This test requires a blood draw, so please ensure you can refer to a phlebotomist in the clients area before you order this test. If you cannot find one, please consider the Metabolomix instead.
The NutrEval, and its subpanels, have been redesigned and reimagined to offer even greater clinical utility! Our nutritional profiles help practitioners identify root causes of dysfunction and treat clinical imbalances that are inhibiting optimal health. These advanced diagnostic tools provide a systems-based approach for clinicians to help their patients overcome chronic conditions and live a healthier life.
NutrEval Plasma is a nutritional analysis that allows assessment of nutritional inadequacies or imbalances that may be playing a causative role in complex chronic conditions.
The NutrEval Plasma report provides for easy interpretation and enhanced clinical utility and includes a Suggested Supplement Schedule that offers personalized recommendations based on test results. The report also includes an Interpretation-At-A-Glance page which depicts facts on nutrient function, causes and complications of their deficiencies, and dietary sources.
The complete NutrEval Plasma with Vitamin D offers:
- Metabolic Analysis (urine organic acids)
- Plasma Amino Acid Analysis (essential and non-essential amino acids, plus intermediary metabolites)
- Essential and Metabolic Fatty Acids (red blood cell essential and non-essential fatty acids, including Omega-3 and Omega-6 fatty acids)
- Oxidative Stress Analysis (blood and urine biomarkers indicative of oxidative stress)
- Elemental Markers (both nutrient and toxic elements)
- Vitamin D status
Overview
What is the difference between plasma and urine amino acids?
Certain amino acids are measurable in blood versus urine and sample type selection depends on the clinical concern. The key differences between plasma and urine amino acids are summarized below.
| Plasma Amino Acids (Fasting) | Urine Amino Acids (First Morning Void) |
| Fasting sample represents "steady state" pool of amino acids; not affected by short-term diet fluctuations | Represents recent dietary intake and metabolism - more variable compared to plasma |
| 36 analytes | 40 analytes |
| Useful for mood disorders, or uncontrolled diets | Useful for controlled diets, to assess protein maldigestion, oxidative stress, vitamin/mineral cofactors affecting amino acid metabolism |
| Amino acid levels influenced by abnormal kidney function; preferred if patient has proteinuria | Amino acid levels influenced by abnormal kidney function; urine testing dependent on healthy kidney function (biomarkers ratioed to urine creatinine) |
| Requires a blood draw | Requires a urine sample |
