Abstract:

Objective To establish the reference interval of lactate dehydrogenase(LDH) among 3-14-year-old population in Hainan. Methods A total of 36 945 subjects of 3-14-year-old were enrolled from December 2020 to September 2021,and serum LDH was determined. According to age and sex,the reference interval of LDH in 3-14-year-old population was established by percentile method. The difference between established reference interval and adult LDH reference interval was compared. Results There was statistical significance for age in 3-14-year-old population(P<0.001). There was statistical significance in LDH levels between males and females of 6-14-year-old(P<0.05). LDH reference intervals of different ages and sex were established. The established LDH reference interval of 3-14-year-old population had statistical significance from that of adults(P<0.001). Conclusions The LDH reference interval of 3-14-year-old population has been established. The current LDH reference interval for adults is not applicable to 3-14-year-old population.
