Then it looks like copper and ceruloplasmin can be done only for piece of mind but cant be used really as a tool accessing ones copper status correctly. It might show recent activity but it doesnt mean too much for long term status. At least we might use them short term, since both can go enough up and down within days, so to show if the metabolism is moving and at what direction.
Sometimes you see ceruloplasmin of 17-18 that dont tend to move up much no matter the stimulus was given.
It seems difficult to say if one is copper toxic or deficient even with hair test checked plus serum copper and cerulo.
Have seen mine hair copper with level in the low acceptable range with free serum copper of 26.5 (27.7%) (sCu 95.5)(Cp 23). Hair copper at same time wasnt sky high, but low end (1.1 TEI).
How we can imagine what the true status is when hair copper looks on the lower end of norm (1.1 TEI) with little elevated free copper from blood and it shows overactive thyroid and adrenals (fast oxidation), when compared this to
a hair test with same hair copper of 1.1 TEI and it shows just the opposite slow thyroid and adrenals (slow oxidation).
That means we can have low end of norm hair copper in fast oxidation and same level of hair copper in slow oxidation, but we can not distinguish clearly if one is copper toxic or copper deficient, unless for ex. one presents very high above range hair copper and appears in slow oxidation.
It seems only a copper (feed in) provoking test should be able to show what ones true copper status is.
Why , copper and ceruloplasmin can show you free copper. And it is a good indicator of what is going on.
But you have to do these tests at the same time. You cant do ceruloplasmin today and copper tomorrow, or at different times. or different labs. This is what I said to Herrfish.
His free copper is 10%. It is not low. But I imagine those numbers are not correct, since those tests are taken not in the same day. it is like taking insulin and sugar on different days. It doesnt work like that.
Hair does not show your copper levels. status. Hair shows copper only when metalothionein fails.
In serum no one looks at copper levels, since copper can go up and down, based on metabolism. they look at free copper . And I think free copper is a good indicator of what is going on.
Free copper can be high with copper 40 in serum. and low with copper 160 serum. the actual level of copper does not tell you anything.
High free copper can be in 4 lows. it does not matter fast or s low oxidation that is
TE and ARL sometime call oxidation fast or slow in 4 high s or 4 lows. I think it is wrong. I am talking only about classical slow and fast. Not burned out fast or stressed out slow. or fake fast with higher phosphorus.
Also I look at phosphorus, also, sometimes phosphorus can tell the toxic and fake fast oxidation.
But you are right, it is verry hard to tell just by looking at one source of mineral information. this is why I always checked many things for people that I helped before. I found the best way to do it, 1) hairtest 2) amino acids blood 3) amino acids urine 4) minerals blood 5) minerals urine. and ABG or VBG. Personally I do this for myself. From this your can see your metabolism like an open book.
I see that you are looking at the system and want to systemize everything. This is what I did when I was looking for the system just like you.
