Stool Collection FAQs

What, exactly, do I have to do?

Instructions are provided with each kit. Or you can click here for stool collection instructions.

Why do I have two tubes to fill, one with liquid and one without? How much should I fill each one?

The tubes are different because your doctor wants us to run different tests. The tube with the blue top and the scoop should be no more than half filled. For the tube with the liquid use the swab to obtain a small sample of stool. The swab is then placed into the tube with the liquid and the cap is secured tightly on the tube. Do NOT use the swab more than one time. Only a small amount is needed for testing.

When will you get my stool sample?

Stool samples are sent priority overnight, so we will receive it the next day.

How long will my stool last, in case I get it in the tubes but can’t sent it right away?

Fresh stool (in tube without liquid) must be sent to the lab within 24 hours. Stool samples in the tube with liquid may be kept at room temperature for up to 4 days. The sooner you send it the better.

I accidentally got urine (or menstrual blood) mixed into my stool sample. Is it still okay to use?

Preferably not, it is best if a stool sample is not compromised by water, blood, or urine. Try to take specimen from an area on the collection device that hasn’t been contaminated.

My paper collection device fell into the toilet. Can I still send the sample?

No. The toilet might have contaminated the sample. It is best if a stool sample is not compromised by water, blood, or urine.

I only went enough to fill one sample tube. Can the samples come from different bowel movements?

Yes, they can.
