IgE Antibody Levels Double in Last 35 years

Not surprising....IgE antibody levels have doubled in patients over 50 years of age since the 1970s, and the rate of decline in IgE as we age is becoming slower than previous, this according to a NHANES study released at the recent ACAAI meeting in Phoenix. This is probably a result of the 'allergy epidemic,' although changes in assaying IgE may also account for some of the change.
