Aim: To study whether dietary intake influences liver function test.
Methods: Blood samples were obtained from patients liver diseases (n = 100) and controls (without liver diseases; n = 100) first at 07: 00 in the morning (fasting state) and then 2 h after a meal (fed state). The Hitachi-7150 automatic biochemistry analyzer was used to assess the following liver function indexes: Serum bilirubin, thymol turbidity test, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenase, gamma glutamyl transferase, SP, A and G. Statistical significance of differences between inter-group values was determined using SAS software.
Results: None of the indexes showed statistically significant differences between the fasting state and the fed state (P = 0.476-0.978).
Conclusion: Liver function test can be performed after a meal.
