<prompt> Oral glucose tolerance test in children is done with1.5 gmkg glucose1.75 gmkg glucose2 gmkg glucose2.5 gmkg glucose  <response>: Ideal weight of the glucose taken for glucose tolerance test for children are 1.75gmkg glucose . Obtain a fasting blood sugar level, then administer an oral glucose load 2 gkg for children aged 3 y, 1.75 gkg for children aged 3-10 y , or 75 g for children aged 10 y. Check the blood glucose concentration again after 2 hours. A fasting whole-blood glucose level higher than 120 mgdL 6.7 mmolL or a 2-hour value higher than 200 mgdL 11 mmolL indicates diabetes. However, mild elevations may not indicate diabetes when the patient has no symptoms and no diabetes-related antibodies. Reference: GHAI Essential pediatrics, 8th edition
