The full form of ALT is alanine transaminase.
Understanding ALT
ALT, or alanine transaminase, is primarily an enzyme found in the liver. This enzyme plays a vital role in the body's metabolism. Specifically, it helps convert alanine, an amino acid, into pyruvate, a key component in energy production. The level of ALT in the blood is often measured to assess the health of the liver.
Why is ALT Measured?
An ALT test, which is a common blood test, quantifies the amount of ALT present in your blood. Usually, only a small quantity of ALT is circulating in the bloodstream. However, when liver cells become damaged or injured, they release increased amounts of ALT into the blood. Therefore, elevated ALT levels can indicate potential liver damage or disease.
What can elevated ALT levels mean?
- Liver disease, such as hepatitis
- Fatty liver disease
- Liver injury due to medications or toxins
- Other liver conditions
It is important to consult a healthcare professional for a proper diagnosis if you have high ALT levels.
