Food Allergy Profile (IgE) is a blood test that measures levels of IgE antibodies to specific foods, which can help diagnose food allergies.

​
iollo markers that associate with Food Allergy Profile (IgE)*

​
Arachidonic acid

Arachidonic acid is an omega-6 fatty acid that can be converted to pro-inflammatory eicosanoids. Elevated arachidonic acid levels may promote allergic inflammation and increase IgE levels in some individuals.

​
Docosahexaenoic acid

Docosahexaenoic acid (DHA) is an omega-3 fatty acid with anti-inflammatory properties. Higher DHA levels may help reduce allergic inflammation and IgE production in some people.

​
Eicosapentaenoic acid

Like DHA, eicosapentaenoic acid (EPA) is an anti-inflammatory omega-3 fatty acid. Adequate EPA levels may have a protective effect against allergies and elevated IgE.
