Optimal range:   1.1 - 1.9 wt %

Lignoceric acid has 24 carbons and no double bonds (24:0). It can be formed from behenic acid using the elongase enzyme. It is found in peanuts, nut and seed oils. It can also be found in wood tar. Lignoceric acid is one of many fatty acids which compose brain tissue and myelin.

1019 IgG Food Antibodies - Bloodspot, Genova Diagnostics

Reference range:   None Detected, Very Low, Low, Moderate, High

The Lima Bean marker measures IgG antibodies to proteins found in lima beans. Results are reported as none detected, very low, low, moderate, or high. These levels reflect immune exposure and recognition rather than a true legume allergy. Interpretation should consider digestive symptoms, portion size, preparation method, and overall gut health.

Limosilactobacillus reuteri is a lactic acid bacterium that naturally resides in the gastrointestinal tract of humans and other animals. It is considered a probiotic due to its potential health benefits, particularly in gastrointestinal health. In the context of a GI test, the presence of Limosilactobacillus reuteri can indicate its role in maintaining gut health and its potential therapeutic effects.

Essential and Metabolic Fatty Acids Markers (RBCs)

Optimal range:   10.5 - 16.9 wt %

Linoleic acid is by far the most abundant polyunsaturated fatty acid in most human tissues. Linoleic acid is an essential fatty acid, and low levels indicate dietary insufficiency.

3200 Metabolomix+ - FMV Urine, Genova Diagnostics

Optimal range:   18.8 - 28.3 wt %

Linoleic acid (LA) is the only essential omega-6 fatty acid and must be obtained from the diet.

From LA, other omega-6s can be created using elongase and desaturase enzymes. LA contains 18 carbons, with 2 double bonds, the first of which is at the 6th carbon position (18:2n6).

LA is found in nuts and vegetable oils (corn, soybean, canola, sunflower, etc.) as well as most meats. When the double bonds of LA are arranged differently, the term conjugated LA (CLA) is used. Although technically CLA can be termed a trans-fat, a natural type of CLA can be obtained in the dietary intake of meat and milk from ruminant animals. There are many isomers of CLA – some beneficial and others are not as well defined. There is some controversy regarding how much LA is needed from the diet for adequacy. Although LA is needed to synthesize downstream fatty acids, it may lead to increased inflammatory fatty acid production.

Essential and Metabolic Fatty Acids Markers (RBCs)

Optimal range:   6 - 12.3 Ratio

LA/DGLA is a fatty acid ratio.

LA/DGLA stands for linolenic acid (=LA) and dihomogammalinolenic acid (=DGLA).

The LA/DGLA ratio is a biomarker that can indicate functional zinc deficiency.
