HyStool is simple to use and as hygienic as possible. The patient simply attaches the HyStool bag to the toilet seat. There is no need to reach inside a potentially contaminated toilet bowl to fit it. They simply use the toilet as normal and collect a stool sample from the bag. The HyStool bag and contents are then simply flushed away. There is no need to retrieve anything from the toilet after use. Because HyStool is 100% water soluble it will safely flush away without causing any blockages.
