Many people have hidden amino acid impairments that go undiagnosed. Rather than just being associated with specific symptoms, they may often be related to or increase susceptibility to chronic or degenerative disease. Amino Acid (AA) Analysis provides a wealth of valuable information. Therefore it is recommended any time a thorough nutritional and metabolic workup is called for.

Amino Acid Analysis
aids in identifying a variety of conditions

Cardiovascular disease
Dietary protein inadequacy
Forms of protein intolerance
Gastrointestinal dysfunctions

Impaired immune function
Oxidative stress
Reduced overall detoxification capacity
Renal and hepatic dysfunction
Vitamin and mineral deficiencies

Plasma versus Urine Amino Acid Assessment

Doctor's Data offers both plasma and urine amino acid analysis. It is important to understand the differences. Plasma amino acid analysis
shows what is being transported at a single moment in time. Overnight fast & pre-prandial collection reduces dietary influence and accents metabolic status. Plasma analysis is recommended if there is known abnormal renal function. Urine amino acid analysis shows metabolic status over a 24 hour period. Patterns are more distinctive in urine in relation to enzyme functions, cofactor adequacy, and metabolite transport. Renal function must be normal, and the sample must be a first morning void for accurate results.
    Plasma AA Assessments for:

Status of essential AA supply
Status of conditionally essential AA supply
Markers of neurologic dysfunction
Markers of vitamin and mineral deficiency
Markers of renal function
          Urine AA Assessments for:

Markers of vitamin and mineral deficiency
Markers of bone loss or muscle wasting
Markers of intestinal dysbiosis
Markers of renal function


Customized solution for your patients

Your patient's specific test results will be used to customize an amino-acid formula designed to target their deficiencies and goals (see image). These customized formulations provide appropriate amounts of essential and conditionally essential amino acids delivered in a balanced ratio.

This recommended Amino Acid Supplement Schedule is calculated based upon the difference between the test results for the specific patient and optimal urine levels, and guidelines for human amino acid requirements as provided by the Food and Nutrition Board of the NRC. The calculated levels of amino acids only apply to ORAL administration.
