A combination of tests and clinical factors helps to rule out type 1 or type 2 diabetes and identify MODY or neonatal diabetes.
Blood tests measure glucose levels. It is also possible to measure how much insulin the body is producing. They might also check for autoantibodies, which suggest type 1 diabetes. In type 1 diabetes, autoantibodies mistakenly attack the body’s own insulin producing cells, i.e. the beta-cells, in the pancreas.
- Clinical evaluation to detect a combination of factors suggestive of monogenic diabetes:
- Diagnosis in the first six months of life
- Family history of diabetes
- Specific conditions that can be linked to specific genetic mutations
- Not being obese
- Belonging to specific ethnic groups
- Genetic testing using a blood sample.
