Patient: My 2 year old son has a food allergy to soy, the first test was done against ige and his level was 1.04 ku/L (normal being 0.35) and then recently had one done against igg which that level was 13.7 H mcg/mL (Normal being 2). What is the comparison of the two? I’d like to know if there is a difference in severity or how they compare.. Something! Please and thank you!!!
