How should I get ready for the test?
Before giving a stool sample, tell the healthcare worker if you have diarrhea or are using antibiotics, barium, bismuth, oil, iron, magnesium, or medication to stop diarrhea.
Ask your healthcare worker if changes to your diet are necessary before stool samples are collected for this test.
