Alanine Aminotransferase (ALT)

What is Alanine Aminotransferase (ALT)?

Alanine aminotransferase (ALT) is a cytoplasmic enzyme found primarily in the liver. Due to its high concentration in liver cells, ALT is considered a highly specific marker for liver cell injury and liver-related conditions.

ALT as a Diagnostic Tool for Liver Conditions

ALT plays a crucial role in diagnosing and monitoring hepatocellular diseases, particularly in the early stages of viral hepatitis. Elevated ALT levels often indicate liver inflammation or damage, making it an essential enzyme in liver function tests.

Conditions Associated with Elevated ALT Levels

While ALT is most commonly associated with liver diseases, significant elevations can also be observed in cases of acute cholestatic conditions such as choledocholithiasis (bile duct obstruction). Additionally, ALT levels may rise markedly during episodes of acute cardiac failure or profound hypotension, reflecting systemic effects on liver perfusion.

Liver Function Testing in Slough and Nearby Areas

Individuals in Slough and surrounding areas including Burnham, Windsor, Langley, and Maidenhead can access private liver health screening and ALT testing. Early detection of liver abnormalities through alanine aminotransferase (ALT) blood tests can help diagnose conditions such as hepatitis, fatty liver, and biliary obstruction, supporting proactive healthcare and liver disease prevention.
