OBJECTIVES: compare two gestational diabetes tests. METHODS: a prospective study in which 356 pregnant women, with no previous diabetes mellitus diagnoses independently submitted to two tests; fasting glycemia and risk factor association (FG+RF) and the simplified oral test for glucose tolerance (TTG50g). Methods of comparison were performed by sensitivity (S) and (ES) specificity indexes, positive predictive values (PPV) and negative predictive values (NPV), false results, false positive (FP) and false negative (FN) and by the difference of the results determined and expected, evaluated through the Chi-Square Test (p<0.05). RESULTS: FG+RF association determined diagnostic confirmation in a larger number of patients (187; 52.5%) than TTG50g (49; 13.8%). This difference was significant (p<0.05). The FG+RF association indicated a sensitivity of 83.7% and negative predictive value (NPV) of 95.3% as compared to TTG50g. CONCLUSIONS: the high sensitivity rates and NPV from the association of FG+RF as compared to TTG50g and its simplicity, practicality, low cost and easy replication are positive qualities for gestational diabetes testing indication.
