As Measured by Alanine Transaminase (ALT)
Alanine Transaminase (ALT) is an enzyme found primarily in the liver. ALT is released into the bloodstream when liver cells become damaged or inflamed. High levels therefore correlate to the presence of several liver conditions.
ALT’s primary function is to digest and convert food (proteins) into energy. This then allows liver cells to carry out functions such as storage of vitamins & minerals, enzyme activation and protein synthesis.
In general, ALT levels are quite low in the bloodstream.
High levels of ALT indicate signs of liver injury or disease. Excessive alcohol or drug use and prolonged exposure to medication & prescriptions can also elevate levels.
