How can high GGT but normal ALP levels be interpreted in PBC testing?

While elevated ALP levels are typically a key marker for PBC diagnosis (usually 1.5 times higher than normal range), having normal ALP with elevated GGT presents an interesting scenario. ALP levels normally range from 44 to 147 international units per liter of blood. For a definitive PBC diagnosis, at least two of these three criteria must be met:
- ALP levels at least 1.5 times above normal
- Positive AMA test with titer of 1:40 or higher
- Liver biopsy showing PBC-related damage

With normal ALP but elevated GGT, your healthcare provider may recommend additional testing, possibly including a liver biopsy, to confirm or rule out PBC and determine the stage and progression of liver health.
