Enzyme immunoassays for total and allergen specific IgE in population studies.

Allergen-specific IgE to inhalant and food allergens and total IgE values in China: comparison of 2 commercial immunoassays.

The Age Impact on Serum Total and Allergen-Specific IgE

Aging is accompanied by a progressive decline in almost all functions of the immune system. To investigate a possible impact of age on IgE production, this study evaluated total and allergen-specific serum IgE levels in a large cohort of allergic patients. This study included 6,370 allergic patients (2,961 females, 3,409 males; mean age, 21.7 years; age range, 0-96 years). Total and allergen-sp...

The predictive value of total serum IgE for a positive allergen specific IgE result.

BACKGROUND Measurement of total serum IgE and allergen specific IgE is often requested to assess possible allergy. As public awareness increases, so do requests for allergy assessment; unless there is a clear "allergen suspect" in the history, several allergen specific IgE requests may be made. This increases the likelihood of detecting borderline increases in allergen specific IgE of uncertain...

[Usefulness of total IgE in predicting positive allergen specific IgE Tests in Korean subjects].

BACKGROUND Total IgE levels in allergic patients tend to be higher than those in healthy individuals. We evaluated the usefulness of total IgE levels in predicting positive results of allergen specific IgEs in multiple allergen simultaneous tests. METHODS A total of 133 patients with allergic symptoms were evaluated. Allergen specific IgEs were detected using 3 different kits: Allergy screen ...

Evaluation of serum s-IgE/total IgE ratio in predicting clinical response to allergen-specific immunotherapy.

BACKGROUND To date, no predictive tests for the clinical response to allergen-specific immunotherapy (ASI) are available. Therefore an in vivo or in vitro test would be of great value. OBJECTIVE We sought to evaluate pretreatment parameters used in diagnosing allergic rhinitis and determining serum specific IgE (s-IgE) levels, serum total IgE (t-IgE) levels, and blood eosinophil counts and to...
