10 Grams unpreserved stool. Refrigerate. To avoid false negative results, no antibiotics, proton pump inhibitors, or bismuth preparation should be administered to patients for 14 days prior to sample collection. Note: Common bismuth and proton pump inhibitors include the following: bismuth: pepto-bismol, kaopectate, pink bismuth. Proton pump inhibitors: nexium, prevacid, zegerid and prilosec. Current medical practice recommends that assessment of eradication by any diagnostic method should be done at least 4 weeks following completion of therapy. Performance characteristics have not been established in asymptomatic populations. Performance characteristics have not been evaluated in pediatric population.
