D. Kassanos et al., THE TAP TEST - A SIMPLE AND INEXPENSIVE METHOD FOR THE DIAGNOSIS OF FETAL PULMONARY MATURITY, International journal of gynaecology and obstetrics, 41(2), 1993, pp. 135-138
OBJECTIVE: To report our experience in the prediction of fetal lung ma
turity with the tap test. METHOD: 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 ma
ture tap test were 100%, 99.9% and 98.2% and for immature tap test wer
e 45.8%, 50% and 56.4% at 2.5 and 10 min, respectively. CONCLUSION: Th
e tap test is a reliable, rapid, easy, inexpensive and accurate method
for detection of fetal lung maturity.
