1 Correlation of serum allergy (IgE) tests performed by different assay systems 
Julie Wang, MD, James H. Godbold, PhD, Hugh A. Sampson, MD  Journal of Allergy and Clinical Immunology  Volume 121, Issue 5, Pages (May 2008) DOI: /j.jaci Copyright © 2008 American Academy of Allergy, Asthma & Immunology Terms and Conditions

2 Fig 1 Linear correlation plots comparing allergen specific IgE levels obtained from Turbo-MP and Immulite with ImmunoCAP as the reference (A-F). For egg, there was 1 sample with an ImmunoCAP reading below the limit of detection and an Immulite reading of >100 kU/L. This point was deleted for the calculation of the weighted regression line; however, it was not deleted for the Bland-Altman plot of differences. DF, D farinae.

3 Fig 2 Logarithmic Bland-Altman plots comparing of allergen specific IgE levels obtained from Turbo-MP and Immulite with ImmunoCAP as the reference (A-F). Dotted lines indicate ±20%, which is accepted as the deviation for results that are similar. DF, D farinae.

4 Fig 3 Comparison of discrepant values around the decision points for the food allergens. Red indicates the patient is clinically reactive (allergic) to the specific food. Green indicates tolerance of the specific food (not allergic). Blue indicates uncertain clinical status (avoidance because of history of positive test results).
