ALT SGPT 348

Your ALT SGPT level of 348 is a High ALT SGPT level.

An ALT SGPT level of 348 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.
