Normal serum pepsinogen I levels in adults: A population‐based study with special reference to <i>Helicobacter pylori</i> infection and parietal cell antibodies

Abstract

Men had higher normal PG I values than women, but there was no significant variation by age. H. pylori infection was associated with elevated PG I levels and a small decrease with increasing age. Non-infected PCA-positive subjects showed the lowest mean PG I level.
