Determination of the upper limits of normal serum alanine aminotransferase (ALT) level in healthy Turkish population

Upper Limits of Normal for Serum Alanine Aminotransferase Levels in Chinese Han Population

BACKGROUND AND OBJECTIVES Serum alanine aminotransferase (ALT) activity is the most common tool for the assessment of liver diseases. However, it is not clear whether the current normal ALT range really discriminate patients with or without liver diseases. The present study was to establish a new normal range of ALT and examine its ability to identify patients with hepatitis B or nonalcoholic f...

normal limit for serum alanine aminotransferase level and distribution of metabolic factors in old population of kalaleh, iran

backgrounds normal or elevated values of serum alanine aminotransferase level (alt) vary in different studies mostly related to characteristics of reference population including age, gender, body mass index, nonalcoholic fatty liver disease (nafld), and metabolic syndrome prevalence. objectives to measure upper normal limit (unl) for serum alt in an apparently healthy iranian old population (wh...

Upper limit of normal for alanine aminotransferase: quo vadis?

Several studies suggest that a substantial number of patients with normal serum alanine aminotransferase (ALT) levels, defined by current thresholds, have ongoing hepatic necro-inflammation and fibrosis, and are at risk of liver disease progression. A major problem lies in the definition of normality. The current upper limit of normal (ULN) for ALT was established in the 1980s when reference po...

Re-evaluation of serum alanine aminotransferase upper normal limit and its modulating factors in a large-scale population study.

BACKGROUND The upper normal limit (ULN) of serum alanine-aminotrasferase (ALT) normal range was recently challenged, because patients diagnosed with liver diseases may have 'normal' or near-'normal' ALT levels, and because possible modulators are often ignored in determining normal range. AIM To estimate the ULN for serum ALT and to identify factors modulating it. SUBJECTS AND METHODS We re...
