How to prepare
- Container. Get a sterile container from a pharmacy or the lab. For stool, choose one with a small spoon in the lid.
- Antibiotics. It is better to do the test before starting antibiotics. If you already take them, do not stop on your own. Tell your doctor.
- Collection. Collect stool from a clean surface, not from the toilet. Laxatives and suppositories are usually not used before collection. Ask your doctor.

Common questions
Why do results take so long?
The germs first have to grow in the lab. That takes several days.
Can I collect stool in the evening and bring it in the morning?
Fresh stool is usually needed. If there is no other way, ask the lab how to store it.
