Really gross and possibly TMI question

Alright, so with my consistent intestinal problems (not celiac or lactose intolerance) my GI doc wants me to have a "fecal fat qualitative" done. I have to (ugh) poop into something and then get my poop into one of their urinary cups, FREEZE IT (gross as that sounds, I guess it’s better than just leaving it around, huh?) and bring it in the next day when I go for bloodwork.

So… I did that. I was lucky enough to do it while my husband was napping because he’s SO UNCOMFORTABLE about this that he’s teasing me relentlessly (he’s 32 going on 7). But they need about 1/2 cup, I filled about 1/3. I have another one of those urinary cups.

Choice: Next time I have to poop (part of the problem is that I poop now the way I peed before diagnosis!) should I just try to fill the second cup? Or should I just bring it in tomorrow and let them tell me it’s not enough (it actually may be enough, I don’t know!), and I’ll do it again tomorrow instead? (For note, I’m off of school this week and the place is not even 15 mins away, so it’s not a horrible hassle to do option #2)

I think half of this post is simply the desire to rant about the EEEEEEEEEEEEEEEEEEEEEEEEEWWWWWWWWWWWW factor of all of this! I like to laugh with my doctors that I have no more capacity for medical humiliation, but this kind of is humiliating — to have my feces examined like I’m a dog with worms 🙁

Oh, and my doc thinks this all might be due to failing pancreatic enzymes! Apparently, my pancreas will not be happy until it really is just a blob of totally useless cells floating in my abdomen, living a totally non-stressed life on my dime.
