How to read a liver function test
Quick answer: To read a liver function test, look at ALT (SGPT) and AST (SGOT), check ALP and GGT, check bilirubin and check albumin.
- Look at ALT (SGPT) and AST (SGOT). These enzymes rise when liver cells are irritated. Mild rises are common and often due to fatty liver, alcohol or medicines.
- Check ALP and GGT. Together they point to the bile ducts; ALP alone can also come from bones.
- Check bilirubin. Up to about 1.2 mg/dL is typical. A mild rise of indirect bilirubin is often Gilbert's syndrome, a harmless condition.
- Check albumin. About 3.5–5.0 g/dL. Low albumin can reflect nutrition, liver or kidney problems.
Fatty liver and raised SGPT
Non-alcoholic fatty liver disease is the most common cause of a mildly raised ALT/SGPT. It's linked to extra weight around the waist, diabetes and high triglycerides, and often improves with gradual weight loss, less sugar and more activity.
When to act quickly
Very high enzymes (in the hundreds or thousands), yellow eyes or skin, dark urine or pale stools need prompt medical advice.

Frequently asked questions
Is SGPT of 60 dangerous?
It's mildly raised. That's common and often due to fatty liver, alcohol, medicines or recent hard exercise. Your doctor may repeat it or order an ultrasound.
Is SGPT the same as ALT?
Yes. SGPT and ALT are two names for the same enzyme, and SGOT is AST.
Why is my lab's normal range different?
Each lab sets ranges for its own machines and methods, so they vary a little. When your report prints a range, the checker shows it and uses it for most tests. For tests with standard medical cut-offs, such as HbA1c, cholesterol and vitamin D, it uses those cut-offs.
