Can there be false negative for pylori for both stool test and biopsy?
Was sure I had h. pylori. Did an endoscopy. I did have minor ulcers and redness in the esophagus, but biopsy showed no h. pylori. Doctor then ordered a stool test, and it also came back negative.
I was taking virgin coconut oil at the time which is a natural remedy that kills h. pylori. The coconut oil really works in reducing the symptoms but doesn't completely eliminate it. Could the coconut oil give me false negatives for both the biopsy and stool test?
Should I push for a blood test for h. pylori? I know it's not accurate because if it comes back positive, it just shows I have pylori sometime in the past. But if it comes back negative, I would have peace of mind that it's not caused by h. pylori. I don't believe my GI doctor has the equipment for the breath test.
