As a user, I found the collection process for the gut zoomer test to be potentially prone to errors. I suggest including a sanitary mat in the kit to place the collection bag on a flat surface. This would prevent the bag from falling into the toilet and ruining the sample collection. Sterile gloves would also be beneficial, as well as additional toilet collection bags to account for any human error. Alcohol wipes could be used to clean the collection tubes and the surface where the sample was collected. As a chemist, I was able to navigate this process, but I believe these improvements would make it more user-friendly and foolproof.
