Normal ALT levels can vary slightly between laboratories but generally fall within the range of about 7 to 56 units per liter (U/L) of blood. Healthy individuals typically have low to normal ALT levels.

Elevated ALT levels can indicate various liver conditions or issues, including:

Liver Disease: Conditions such as hepatitis, fatty liver disease, and cirrhosis can lead to increased ALT levels.

Medication or Toxin Exposure: Some medications, alcohol, and exposure to certain toxins can cause ALT levels to rise.

Other Conditions: ALT levels may also be elevated due to conditions not directly related to the liver, such as muscle injury or inflammation.

The SGPT or ALT test is a routine blood test with minimal risks. The main risk is mild discomfort or bruising at the needle insertion site. Serious complications are extremely rare.

The SGPT or ALT test may also be referred to by the following alternative names:

Alanine Aminotransferase Test

Serum Glutamic Pyruvic Transaminase Test

ALT Blood Test

Liver Enzyme Test

Liver Test

The SGPT or ALT test is a valuable tool in evaluating liver health and diagnosing liver conditions. It is often included in routine blood panels to assess overall health.
