NCT00613977

Brief Summary

The investigators wish to compare the difference in both cost and time to result for determining fetal lung maturity for the Lamellar Body Count method and the Fetal Lung Maturity II. Our hypothesis is that the time to result will be significantly less using the Lamellar Body Count method, and the cost associated with this method over the traditional FLM II will be favorable.

Study Population

Women delivering a term infant by cesarean section at Oklahoma State University Medical Center.

You may qualify if:

  • Term intrauterine gestations beyond 37 completed weeks with dating calculated by their sure last menstrual period (LMP) using Negel's rule or utilizing a first trimester crown rump length ultrasound.
  • Women with a previous C/S scheduled for repeat C/S.
  • Women who are undergoing a scheduled C-Section for malpresentation

You may not qualify if:

  • Presence of gross blood in amniotic sample
  • Hematocrit count greater than 1% on ADVIA 2120
  • Presence of meconium in sample
  • Patients with oligohydramnios defined as an amniotic fluid index of less than 5 cm or polyhydramnios defined as an amniotic fluid index of more than 24 cm.
