Patient Preparation: | This test requires the adult patient (>17 years of age) to fast and abstain from smoking for 1 hour prior to test administration. The patient should not have taken antibiotics, proton pump inhibitors (e.g., Prilosec, Prevacid, Aciphex, Nexium) or bismuth preparations (e.g., Pepto-Bismol) within the previous 14 days. The effect of histamine 2-receptor antogonists (e.g., Axid, Pepcid, Tagamet, Zantac) may reduce urease activity on urea breath tests and should be discontinued for 24-48 hours before the sample is collected. When used to monitor treatment, the test should be performed four weeks after cessation of definitive therapy. The patient should be informed that the Pranactin-Citric drink that will be administered contains phenylalanine. Phenylketourics restrict dietary phenylalanine. |
Causes for Rejection: | Underinflated bags. Specimens from patients younger than 18 years of age. Refrigerated or frozen samples. |
