Brief Summary:
The purpose of this study is to estimate the number of pregnant women who, during pregnancy, have low levels of the vitamin biotin. The hypothesis of this study is that a large number of pregnant women will have low biotin levels. This information will be used to later determine if low biotin levels during pregnancy cause certain birth defects.
