Has anyone had this done? My acupuncturist offers this. Saliva & urine are used for this test. The following are evaluated: Zinc taste test Saliva pH test Magnesium/potassium balance adrenal stress urine test vitamin C urine test calcium urine test oxidata urine test malabsorption urine test chemstrip urine test enzyme urine test urinary electrolytes urinary ammonia urinary nitrates urinary sugars thyroid function assessment (iodine absorption test & axillary temperature test) I can provide further information about each test if you would like. Mine indicate a diet change & some more supplements. We will discuss the thyroid (iodine absorption) at my next visit. I also want to address specifically the adrenal fatigue, since of course that indicated high. Has anyone ever done Bio-Terrain testing or something similar? Do you think the results are accurate?
