The indications for and results of all glucose tolerance tests (GTTs) performed at the Antenatal Clinic, Groote Schuur Hospital, Cape Town, over a period of 1 year, and the indications for a GTT in the first 80 newly diagnosed diabetics over a 4-year period are analysed. Out of 558 GTTs, only 17 tentative diagnoses of 'gestational diabetes' were made. The most rewarding single indication for a GTT was repeated glycosuria, which was an indication in 61 out of the 80 newly diagnosed diabetics. A combination of two indications in the same patient was related to twice as many abnormal GTTs as a single indication, while reported previous diabetes or hyperglycaemia certainly merited confirmation. Reasons for repeating GTTs are discussed, as well as the management of 'borderline' and 'potential' diabetics. It is emphasized that 'diabetes' or 'hyperglycaemia' diagnosed during pregnancy is not equivalent to a definite diagnosis of diabetes in the non-pregnant state.
对开普敦格罗特·舒尔医院产前诊所1年内进行的所有葡萄糖耐量试验（GTT）的指征和结果，以及4年内最初80例新诊断糖尿病患者进行GTT的指征进行了分析。在558次GTT中，仅做出了17例“妊娠期糖尿病”的初步诊断。进行GTT最有价值的单一指征是反复出现糖尿，这是80例新诊断糖尿病患者中61例的指征。同一患者出现两种指征时GTT异常的数量是单一指征时的两倍，而既往报告的糖尿病或高血糖肯定值得进一步确认。文中讨论了重复进行GTT的原因，以及“临界”和“潜在”糖尿病患者的管理。强调孕期诊断的“糖尿病”或“高血糖”并不等同于非孕期明确诊断的糖尿病。
