To report our experience in the prediction of fetal lung maturity with the tap test.
Amniotic fluid was obtained from 207 pregnant women from 17-40 weeks' gestation and the tap test compared with the phospholipid profile.
The predictive values for a mature tap test were 100%, 99.9% and 98.2% and for immature tap test were 45.8%, 50% and 56.4% at 2.5 and 10 min, respectively.
The tap test is a reliable, rapid, easy, inexpensive and accurate method for detection of fetal lung maturity.
