Same as Pam Killeen. She is incredibly qualified.
Plus, all the new people have to work with Dr Wilson for a long time. The newbies do not interpret by themselves. There is a report from the lab, and Dr Wilson looks at it as well.
Dav1e... There is indeed such a thing as hidden copper. As well as hidden aluminum, lead, mercury, etc. I had them all hidden.
When you is very weak, the 1st hair analysis often shows ZERO toxins. That is because when your body is weak and your ability to clear toxins is limited, it does not even make an attempt to remove them.
I showed almost no aluminum for a long time. There was a slight trend up, then all of a sudden aluminum spiked up 6 months ago.
This was after 2.5 years. Your body removes what it can ...when it can... with the energy you have available.
All of the toxins are increasing in my hair as I get better at eliminating them.
A important part is getting your bilary system working. Even Dr Watts from TEI has an article on copper and mentions that if you bile is not flowing well, copper will accumulate.
Ann-Louise Giddleman talks about hidden copper in her book. She has also observed it many time where it is low at the beginning, but then spikes later. She uses TEI by the way. I worked with her for about 9 months.
But, ARL does tend to put more emphasis on hidden copper and other toxins. I have heard that Dr Eck had a lot of copper, so it is natural that his program puts more emphasis on it.
It is complicated, and not clear cut.
The user, "onedaysoon" is one that I know of that was told she had hidden copper, didn't believe it, and then switched to TEI and did much better. So in some case, it seems they may over-play it.
Others had the opposite happen, they were improving with ARL, switched to TEI and got much worse. We are all a little different.
ARL might not work directly with you in Europe, but I know Pam has European clients.
Good luck whatever you try.
