What does low level of ALT on a blood test mean?

A low level of alanine aminotransferase (ALT) on a blood test is typically not a cause for concern. ALT is an enzyme primarily found in the liver, and low levels generally indicate healthy liver function. However, very low ALT levels can sometimes be associated with certain conditions, such as vitamin B6 deficiency or other metabolic disorders. Always consult a healthcare professional for personalized interpretation and guidance based on individual health contexts.
