When used for classifying pregnant patients as normal or abnormal in terms of carbohydrate intolerance, the k value computed from a two-sample intravenous glucose tolerance test (IVGTT) (10 and 60 minutes) is reliable except in a zone of +/- 0.10 k points from the appropriate lower limit of normal. Retesting with six samples obtained in one hour may be required for patients with values within the doubtful range, +/- 0.10 of the lower limit of normal. Considerable savings can be realized nevertheless with the use of this test as compared with doing a full, seven-sample test on each subject. Our results suggest that the abbreviated IVGTT be used more widely as a routine screening procedure for diabetes rather than being restricted to use on suspect populations. One can make a direct conversion of blood sugar readings into k with the use of a table presented in the paper.
当用于根据碳水化合物不耐受情况将孕妇分类为正常或异常时，通过两样本静脉葡萄糖耐量试验（IVGTT）（10分钟和60分钟）计算出的k值是可靠的，但在距正常下限±0.10 k点的范围内除外。对于k值在可疑范围内（正常下限±0.10）的患者，可能需要在一小时内采集六个样本进行重新检测。不过，与对每个受试者进行完整的七样本检测相比，使用此检测方法仍可实现大量节省。我们的结果表明，简化的IVGTT应更广泛地用作糖尿病的常规筛查程序，而不仅限于在可疑人群中使用。使用本文提供的表格，可以将血糖读数直接转换为k值。
