Background: The enhanced liver fibrosis (ELF) value is a non-invasive serum marker used for assessing liver fibrosis in chronic liver disease. To use the ELF value for the purpose of screening the general population and selecting subpopulations at high risk, it is important to know the normal range of ELF values as a prerequisite. Aims: We aimed to define the normal range of ELF values by recruiting apparently healthy subjects and investigating factors influencing ELF values in subjects with minimal fibrotic burden. Methods: ELF values were determined in a cohort of healthy subjects who underwent a health check-up and in healthy living liver donors who were screened for transplantation. None of subjects suffered from chronic heart disease, diabetes mellitus, metabolic syndrome, hepatitis B, hepatitis C, or human immunodeficiency virus infection, systemic autoimmune disease or liver dysfunction. Results: Among 183 subjects analyzed, the normal ELF 5th through 95th percentile range was 5.95-8.73. Body mass index (P = 0.014) and male gender (P = 0.015) showed significant positive correlations with ELF value, whereas age did not. In multivariate linear regression analysis, platelet count was identified as the only independent factor influencing the ELF value (β=-0.006, P = 0.016). When considering the difference in ELF values between genders, the normal range of men was defined to be 6.72-8.93, this was slightly higher than that of women, 5.69-8.67. Conclusions: We identified the normal range of ELF values and found that it can be significantly influenced by platelet count even in the healthy population.
