Tolerance test
For fasting blood glucose normal or slightly high occasional diabetes or diabetes in patients with suspected (if positive family history, or repeated miscarriage, premature birth, stillbirth, giant baby, childbirth, abortion by mothers, or repeated fat furuncle carbuncle swollen sores, etc.) need to be carried out glucose tolerance test. However, fasting blood glucose increased significantly while heavy dominant cases the diagnosis has been able to establish that a large number of glucose could increase the burden should be exemption.

OGTT (oral glucose tolerance test, OGTT)
The most commonly used, in the past, adult one-100g, in recent years, WHO proposed to use 75g (or whether adult or child per kg weight 1.75g, the total amount of not more than 75g) oral law. In oral glucose before and after 1 / 2, 1,2,3-hour blood samples measured sugar, urine specimens collected at the same time check urine sugar.

Results: The normal (age 15 ~ 50 years old) fasting blood glucose for 70 ~ 100mg/dl (glucose oxidase enzymes really sugar Law), sugar absorption peak at 30 ~ 60 minutes (more than 50 years of age after the shift), there is generally no more than 170mg/dl, 2 hPG concentration of the restoration of the normal range, three hours can be reduced to below normal. Negative urine sugar. 100g and 75g law is not very different compared to only the latter an early return to normal blood sugar. Impaired glucose tolerance over 50 years of age tend to reduce the physiological, in 1 hour and higher peak every 10-year-old increase in blood sugar 10mg/dl.
