I'm 22 years old, have had his for a while. Lately though, there have been red chunks and pieces in my stool. I thought maybe it's undigested food, but I took a picture and showed it to my doctor and he gave me a form to do a stool occult test, where I need to bring samples from 3 days of stool to the hospital lab. I'm quite frightened, and I have no idea how to do this.
Looking for people who have done this so I know how exactly I go about collecting these samples and transporting them.
