Normal anion gap. A normal anion gap range is typically 4-12 mEq/L. That means your blood pH level is healthy and balanced. A neutral pH level is 7.0.
There’s no universal “normal” anion gap. Once you get your blood test results back, there will be information that indicates what that lab’s normal anion gap range is. There’s also a wide range of “normal” anion gap results depending on different factors.
Normal values are 3 to 11 mEq/L [4, 2]. Some older types of tests used different techniques to measure electrolytes, which give different results. The normal range for these older tests is 8 to 16 mEq/L [5, 6, 7]. It’s important to note that a number of factors may cause a high anion gap.
The normal anion gap depends on serum phosphate and serum albumin concentrations; An elevated anion gap strongly suggests the presence of a metabolic acidosis; The normal anion gap varies with different assays, but is typically 4 to 12mmol/L (if measured by ion selective electrode; 8 to 16 if measured by older technique of flame photometry)
For reference, a normal anion gap depends on the concentration of phosphate and albumin in the serum and ranges from 4 to 12 mmol/L. An increased or normal anion gap metabolic acidosis is typically due to excess acid and/or decreased base.
Healthy subjects typically have a gap of 0 to slightly normal (< 10 mEq/L). A urine anion gap of more than 20 mEq/L is seen in metabolic acidosis when the kidneys are unable to excrete...
Normal results are 4 to 12 mEq/L, although the normal level may vary from by lab. If your results are higher, it may mean that you have metabolic acidosis. Hypoalbuminemia means you have less albumin protein than normal.
The anion gap measures the difference—or gap—between the negatively charged and positively charged electrolytes in your blood. If the anion gap is too high, your blood is more acidic than normal. If the anion gap is too low, your blood isn't acidic enough.
A normal anion gap of 8 - 16 suggests that there is loss of bicarbonate as the cause of the patient's acidosis, either renally or due to GI loss. An elevated anion gap of >16 suggests that there is an excess of acid within the blood, causing an acidosis.
Normal blood contains electrically charged particles. An anion gap is a difference between the positively charged particles and the negatively charged particles, called cations (sodium Na+ and potassium K+) and anions (chloride Cl- and bicarbonate HCO3-). These charged particles contribute to a blood’s pH.
