eTable 2. Laboratory values in the range of increased diabetes risk (2).
| Laboratory values in the range of increased risk forthe development of diabetes (modified from [18]) | |
| Impaired fasting plasma glucose (IFG) | 100–125 mg/dL or 5.6–6.9 mmol/L*1 |
| HbA1c value | 5.7 to < 6.5 % or 39 to < 48 mmol/mol*2 |
| Impaired glucose tolerance (IGT) (in the oral glucosetolerance test, 75 g) | FPG: < 126 mg/dl or < 7.0 mmol/l 2-hour plasma glucose: 140–199 mg/dL or 7.8–11.0 mmol/L*1 |
*1 WHO cut-off values: 110–125 mg/dL (6.1–6.9 mmol/L), the German College of General Practitioners and Family Physicians (Deutsche Gesellschaft für Allgemeinmedizin und Familienmedizin, DEGAM), the Drug Commission of the German Medical Association (Arzneimittelkommission der deutschen Ärzteschaft, AkdÄ), the German Society of Wound Healing and Wound Treatment (Deutsche Gesellschaft für Wundheilung und Wundbehandlung, DGfW), and the German Society of Nursing Science (Deutsche Gesellschaft für Pflegewissenschaft, DGP) support the WHO cut-off values for FPG (see also eTable 1). The DEGAM, the AkdÄ, the DGfW, and the DGP do not consider the oGTT, and thus impaired glucose tolerance, to be of value in the primary care setting
*2 For special features/influencing factors (e.g., age), see long version of the NDMG (www.leitlinien.de/diabetes)
HbA1c, hemoglobin A1c; oGTT, oral glucose tolerance test; FPG, fasting plasma glucose
