Table 1 Laboratory findings on admission.
| Parameter | Reference range | On admission |
|---|---|---|
| Blood glucose (mmol/L) | 4.1–6.1 | |
| HbA1c (%) | 4.9–6.0 | |
| pH | 7.35–7.45 | |
| HCO (mmol/L) | 19.0–30.0 | |
| Base excess (mmol/L) | −6 to +6 | − |
| Lactate (mmol/L) | 0.4–2.2 | |
| Sodium (mmol/L) | 138–145 | |
| Potassium (mmol/L) | 3.6–4.8 | |
| Chloride (mmol/L) | 101–108 | |
| Creatinine (μmol/L) | 57–95 | |
| BUN (mmol/L) | 2.9–7.1 | |
| WBC count (×10/L) | 3.3–8.6 | |
| Hemoglobin (g/L) | 137–168 | |
| Hematocrit (%) | 40.7–50.1 | |
| Platelets (×10/L) | 158–348 | 198 |
| CK (U/L) | 59–248 | |
| Total bilirubin (μmol/L) | 7–26 | 10.0 |
| AST (U/L) | 13–30 | 19 |
| ALT (U/L) | 10–42 | 32 |
| Albumin (g/L) | 41–51 | 40 |
| ALT – alanine aminotransferase; AST – aspartate aminotransferase; BUN – blood urea nitrogen; CK – creatine kinase; WBC – white blood cell. Reference ranges were based on institutional laboratory standards. Bold values indicate results outside the reference range. The serum sodium value shown is the measured value (139 mmol/L). When corrected for hyperglycemia, the corrected sodium was 159 mmol/L, which indicated severe hypernatremia. | ||
