Pregnant women attending the labor and delivery unit of the hospital or emergency clinic and reporting unidentified wetness (undetermined whether this is amniotic fluid leakage or urinary incontinence) will be enrolled in this study. After informed consent is obtained, each subject will be given a single AL-SENSE to use up to 12 hours or until the perception of wetness.\n\nProduct Usage\n\nAfter usage, the subject will read and record any occurrence of color change of the AL-SENSE 10 minutes after the liner removal and to mark if it changes color to blue or to green or not on the designated form. The subjects will fill out the questionnaire regarding the product usage experience and the liner color reading with no help from the investigator, to validate IFU reading comprehension. A blinded clinician will perform a "standard clinical diagnosis" (clinical assessment). The standard clinical diagnostic methods will include the following tests: (1) Pooling test, (2) Ferning test, (3) pH test by pH paper. A positive Pooling test and/or positive results in both the pH test and the Ferning test will be defined as a positive clinical test result.', 'detailedDescription': 'This study is designed to demonstrate that the performance of the AL-SENSE developed by Common Sense Ltd. is safe and effective and can be used to indicate if the patient may be experiencing an amniotic fluid leakage .\n\nThe AL-SENSE is an extended shelf-life product that is technically simple, fast to react, visually readable, and therefore enables women to test the cause of any unidentified wetness, before confirmation by a physician.\n\nPrinciples of operation:\n\nVaginal fluids are discharged over time and collected on the non-intrusive panty liner. If the user observes a blue or green stain, the result of the test is positive. The AL-SENSE polymer matrix is stained by blue or green color on a pale yellow background when the pH level of the fluid in contact with it is greater than the cutoff value.\n\nThe AL-SENSE will indicate that the pH level is elevated when the level is equal or greater than 6.5. This choice of 6.5 units as the cutoff level will limit the cases of false positive and will reduce unnecessary alarm.\n\nSummary of Study Design\n\nDesign: Prospective open-label, comparative pivotal study with comparison of self-assessments with blinded investigator assessments.\n\nPatient Population: Pregnant women, ages 18 and above.\n\nBaseline/ Screening\n\nSubjects attending the labor and delivery unit of the hospital or emergency clinic and reporting unidentified wetness (undetermined whether this is amniotic fluid leakage or urinary incontinence) will be enrolled in this study. After informed consent is obtained, each subject will be given a single AL-SENSE to use up to 12 hours or until the perception of wetness. The clinician will explain the proper use and handling of the AL-SENSE and how to read the result. The participants will be provided with instructions for use and also directed to read the Instructions For Use (IFU) prior to applying the AL-SENSE pad.\n\nProduct Usage\n\nAfter usage, the subject will read and record any occurrence of color change of the AL-SENSE 10 minutes after the liner removal . The subjects will fill out the questionnaire regarding the product usage experience and the liner color reading with no help from the investigator, to validate IFU reading comprehension.\n\nClinical Diagnosis\n\nA blinded clinician will perform a "standard clinical diagnosis" (clinical assessment), and record the results on a worksheet to be included in the case report form. The standard clinical diagnostic methods will include the following tests: (1) Pooling test, (2) Ferning test, (3) pH test by pH paper.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT'], 'maximumAge': '50 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\nScreening/ Baseline inclusion criteria for subject participation in the study at baseline assessment are pregnant women age 18 and above who have completed minimum 16 weeks of pregnancy are eligible for the study.
