Interpretive Data
Please see report for interpretive data.
Egg White (f1) - High levels of egg white IgE may predict the likelihood of sensitivity, but may not be solely predictive of reactions to cooked egg or allergy duration.
EGG COMPONENTS:
Ovalbumin (f232) - Susceptible to heat denaturation; HIGH RISK of reaction to uncooked egg; LOW RISK of reaction to cooked egg; patient likely to outgrow egg allergy
Ovomucoid (f233) - Resistant to heat denaturation; HIGH RISK of reaction to all forms of egg; patient unlikely to outgrow egg allergy with high levels of specific IgE to ovomucoid
