HER2 report unclear - input?

I picked up my post-surgical path report today and the Her2 results from Mayo were there. The doctor had warned me that they were confusing and would require further conversation with the oncologist, and he was right. Basically it says that the ratio is 2.5 and that falls within their positive range, but that in their opinion "this result may not reflect true HER2 amplification." (it was FISH by the way)

So how helpful is that? The ratio is positive but the doctor doesn't think so? 

Any thoughts, other than the second opinion I see coming...
