In mild DKA, anion gap is greater than 10 and in moderate or severe DKA the anion gap is greater than 12. These figures differentiate DKA from HHS where blood glucose is greater than 600 mg/dL but pH is greater than 7.3 and serum bicarbonate greater than 15 mEq/L.In DKA, bicarbonate is replaced by β-hydroxybutyric acid and acetoacetic acid, so that the sum of bicarbonate and chloride concentrations is reduced and the anion gap is thus increased.Diabetic ketoacidosis (DKA) is a serious life-threatening complication of diabetes mellitus characterized with high anion gap metabolic acidosis due to excessive production of ketoacids at an expense of reduced serum bicarbonate concentration [1].
Why is anion gap high in DKA?
In DKA, bicarbonate is replaced by β-hydroxybutyric acid and acetoacetic acid, so that the sum of bicarbonate and chloride concentrations is reduced and the anion gap is thus increased.
Is anion gap high or low in DKA?
Diabetic ketoacidosis (DKA) is a serious life-threatening complication of diabetes mellitus characterized with high anion gap metabolic acidosis due to excessive production of ketoacids at an expense of reduced serum bicarbonate concentration [1].

When is the anion gap closed in DKA?
DKA is resolved when 1) plasma glucose is <200–250 mg/dL; 2) serum bicarbonate concentration is ≥15 mEq/L; 3) venous blood pH is >7.3; and 4) anion gap is ≤12. In general, resolution of hyperglycemia, normalization of bicarbonate level, and closure of anion gap is sufficient to stop insulin infusion.
What lab values are consistent with DKA?
Overview. Laboratory findings consistent with the diagnosis of diabetic ketoacidosis (DKA) include blood pH < 7.3, serum bicarbonate < 18 mEq/L, anion gap > 10 mEq/L and increased serum osmolarity.
What are the three criteria for DKA?
Three key features of diabetic acidosis are hyperglycemia, ketosis, and acidosis. The conditions that cause these metabolic abnormalities overlap.
How do you assess DKA?
- A simple urine test that involves peeing on a Ketostix or dipping the Ketostix into a cup of urine, and observing the color change on the strip. …
- A blood test can be done with special ketone test strips.
What type of acidosis is DKA?
Diabetic acidosis (also called diabetic ketoacidosis and DKA) develops when substances called ketone bodies (which are acidic) build up during uncontrolled diabetes. Hyperchloremic acidosis is caused by the loss of too much sodium bicarbonate from the body, which can happen with severe diarrhea.

What does an anion gap of 6 mean?
The anion gap tells you if your electrolytes are unbalanced, which can cause changes in the acid levels in the blood. An anion gap result can be low, normal, or high. A low anion gap (less than 6 mEq/L) may indicate: Low levels of albumin in the blood (hypoalbuminemia)
What is anion gap high?
If your blood test results show a high anion gap, you may have acidosis. This means you may have a higher-than-normal level of acid in your blood (a lower-than-normal blood pH). Acidosis may be a sign of the following: Dehydration.
What is anion gap normal range?
Normal results are 3 to 10 mEq/L, although the normal level may vary from lab to lab. If your results are higher, it may mean that you have metabolic acidosis.
Can you have DKA without anion gap?
DKA patients often develop a non-anion-gap, hyperchloremic metabolic acidosis. This may occur due to gradual development of DKA with urinary excretion of ketoacid (which then cannot be converted to bicarbonate) and/or initial resuscitation with NS.
Is potassium low or high in DKA?
Patients in DKA are low in total body potassium and their serum concentration is falsely elevated due to extracellular shift. On average, patients will have a potassium deficit of 3-5 mEq/kg.

What ketone level is ketoacidosis?
Check your blood sugar and ketone levels
lower than 0.6mmol/L is a normal reading. 0.6 to 1.5mmol/L means you’re at a slightly increased risk of DKA and you should test again in 2 hours. 1.6 to 2.9mmol/L means you’re at an increased risk of DKA and should contact your diabetes team or GP as soon as possible.
Is co2 high or low in DKA?
This relationship states that the pH of blood is proportional to the ratio of bicarbonate concentration to partial pressure of carbon dioxide (pCO2). During DKA, pH is low primarily because the bicarbonate buffer is exhausted, i.e. bicarbonate concentration is reduced.
