Biochem/physiol Actions
Studies show that smoking has an effect on the level of pepsinogen I present in serum in a H. pylori-dependent manner. Patients with lower titer levels had higher levels of pepsinogen I.
Used as a control in ELISA.

Serum pepsinogen (sPG) levels are used in gastric cancer screening programs. However, modification of sPG levels by smoking habit, according to the status of Helicobacter pylori (H. pylori) infection has been little investigated. This study investigated the effects of smoking
