than normal, then high anion gap metabolic acidosis is diagnosed.
An anion gap blood test is a way to check the acid-base balance (pH balance) of your blood. It tells you if your blood is too acidic or not acidic enough. The test uses the results of another blood test called an electrolyte panel .
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
