Pregnant Subjects
These are pregnant women that are admitted to Labor \&Delivery (L\&D) or an outpatient in the Women's Health Clinic that are being evaluated for rupture of membranes. PAMG-1 immunoassay: The procedure includes the insertion of a PAMG-1 swab into the subject's vaginal vault without a speculum for one minute. Once the swab is obtained, the treating physician will place the swab in a solvent vial for one minute. A developing strip is then placed in a vial and allowed to develop for five minutes. The results are read from the developing strip.
Pregnant Controls
These women will be found primarily in the Women's Health Clinic, when being seen for their routine antepartum appointments. Most of them will be recruited at about 36 weeks, since they will be having a pelvic exam at this time, as part of their routine antepartum care.

Non Pregnant Controls
These women will be found in the Women's Health Clinic, when being seen for gynecology appointments. Nursing staff and the dashboard will help to identify those patients who will be having a pelvic exam.
