Is ALT SGPT 350 high, normal or dangerous? What does Alanine aminotransferase level 350 mean?

📅 Medical Review Date: April 9, 2026

Your ALT SGPT level of 350 is a High ALT SGPT level.

An ALT SGPT level of 350 U/L usually means liver cells are inflamed or damaged. It suggests liver injury. High levels of ALT SGPT can cause extreme tiredness, nausea, vomiting, right-sided abdominal pain, loss of appetite, dark urine, and jaundice. This can be caused by viral hepatitis, non-alcoholic fatty liver disease, alcohol-related liver disease, or medication side effects. Further tests are often needed to identify the cause and guide appropriate treatment.

High 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.

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.
