Diabetic ketoacidosis is a medical emergency in which insulin deficiency drives high glucose, ketone production and metabolic acidosis. This tool counts how many ADA-style biochemical criteria are present so the result can support an urgent conversation, but it cannot confirm or exclude the condition. Clinical assessment and laboratory testing remain essential.
Count ADA-style DKA criteria without making a diagnosis.
Criteria: glucose ≥ 250 mg/dL; pH < 7.30; bicarbonate < 18 mmol/L; beta-hydroxybutyrate ≥ 3.0 mmol/L or moderate/large urine ketones
The thresholds reflect commonly cited ADA-style biochemical criteria. They are flags, not a diagnosis. A normal value in one category does not rule out DKA, and the tool never suggests a treatment dose.
| Symbol | Meaning |
|---|---|
| glucose | Blood glucose in mg/dL. |
| pH | Venous or arterial pH from a blood gas. |
| bicarbonate | Serum bicarbonate in mmol/L. |
| ketones | Beta-hydroxybutyrate or urine ketone result. |
Glucose is at least 250, pH is below 7.30, bicarbonate is below 18, and beta-hydroxybutyrate is at least 3.0 with large urine ketones. All four criteria groups are met. That pattern is concerning for DKA and requires emergency assessment; the count itself is not a diagnosis.
DKA develops when insulin deficiency allows glucose to rise while the body breaks down fat for energy. The resulting ketones are acids, and their accumulation produces metabolic acidosis with dehydration and electrolyte shifts. The biochemical triad of hyperglycaemia, ketosis and acidosis is the basis for the criteria counted here, but the diagnosis is made by clinicians who can assess symptoms, hydration, breathing, mental status and laboratory trends. Counting criteria is useful for recognising a dangerous pattern quickly, yet it can miss atypical presentations such as euglycemic DKA or mixed acid-base disorders. It can also over-call a picture when another cause of acidosis is present. For that reason the result should never delay emergency care, and it should never be used to choose or calculate a treatment dose.

No. This tool counts biochemical flags and cannot diagnose. Diagnosis requires clinical assessment, confirmed laboratory values and exclusion of other causes of acidosis and ketosis.
These tools convert or screen laboratory values using published formulas. They do not diagnose diabetes, insulin resistance or ketoacidosis, and they do not calculate an insulin dose. Laboratory methods vary; confirm results with the reporting lab and a clinician. DKA symptoms need urgent medical care.
