Immunoglobulin E (IgE)
What This Test Measures
Allergy antibody; parasitic defense
Conventional vs. Functional Optimal Range
The gap between these ranges is why you feel terrible with "normal" labs. Conventional medicine waits for disease. Functional medicine optimizes for health.
Gabriel's Take
IgE mediates allergic reactions. Elevated IgE (>100) = allergies, asthma, eczema, or parasites. Functional optimal <50 IU/mL. High IgE flags atopy and histamine issues. Gabriel checks IgE in allergy and histamine intolerance cases.
When This Test Is High
Allergies, atopy, parasitic infections
When This Test Is Low
Usually not significant
Related Conditions
