I think these are from a US source. We in Finland and you in UK use the same type of testing so to me those ranges you posted in the first post sound the likeliest (or close to them at least
). You
always need to compare your labs to those specific ranges that are used by
your lab, the range varies according to the testing method. Your lab's lab sheet should have the correct ranges or maybe you could ask for them at the lab office (I don't think they get them wrong there
)
