Referring to the manufacturer recommended reference values [15,16,27,35], of note are slightly increased levels of PGI that exceed the upper cut-off (160 μg/L) in the “normal” and “Hp-gastritis” categories, and the levels of G-17b that are clearly higher than expected (normal range: 1–7 pmol/L), in these two categories [15,35]. This evidence concerns the gene HP and gastritis.
