The ADA guidelines for testing children for T2DM depend on whether a child is overweight or at risk for being overweight.[4] This should be determined by checking height and weight or their growth charts to calculate the BMI; if their body weight is >120% of ideal for height or if their BMI is >85^th percentile for age or gender, they should be assessed for the presence of diabetes. In addition, they should be checked for any 2 of the following risk factors:

• a family history of T2DM in a first or second degree relative;
• race/ethnicity of American Indian, African American, Hispanic, Asian or Pacific Islander; 
• signs of insulin resistance, including hypertension, dyslipidemia, acanthosis nigricans, or polycystic ovarian syndrome.

If there is any index of suspicion, age of screening initially should be at 10 years of age (or the onset of puberty if puberty occurs at a younger age). The ADA recommends that the test should be conducted as a fasting plasma glucose test and repeated every 2 years if the child continues to be at risk. Harms D. J Nurse Pract. 2014; 00:00 – 00.
