First of all, that attitude? Absolutely the right one. "PBC does not have me" — that's the energy! 🙏 Now let's break this down clearly, because there's actually a lot to unpack here.

Does a positive AMA titer and AMA-M2 automatically mean PBC?

Not automatically, no. A positive AMA (at 1:40 or higher) is a *strong* Show Full Answer

First of all, that attitude? Absolutely the right one. "PBC does not have me" — that's the energy! 🙏 Now let's break this down clearly, because there's actually a lot to unpack here.

Does a positive AMA titer and AMA-M2 automatically mean PBC?

Not automatically, no. A positive AMA (at 1:40 or higher) is a *strong* indicator of PBC, but to be formally diagnosed, at least two of these three criteria must be met:

- ALP elevated at least 1.5x the upper limit of normal
- AMA titer of 1:40 or higher
- Liver biopsy showing PBC-related damage

Since your liver enzymes — including ALP — are completely normal, you currently only meet *one* of those criteria. That's why your GI is in "watch and wait" mode, which is actually a recognized and reasonable approach in this situation. Is "watch and wait" normal protocol?

Yes, it can be. If someone is AMA-positive but has no symptoms and normal liver enzymes, many doctors recommend ongoing monitoring rather than immediately starting medication. Routine blood tests every 6 to 12 months to track liver function and antibody levels is a common approach.

The experience shared about the other person being monitored for 6 years without medication isn't unheard of — some people remain stable for a long time without biochemical evidence of progression. Is treatment dependent on the individual?

Absolutely yes. The standard of care for PBC is very much patient-specific. Without elevated liver enzymes or confirmed liver damage, starting medication may not yet be warranted. Your upcoming Fibroscan will also provide helpful information about liver stiffness and any early fibrosis, which could further guide your doctor's decisions. A few important things to keep in mind while monitoring:

- Keep all follow-up appointments consistently
- Avoid alcohol and any medications that could stress the liver
- Let your doctor know right away if you develop new symptoms like unusual fatigue or itching
- Make sure your liver panels are being checked regularly — every 6 to 12 months at minimum

Seeing a hepatologist (liver specialist), if you haven't already, could also be really valuable given the complexity of your situation. They tend to have deeper familiarity with cases like yours. The confusion is completely understandable — this is genuinely complex territory. But the fact that your liver enzymes are normal right now is actually a *good* thing. Staying informed, keeping up with monitoring, and working closely with your care team are the best tools available right now. You're already doing all the right things. 💪
