The quest for solutions continues particularly with regard to early detection. This editorial comments on the utility of long-term high-normal alanine aminotransferase (ALT) in screening for MASLD. Chen et al  found that new onset MASLD can be detected by repetitively high normal ALT. Implicit in this concept is the question of what should be the accepted upper limit of normal (ULN) for ALT. It was previously set at 40 IU\/L based on studies that included people with subclinical liver disease but the new consensus is 30\/19 U\/L in healthy males\/females. Thus, when Chen et al  defines the ULN as 40 U\/L, others may view it as excessively high. It is important to recognize the variables affecting ULN e.g.  instrumentation, diurnal variations, exercise and ageing. These variables matter when the distinctions are subtle e.g.  normal vs  high-normal. In this regard, the utility of long-term high normal ALT as a disease marker could be enhanced by combining it with other biomarkers, imaging and MASLD genetics to create machine learning classifiers. All in all, Chen et al \u2019s work on long-term high normal ALT as a marker of new-onset MASLD deserves merit.<\/jats:p>","DOI":"10.3748\/wjg.v30.i42.4576","type":"journal-article","created":{"date-parts":[[2024,10,31]],"date-time":"2024-10-31T00:07:11Z","timestamp":1730333231000},"page":"4576-4582","source":"Crossref","is-referenced-by-count":9,"title":["Metabolic dysfunction-associated steatotic liver disease: The question of long-term high-normal alanine aminotransferase as a screening test"],"prefix":"10.3748","volume":"30","author":[{"given":"Terence N","family":"Moyana","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2060","published-online":{"date-parts":[[2024,11,14]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1002\/hep.20973"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jceh.2019.07.002"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v30.i10.1346"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1093\/clinchem\/21.8.1077"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.151.2.260"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-137-1-200207020-00006"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.7150\/ijms.8951"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1097\/HEP.0000000000000696"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph16050861"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhep.2020.02.020"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v30.i27.3264"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1002\/hep.22109"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v20.i42.15539"},{"key":"B14","doi-asserted-by":"publisher","DOI":"10.1002\/hep4.1479"},{"key":"B15","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhep.2020.03.011"},{"key":"B16","doi-asserted-by":"publisher","DOI":"10.1136\/gut.2009.205088"},{"key":"B17","doi-asserted-by":"publisher","DOI":"10.1097\/PAP.0000000000000312"},{"key":"B18","doi-asserted-by":"publisher","DOI":"10.1097\/MCG.0000000000000162"},{"key":"B19","doi-asserted-by":"publisher","DOI":"10.3109\/08958378.2014.955932"},{"key":"B20","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200004273421707"},{"key":"B21","doi-asserted-by":"publisher","DOI":"10.1186\/s12876-020-1165-z"},{"key":"B22","doi-asserted-by":"publisher","DOI":"10.1002\/hep.20818"},{"key":"B23","doi-asserted-by":"crossref","unstructured":"Ludwig J, Viggiano TR, McGill DB, Oh BJ.
