Thanks for the explanation pb4
interesting info.
BumTum, don't worry about
this test at all! It's done in the privacy of your own home and nobody touches or even looks at your butt
in my mind, it's one of the easiest and most dignified tests we get! Lol (what a cruel life we live when pooping in a plastic cap and putting it in a jar to later hand to a stranger is on the "dignified" list, heeheehee)
