Abstract Objective: No single test of amniotic fluid has yet been found completely reliable, easily performed and universally applicable in the prediction of fetal pulmonary maturity. Setting: Department of obstetrics and gynecology of a university hospital. Method: The tap test and shake test were compared to the phosphatidylglycerol (PG) on amniotic fluid samples in 180 fetuses. Results: We found that the tap test results were correlated to the absence or presence of the respiratory distress syndrome in the newborn. When the tap test was evaluated at 5 min, the sensitivity (80.00%), specificity (91.03%) and predictive value for maturity (94.96%) and immaturity (68.29%) were comparable to those of the PG, which has a sensitivity of 82.85%, specificity of 92.41% and predictive value for maturity of 95.71% and immaturity of 72.50%. Conclusion: Our findings suggest that the tap test can be a valuable clinical procedure.
