Background: At present, the pepsinogen reference values applicable to subjects from Gansu province have not been established. Therefore, the current study aimed to establish reference values for PGI, PGII, and the PGI/ PGII ratio in Gansu Province, Northwest China.
Methods: The present study was a cross-sectional study. Following screening in the physical examination center of Gansu Provincial Hospital, 2,130 healthy subjects were enrolled (age range 18 - 88 years; BMI range 15.35 - 38.89 kg/m2) from March 2018 to December 2020. Serum PGI and PG II concentration levels were detected by chemiluminescence. The reference values were defined according to age and gender by non-parametric 95th percentile intervals.
Results: The increase in age caused a gradual increase in the levels of PG I and PG II, while PG I/PG II ratio gradually decreased. The PG I, PG II and PG I/PG II ratio in males were significantly higher than those in females. The reference values for PG I, PG II and PG I/PG II ratio in males: < 40 years old were 22.79 - 119.79 ng/mL, 3.02 - 21.57 ng/mL, and 2.99 - 10.25, respectively; ≥ 40 years old were 17.58 - 125.12 ng/mL, 3.70 - 25.84 ng/mL, and 1.52 - 10.53, respectively. The reference values for PG I, PG II, and PG I/PG II ratio in females: < 40 years old were 22.57 - 103.90 ng/mL, 3.17 - 20.73 ng/mL, and 2.28 - 10.46, respectively; ≥ 40 years old were 14.24 - 117.81 ng/mL, 3.36 - 29.57 ng/mL, and 1.26 - 9.85, respectively.
Conclusions: The present study determined the missing reference values of serum PGs for healthy subjects of different gender and ages in Gansu Province.
