The question you have to always ask -

How many people have they seen with simular test results every year?

Push for a number.

If they cant give you a number then change the doc/institute till you get a number who can back it up with case files. If they have no clue about the numbers, then you can safely assume they dont know what outcomes are possible.

On a 35 year old house you can detect all kinds of issues every year, as testing equipment gets sophisticated and fine grained. That has nothing to do with whether the house needs repair everytime something is detected.

If they do have data, ask for outcomes. Again ask for specific numbers. No wishy washy bullshit. Keep pushing for specifics untill you have been referred to docs who have worked on similar cases.
