Isolated, persistent elevations of aspartate aminotransferase (AST) without plausible explanation may lead to diagnostic confusion. Macro-enzyme aspartate aminotransferase (macro-AST) is an uncommon and benign cause of persistently elevated AST levels in the absence of other diseases. We present a case of macro-AST in an otherwise healthy adult male which was confirmed by polyethylene glycol (PEG) precipitation.
孤立性、持续性天冬氨酸氨基转移酶（AST）升高且无合理原因可解释，可能会导致诊断困惑。巨酶天冬氨酸氨基转移酶（巨AST）是在无其他疾病情况下导致AST水平持续升高的一种罕见且良性的病因。我们报告一例在其他方面健康的成年男性中的巨AST病例，该病例经聚乙二醇（PEG）沉淀法得以确诊。
