Hello all, I just recieved my nutrEval(plasma) and metametrix 2100 stool analysis test results and have been trying to piece all of it together. My pcp does not know anything about these results and I am currently looking for an intergrative medicine doctor who can help me interpret these results. So far here is what I have made of some of the markers in my nutrEval results with the help of caledonia/richs guide(thanks for putting it all together) and genovas guide www.gdx.net/core/interpretive-guides/Amino-Acids-Interp-Guide.pdf: suspect impaired hepatic detoxification due to: High Cysteine Very high cystathionine Low Taurine (all suggestive of impaired methylation,sulfation, amino acid congugation) Very high beta alanine (known to lead to taurine deficiency, hence my low taurine) The High Cystathionine, alpha-aminodipic acid, beta alanine, betaaminoisobutyric acid and Low cysteine (compared with cystathionine) or low taurine (compared to cyst(e)ine) would indicate an increased need for vitamin B6 (Mg, riboflavin, zinc needed for b6 activation) The high sarcosine, high homocysteine(tested in past), 1-methylhistidine, 3-methyhistidine, cystathionine indicates a increased need for folic acid (THF) and a partial methylation cycle block. Also the high FIGlu would also suggest depleted folates. No detection of succinic acid, which i read is a common finding in people with cfs. I don't understand why genova has recommended more b12 for me, I was and still taking 5000mcg/day for a long time and methylmalonic acid marker is fine.
