ALT GPT TEST
, Introduction
test : is a blood test that checks for liver damage.
Your liver does a lot of important things for you:
❖ It makes a fluid called bile that helps your body digest
food.
❖ It removes waste products and other toxins from your
blood.
❖ It produces proteins and cholesterol.
❖ Diseases such as hepatitis and cirrhosis can damage your
liver and prevent it from doing its many jobs.
ALT is present in very high amounts in liver and kidney, and
in smaller amounts in skeletal muscle and heart. Although
serum levels of both AST and ALT become elevated
whenever diseases process affecting liver cells integrity, ALT
is the more liver-specific enzyme. A serum elevation of ALT
activity is rarely observed in conditions other than
parenchymal liver disease (cirrhosis, carcinoma, hepatitis,
obstructive jaundice or liver stroke). Moreover, its elevation
persists longer than do those of AST activity. Measurement of
both AST and ALT has some value in distinguishing hepatitis
from other parenchymal lesions.
