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.
