Why Conduct an Amino Acids Analysis?
The Amino Acids Test reports are useful resources for practitioners who want to gain valuable insights into the underlying causes of a variety of disorders related to Amino Acids metabolism.
The markers on the report are arranged into clinically useful groups:
- Essential/Conditionally Indispensable Amino Acids
- Nonessential Amino Acids
- Gastrointestinal Markers
- Magnesium-Dependent Markers
- B6, B12 & Folate-Dependent Markers
- Detoxification Markers
- Neurological Markers
Assessing Amino Acids in Urine vs. Plasma
Sample type used is dependent on the clinical concern.
Plasma Amino Acids - It is recommended that you fast before analysis of amino acids in plasma, as recent food intake will briefly impact amino acid levels. A fasting sample of plasma reflects a person’s pool of amino acids and is not affected by recent fluctuations in diet. Plasma amino acids are preferred for individuals with compromised kidney function.
10 business days
Before You Start
- Read the test collection instructions here.
- Sample collection must be performed by a phlebotomist, Monday - Thursday only.
2 Days Before Collection
- Hydrate.
- Avoid the following foods and supplements.
- Amino acid supplements
- Amino acid metabolite supplements (such as GABA, 5-HTP, and creatine)
- Artificial sweeteners containing aspartame (such as NutraSweet® and Equal®)
1 Day Before Collection
