浙江省健康人群胃蛋白酶原参考范围的建立OA

Objective To establish a reference interval for the pepsinogen(PG)Ⅰ,PGⅡ and PGⅠ/PGⅡ in healthy adult subjects in Zhejiang Province.Methods The data of 45 504 healthy adult subjects were collected,and the levels of serum PGⅠ and PG Ⅱ were detected by chemiluminescence microparticle immunoassay.The reference range of PGs were determined according to the CLSI-C28-A3 file.Results The median serum PGⅠ concentration in male was 132.62μg/L,PGⅡ concentration was 8.10μg/L,and PGⅠ/PGⅡ was 15.9.For females,they were 107.44μg/L,6.96μg/L and 15.0,respectively.PGI,PGⅡ concentration and PGⅠ/PGⅡ ratio were significantly higher in males than in females(P<0.001).The levels of PGⅠ and PGⅡ increased with age(P<0.001).Serum PGⅠ reference interval for male:59.79-234.97μg/L for 19-39 years old,63.33-294.62μg/L for 40-59 years old,64.25-333.61μg/L for≥60 years old,PGⅡ reference interval:3.33-22.60μg/L for 19-39 years of age,3.79-33.89μg/L for 40-59 years of age,4.15-42.08μg/L for≥60 years of age,PGⅠ/PGⅡ reference interval:those aged 19-39 years ranged from 7.3 to 31.4,those aged 40-59 years ranged from 5.8 to 30.9,and those aged≥60 years ranged from 3.9 to 30.7.The reference intervals of female PGⅠ were 48.79-215.68μg/L,52.10-276.01μg/L,and 64.34-317.20μg/L,respectively.The reference intervals of female PgⅡwere:2.87-23.93μg/L,3.41-33.31μg/L and 3.88-39.16μg/L,respectively.The reference intervals of of female PGⅠ/PGⅡ are 6.6-28.1,5.2-27.9 and 3.6-26.2.Conclusion This study determined the reference range of serum PGs deficiency in healthy subjects of different sex and age in Zhejiang Province.
