Table 2. Laboratory tests to evaluate the patient’s diabetes.
| Degree of glycemic control | Insulin secretion test | Auto-antibodies | ||||||
|---|---|---|---|---|---|---|---|---|
| Parameters | Referencea | Results | Parameters | Referencea | Results | Parameters | Referencea | Results |
| Glycated hemoglobin | Glucose | 72–99 mg/dL | 134 | GAD Ab | 0–1 U/mL | < 0.70 | ||
| NGSP | 4.0–6.0% | 8.5 | C-peptide | 0.48–3.3 ng/dL | 3.1 | |||
| eAG | 68–126 mg/dL | 197 | Glucose (post) | 90–126 mg/dL | 249 | |||
| Glycoalbumin | 11–16% | 21.3 | C-peptide (post) | N/A | 5.5 | |||
NGSP = National Glycohemoglobin Standardization Program, eAG = estimated average glucose, GAD = glutamic acid decarboxylase, Ab = antibody, N/A = not available.
aReference values are affected by many variables, including the patient population and the laboratory methods used. The ranges used at Yeouido St. Mary’s Hospital are for adults who do not have medical conditions that could affect the results.
