Intravenous glucose tolerance test in gestational diabetes and pregnancy: 'manual' versus computerized assessment.
In order to assess the reliability of 'manual' versus computerized interpretation of the intravenous glucose tolerance test (IVGTT), fifty-five women, aged 19 to 41, underwent an IVGTT. Fifteen subjects had overt diabetes mellitus, sixteen were evaluated for gestational diabetes and twenty-four were healthy controls, fourteen of whom were pregnant. Each IVGTT was analysed by two trained physicians independently and by a simple computerized program, and the k' values obtained were compared, using the Student t-test for paired data. Significant difference (p less than 0.005) was found comparing either the 'manual' assessments or the 'manual' versus computer calculations. It is concluded that the IVGTT test must be interpreted using a simple computerized program, especially in borderline cases of pregnancy where the traditional 'manual' analysis might result in misclassification or misdiagnosis of the patient.
