Objective:
This study determined the reference interval of pepsinogen (PG) of healthy people in the local region to provide a basis for early screening of gastric cancer.
Methods:
Among the healthy people who underwent a physical examination in our hospital from January 2020 to December 2020, 2568 subjects were selected based on the relevant screening criteria. Their serum PG I and II levels and PG I:PG II ratio were determined by chemiluminescent microparticle immunoassay (CIMA), and the results were statistically analyzed. Finally, according to document CLSI-C28-A3, the PG reference interval of the local region was determined.
Results:
The PG I and II levels of the males in all age groups were higher than those of the females in the corresponding age groups, and the differences were statistically significant (P < 0.05). However, the differences in the PG I:PG II ratio between the genders in the different age groups were not statistically significant (P > 0.05). The PG I and II levels increased with age in both men and women, while the PG I:PG II ratio was not correlated with age in either gender.
Conclusion:
The PG reference interval of the local region was initially determined as providing a reliable reference basis for clinical treatment.
