Alanine aminotransferase or ALT is an enzyme located primarily in the liver and kidneys. The level of ALT in the blood is usually low, however, a rise in serum levels is indicative of liver damage. A high level of ALT can usually be detected before obvious signs of liver injury occur, such as jaundice.
An ALT blood test is used to screen for liver disease or injury. It measures the amount of ALT in the blood. Increased serum levels of ALT may also confirm muscle damage if there is an absence of symptoms which may indicate liver damage. ALT along with aspartate aminotransferase (AST) are the most commonly used biomarkers in the clinical diagnosis of liver damage.
ALT levels increase when the liver is damaged potentially because of alcohol abuse, medication use, cirrhosis, muscle injury, kidney damage, liver infection as well as trauma. Therefore, if you are concerned about the health of your liver you may choose an ALT blood test. Equally, if you have recently experienced muscle damage your ALT levels may be raised.
