Is ALT SGPT 8 low, normal or dangerous? What does Alanine aminotransferase level 8 mean?

📅 Medical Review Date: December 13, 2025

Your ALT SGPT level of 8 is a Low ALT SGPT level.

An ALT SGPT level of 8 U/L usually means the liver is healthy with no inflammation. It suggests normal liver function. Low levels of ALT SGPT typically do not cause any symptoms and are not a concern. This can be caused by vitamin B6 deficiency, chronic kidney disease, or may be normal. Further tests are often needed to identify the cause and guide appropriate treatment.

Low ALT SGPT levels may indicate underlying health problems. The normal range is typically between 21 U/L and 72 U/L. If your levels are outside this range, it's important to speak with a healthcare provider. Consulting a doctor is recommended to determine the cause and appropriate next steps.

The normal ALT SGPT range for men is :21 - 72 U/L

Misdiagnosis is more common than people think—and the consequences can be serious. Delayed treatment, unnecessary medication, or worse. If you want a second opinion on your blood work, one option is to upload it to a site like wholebodyprotocol.com, where world-class doctors review your results. They charge a small fee—around $90 (though you'll want to check the latest price as it fluctuates)—and email you a detailed report. With over 12 million people affected by misdiagnosis every year, that little bit of extra peace of mind can go a long way.

Some examples of conditions that increase or decrease ALT SGPT levels include:

• Alcohol abuse
• Blockage of the bile ducts.
• Kidney damage.
• Damage to red blood cells
• Heart attack or heart failure

If you take a ALT SGPT blood test and the results are not in the normal range (21-72 U/L), your physician may recommend more tests to figure out the problem. You might also get this test if your physician thinks you have some other disease.
