A member asked:
Will zantac 150mg cause a false negative h. pylori stool lab result? if so, how long is waiting period before having stool lab for h. pylori?
A doctor has provided 1 answer
No : H pylori is a bacteria. Without antibiotics it will not be eradicated therefore just Zantac alone will not affect the test results.
