- Diabetes - Definition and Classification
- Types of diabetes (Type 1, Type 2, gestational, MODY, secondary diabetes)
- Epidemiology and global burden of disease
- Diagnostic Criteria (ADA / WHO standards)
- Fasting plasma glucose (FPG)
- Oral glucose tolerance test (OGTT)
- HbA1c levels
- Random plasma glucose with symptoms
- Repeat testing and diagnostic confirmation
