- Glycosylated hemoglobin (HbA1c) - to modify an achievement a marker of the average blood glucose level more than the growth 2-3 months
- Oral glucose tolerance breakdown (OGTT) - a test used less frequently that measures levels previously and 2 hours after absorbing a sweet beverage (concentrated glucose unconditional).
