The tap test: a simple and inexpensive method for the diagnosis of fetal pulmonary maturity.
OBJECTIVE
To report our experience in the prediction of fetal lung maturity with the tap test.


METHODS
Amniotic fluid was obtained from 207 pregnant women from 17-40 weeks' gestation and the tap test compared with the phospholipid profile.


RESULTS
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.


CONCLUSIONS
The tap test is a reliable, rapid, easy, inexpensive and accurate method for detection of fetal lung maturity.
