I understand that you support continuing supplements before functional testing, and I do the same with my patients. However, I’m curious about your thoughts on B6 supplementation before testing. Some of my patients are on a methylated multivitamin containing 75 mg of Vitamin B6 (as pyridoxine HCl and pyridoxal 5'-phosphate), and their fasting B6 levels often come back significantly elevated—sometimes double the upper limit. This causes concern for them. What are your thoughts on this?
In general I don't think elevated B6 is useful as a marker of neuropathy. The presence of neuropathy is useful as a marker of neuropathy. If they stop the supplement for a week and the level is normal, what insight did you gain?
From CheatSheet 3: 'Free copper index: subtract (ceruloplasmin * 3.15 in mcg/L) from serum copper in mcg/L. This is the free copper. Divide this by the serum copper to yield the % free copper. If free copper is above 15 or the % free copper is above 15%, see Elevated Free Copper below.'
My ceruloplasmin is 19.3 mg/dL and serum copper is 13.2 µmol/L;
Conversion: ceruloplasmin 193,000 µg/L; serum copper 838.8072 µg/L; I used unitslab.com for conversion of copper.
If someone wants to get their nutrients tested but is on a feeding tube for part of their nutrition, would the vitamins added to the formula impact lab test results?
Hi Chris, Multiple times in your cheat sheet you recommend the Genova ION + 40 Amino Acids test (test #3102). Going to the provided link at https://www.gdx.net/nutrition, I don't see that test anywhere!
Has it been discontinued? If so, what test(s) do you recommend instead? I was about to order one.
Chris, I believe you used to live in New York & are likely familiar with the legal limitations around Genova testing in this state. Do you have any recommendations for how a New Yorker could get a blood draw for the NutrEval, i.e. via a physician in New Jersey or Connecticut, potentially?

Hi Chris,

My ceruloplasmin is 19.3 mg/dL and serum copper is 13.2 µmol/L;
Conversion: ceruloplasmin 193,000 µg/L; serum copper 838.8072 µg/L; I used unitslab.com for conversion of copper.
Calc: 19.3 µg/L x 3.15 = 607950 µg/L;
838.8072 µg/L - 607950 µg/L= -607,111.1928 µg/L -> free copper
-607,111.1928 µg/L : 838.8072 µg/L = ~ -723,78 %
This makes no sense - but I can't find the mistake
free copper as calculated by the lab is 2.87 µmol/L

Some of them, but not in a way that makes testing not useful.

thanks.
Doctors can order it inside their portal and DTC companies like truehealthlabs should allow you to order it. If all else fails get the NutrEval.
