60-80? That seems high - I don't think you could be at that without taking a lot of supplements every day.
I think 30 is the lab normal (and it was recently raised to 30 from 20) - though a lot of people are below that when tested.

It might be. But it could also be more.
Doesn’t mean that isn’t true, but I’d need more to be persuaded.
