Arachidonic Acid

Quest Diagnostics, Quest Diagnostics

Optimal range:   5.2 - 12.9 %

Arachidonic acid (AA) is a key omega-6 fatty acid measured in the OmegaCheck test offered by Cleveland HeartLab, which assesses cardiovascular risk based on polyunsaturated fatty acid (PUFA) status.

Arachidonic Acid

OmegaCheck, Quest Diagnostics

Optimal range:   8.6 - 15.6 % by wt

Arachidonic acid is an inflammatory omega-6 fatty acid. Our bodies produce this nutrient, and its excess may lead to inflammatory diseases and mood disorders.

Arachidonic acid (AA)

VibrantAmerica (various), Vibrant America

Optimal range:   5.5 - 19.01 %

Arachidonic acid (AA) is a 20-carbon polyunsaturated n-6 fatty acid with 4 double bonds (20:4n6). Its double bonds contribute to cell membrane fluidity and predispose it to oxygenation. This can lead to several important metabolites which ensure a properly functioning immune system as well as regulate inflammation, brain activity, and other signaling cascades. AA’s metabolites are called eicosanoids which are signaling molecules.

Arachidonic Acid (AA)

Fatty Acids Profile, Essential (Serum/Plasma)

Optimal range:   0 - 250 qg/mL

Arachidonic acid is an inflammatory omega-6 fatty acid. Our bodies produce this nutrient, and its excess may lead to inflammatory diseases and mood disorders.

Arachidonic Acid/EPA Ratio

OmegaCheck, Quest Diagnostics

Optimal range:   3.7 - 40.7 Ratio

This test measures the ratio of arachidonic acid (AA) to eicosapentaenoic acid (EPA) in plasma. This ratio of the principle omega-3 and omega-6 fatty acids is a measure of the body’s eicosanoid balance. Balancing these eicosanoids in the body is an excellent way
for managing heart disease and other chronic and inflammatory processes.

Arginine

Amino Acid Analysis, Quest Diagnostics

Optimal range:   43 - 107 umol/L

Arginine is found in all protein foods and is very abundant in seeds and nuts. It is considered a semi-essential amino acid during early development, infection/inflammation, or renal and/or intestinal impairment.

Arginine

Amino Acid Profile, Qn (Urine), LabCorp

Optimal range:   5 - 69.6 umol/g Cr

Arginine is found in all protein foods and is very abundant in seeds and nuts. It is considered a semi-essential amino acid during early development, infection/inflammation, or renal and/or intestinal impairment. It has many functions in the body including:

- ammonia disposal in the urea cycle

- immune function

- stimulation of insulin release

- muscle metabolism (creatine/creatinine precursor)

- nitric oxide (NO) formation

- glutamic acid and proline formation

- glucose/glycogen conversion

- stimulation of the release of growth hormone, vasopressin, and prolactin

- wound healing

Because arginine is a precursor for nitric oxide synthesis, it is often used therapeutically in cardiovascular disease for its vasodilatory effects.

Arginine

OMX Organic Metabolomics / Diagnostic Solutions, Diagnostic Solutions Laboratory

Optimal range:   0 - 26.4 nmol/mg Creatinine

→ Arginine is a precursor of urea, nitric oxide, polyamines (putrescine, spermidine, spermine and agmatine), proline, glutamate, and creatine.

→ Levels may drop with increased need, or in renal or small intestine dysfunction.

→ Synthesis of arginine depends on citrulline levels and is less regulated by dietary arginine. Supplementation with citrulline increases plasma arginine and the production of nitric oxide (NO).

→ Arginine supplementation may lower blood pressure.

→ Metabolism of elevated arginine levels is dependent on glycine availability.

→ Plasma arginine and ornithine increased, while citrulline remained stable, following watermelon juice intake, a rich source of citrulline.
