Tests and diagnosisBy Mayo Clinic staff
If you experience diabetic hyperosmolar syndrome, prompt diagnosis is critical. The emergency medical team will do a physical exam and may ask those who are with you about your medical history.
You may need various lab tests to measure:
- Your current blood sugar level
- Glycated hemoglobin (A1C) — a blood test that indicates your average blood sugar level for the past two to three months
- Whether or not ketones are present in your urine — ketones are byproducts made when fat is used as fuel instead of glucose
- Your kidney function, by testing the amount of blood urea nitrogen or creatinine in your blood
- The amount of potassium, phosphate and sodium in your blood
You'll be diagnosed with diabetic hyperosmolar syndrome if your blood sugar level is 600 mg/dL (33.3 mmol/L) or higher.
