Liver function tests (LFTs)
measure liver injury, rather than liver function. They are a group of blood tests
that measure substances in the blood that reflect whether the liver has been injured
and the extent of the injuries. Sometimes these tests are also called a liver panel.
The tests usually include the following: alanine transaminase (ALT), aspartate transaminase
(AST), alkaline phosphatase (ALP), albumin, total protein, and total and direct
The liver is a complex organ, located in the upper right corner of the abdomen,
which has many vital roles. The liver stores fuel for the body that has been produced
from sugars, and it is involved in the processing of fats and proteins. Bile produced
by the liver is involved in the digestion and absorption of fat in the intestines.
The liver also makes proteins that are essential for blood clotting, and it helps
remove poisons and toxins from the body
Alanine Transaminase (ALT)
Alanine transaminase is an enzyme that is important in the processing of proteins.
This enzyme is found in large amounts in the liver, and small amounts of this enzyme
are also found in the heart, muscle, and kidney. When the liver is injured or inflamed,
the levels of ALT in blood usually rise; therefore, this test is done to check for
signs of liver disease. The ALT is elevated, for example, in some viral infections
of childhood that may affect the liver, such as mononucleosis.

Why Should I get my liver tested?
Many substances American's use on a daily basis can have harmful effects
on the liver. Alcohol and Tylenol© (acetaminophen) are both heavily used and while
it is well known alcohol can be harmful, however Tylenol, which is generally regarded
as safe, can be harmful if large doses are used for any length of time. Another
large group that would be excellent candidates for an ALT test would be those who
use the popular class of cholesterol referred to as "statins". They include Lipitor
(atorvastatin), Zocor (simvastatin), Pravachol (pravastatin), Mevacor (lovastatin),
and Lescol (fluvastatin). These drugs for a certain percentage of the population
can cause harmful, yet reversible, liver complications. The ALT test can help screen
for problems from use of these substances or other complications such as hepatitis.
