SGPT ALT refers to a blood test that measures the level of the enzyme Alanine Aminotransferase (ALT). Formerly called SGPT, ALT is primarily found in liver cells, and elevated levels in the blood often indicate liver damage.
Understanding ALT (SGPT)
- What it is: Alanine Aminotransferase (ALT), previously known as Serum Glutamic Pyruvic Transaminase (SGPT), is an enzyme mainly located in the liver.
- Purpose of the test: The ALT test measures the amount of this enzyme in the blood.
- Clinical significance: When liver cells are damaged, ALT is released into the bloodstream, causing levels to rise. Therefore, a high ALT level is a strong indicator of liver injury or disease.
Why is the ALT (SGPT) Test Important?
The ALT test is a crucial tool for assessing liver health. It can help:
- Detect liver damage early.
- Monitor the progression of liver diseases.
- Evaluate the effectiveness of liver treatments.
What do Elevated ALT Levels Mean?
High ALT levels can be caused by various factors, including:
- Liver diseases: Hepatitis (viral, alcoholic, or autoimmune), cirrhosis, and liver cancer.
- Medications: Certain drugs can cause liver damage.
- Other conditions: Obesity, diabetes, and muscle injuries can also elevate ALT levels.
