Egg, Raw

Array 4 - Gluten-Associated Cross-Reactive Foods and Foods Sensitivity, Cyrex Laboratories

Optimal range:   0 - 0.6 ELISA Index

The presence of antibodies to Egg is an indication of food immune reactivity. Egg antigen assessed consists of egg white, egg yolk both raw. The offending food and its known cross-reactive foods should be eliminated from the diet. Egg immune reactivity is more common in children than in adults.

Since many children eventually develop immune tolerance, they may outgrow immune reactivity to Egg. Cooked egg introduced at 4 to 6 months of age may protect against egg immune reactivity. Adult onset of Egg allergy has been reported. Bird-egg syndrome, more common in adults than children, is the association between respiratory allergy to bird antigens and food allergy to eggs, and in some cases, meat from the same or different bird species.

Eggerthella lenta

VibrantAmerica (various), Vibrant America

Optimal range:   0 - 20 Relative Abundance

Eggerthella lenta is a normal human microflora that is anaerobic, non-sporulating, and Gram positive. However, an increasing number of studies have shown that it could also be an important pathogen for humans, even causing life-threatening infection under certain conditions. However, understanding its pathogenic mechanism and treatment options still need to be improved; more clinical data are needed to explore it further. The frequency of E. lenta bacteremia is increased in patients with hematologic or solid organ cancer, diabetes mellitus and also in those with appendicitis.

EIA Antigen (IgG)

Neural Zoomer Plus, Vibrant Wellness

Optimal range:   0 - 10 Relative Abundance

The CMV EIA Antigen (IgG) marker on the Neural Zoomer Plus panel measures IgG antibodies against Cytomegalovirus, a common herpesvirus that infects most people at some point in their lives.

  • EIA (Enzyme Immunoassay) is the method used to detect IgG levels.

  • The IgG class of antibodies indicates past exposure to CMV and the formation of long-term immune memory.

  • CMV is usually dormant in healthy individuals but can cause neurological issues in some cases—especially in the context of autoimmunity, immune dysfunction, or reactivation.

What Does a Moderate Elevation Mean?

  • You have been exposed to Cytomegalovirus in the past.

  • Your immune system has produced a moderately high level of IgG antibodies against CMV.

  • This may suggest either:

    • Recent past infection (especially if IgM is negative but IgG is rising), or

    • Ongoing immune system activation or reactivation, particularly relevant if symptoms are present.

Eicosadienoic 20:2 n6

Metabolimix+, Genova Diagnostics

Optimal range:   0 - 0.26 wt %

Eicosadienoic acid (EDA) is a rare, omega-6 fatty acid with a 20-carbon backbone and two double bonds (20:2n6). It is mainly formed through the downstream metabolism of omega-6s by elongating LA. EDA can be metabolized to form DGLA and AA. Literature is sparse regarding its role in the inflammatory cascade though it is known to modulate the metabolism of other PUFAs and to alter the responsiveness of macrophages to stimulate inflammation.

Eicosapentaenoic

Essential and Metabolic Fatty Acids Markers (RBCs)

Optimal range:   0.16 - 5 wt %

Eicosapentaenoic Acid (EPA) is a Polyunsaturated Omega-3 Fatty Acid and is involved in the regulation of inflammatory processes and prevention of blood clots.

Eicosapentaenoic (EPA) 20:5 n3

Metabolimix+, Genova Diagnostics

Optimal range:   0.12 - 5 wt %

Eicosapentaenoic acid (EPA) is an omega-3 fatty acid with 20 carbons and 5 double bonds (20:5n3).

EPA can either be made from the downstream metabolism of ALA or it can be obtained in the diet. Food sources include oily fish such as salmon, mackerel, cod, and sardines. In addition to diet and ALA desaturation, EPA is also available as a fish oil supplement. The desaturation of ALA to EPA is not a very efficient process, therefore dietary intake or supplementation is important.

Elaidic 18:1 n9t

Metabolimix+, Genova Diagnostics

Optimal range:   0 - 0.59 wt %

Elaidic acid (EA) is an 18-carbon chained fatty acid with one double bond in the trans formation at the 9th carbon (18:1n9t). It is the trans isomer of oleic acid. EA is the principal and most abundant trans fatty acid in the Western diet. It is found in partially hydrogenated vegetable oil and margarine. There are trace amounts of EA in the meat and dairy products from ruminant animals. EA has been shown to induce oxidative stress and alter mitochondrial signaling. It is quickly incorporated into triglycerides and cholesterol esters. Once incorporated into plasma membranes, it activates nuclear factorkB to induce adhesion molecules and become proinflammatory leading to endothelial dysfunction.

Elastase

GI360 stool profile, Doctor's Data

Optimal range:   200 - 1000 µg/mL

Elastase is a pancreatic enzyme that digests and degrades a number of proteins. A finding of low elastase in a formed stool specimen is an indicator of pancreatic exocrine insufficiency. Moderate pancreatic insufficiency is defined at 100-200 μg/mL, and severe pancreatic insufficiency as <100 μg/mL. Fecal elastase can be artefactually low due to fluid dilution effects in a loose/watery stool sample. Check the
reported consistency of the stool specimen.

Fecal elastase measured by a sensitive immunoassay is a specific marker for pancreatic function and maintains a high diagnostic accuracy among patients with small intestinal diseases. This elastase marker allows for the diagnosis or exclusion of pancreatic exocrine insufficiency and degree of severity, which can be caused by chronic pancreatitis, cystic fibrosis, pancreatic tumor, cholelithiasis or diabetes mellitus.
