An AMA titer of 1:98 is considered significant. For a PBC diagnosis, a titer of 1:40 or higher is one of the key thresholds doctors look for. So a result of 1:98 is well above that mark and is considered a strong indicator.

That said, a PBC diagnosis requires meeting at least two of these three criteria:

- ALP levels at least 1.5 times the upper limit of normal
- AMA titer of 1:40 or higher
- A liver biopsy showing bile duct damage consistent with PBC One important thing to know: a higher AMA level does NOT mean the disease is more severe. Studies show that AMA levels don't predict how serious PBC is, how long symptoms last, or how elevated liver enzymes will be. So try not to read too much into the number itself.

Your doctor will look at the full picture — AMA titer, ALP levels, symptoms, and possibly imaging — to confirm a diagnosis and guide next steps.
