Evaluation of New Method for Measuring Stool Consistency

The subjects collect stool samples to be used for validation of a new direct measurement of stool consistency. Every stool sample produced during 2 collection periods of approximately 60 hours each have to be collected using the Commode Specimen Collection System (Medline Industries, Inc.). Each collection period starts preferably in the evening (20h00) and ends 3 days later in the morning (08h00). The collected samples must be stored at subject's home in a refrigerator provided by the sponsor until handover to the site staff.
