Stool tests won’t really show a bacteria overgrowth, hydrogen breathe tests are good because it shows exactly what bacteria is high. However, lots of false positives. Mine was seen in my nutrient deffociency test. It was bloodwork and urine showing the small intestines. Stool tests are pretty much colon related. Sibo isn’t the same as h pylori. H pylori is an infection that can be gotten rid of pretty with I think an antibiotic.
