Aspartate Aminotransferase (AST) 201 U/L in Men, Women, Elderly, and Kids

Aspartate Aminotransferase (AST) levels can vary somewhat across different demographic groups, including men, women, the elderly, and children, though the significance of Aspartate Aminotransferase (AST) 201 U/L as an elevated result generally holds true across these groups. For example, men often have slightly higher 'normal' ranges for AST compared to women, partly due to differences in muscle mass. However, an Aspartate Aminotransferase (AST) level of 201 U/L would likely be considered elevated for both genders. In the elderly, AST levels can sometimes be influenced by age-related changes in organ function or the presence of multiple health conditions and medications. The body's ability to repair itself or process substances might subtly shift with age, which could impact enzyme levels. In children, especially very young children, reference ranges can differ considerably from adults, and their AST levels can be influenced by rapid growth, minor injuries, or even viral infections common in childhood.
