Liver function tests
Normal blood test results for typical liver function tests include:
- ALT. 7 to 55 units per liter (U/L)
- AST. 8 to 48 U/L
- ALP. 40 to 129 U/L
- Albumin. 3.5 to 5.0 grams per deciliter (g/dL)
- Total protein. 6.3 to 7.9 g/dL
- Bilirubin. 0.1 to 1.2 milligrams per deciliter (mg/dL)
- GGT. 8 to 61 U/L
- LD. 122 to 222 U/L
- PT. 9.4 to 12.5 seconds
These results are typical for adult men. Normal results vary from laboratory to laboratory and might be slightly different for women and children.
Your doctor will use these results to help diagnose your condition or determine treatment you might need. If you already have liver disease, liver function tests can help determine how your disease is progressing and if you're responding to treatment.
