Abstract
In the standard glucose tolerance test (SGTT), 100 g of glucose is administered after the fasting time of 14-15hours. In this study the fasting time was prolonged to 20 hours by omitting meals after 2 p.m.on the day before the tolerance test.
Comparative studies were carried out in 10 normal healthy subjects, 8 diabetic-borderline cases, 3 cases with renal glycosuria and 6 diabetic patients.
The results are as follows:
1.There was no significant difference in blood sugar tolerance curve changes between SGTT and HGTT performed in the normal subjects and in the diabetic patients.
2.Six of the 8 borderline cases diagnosed with SGTT showed a diabetic pattern in HGTT.Mean values of blood sugar levels at 90, 120 and 180 minutes after glucose ingestion were higher in HGTT than those in SGTT (p<0.05).
