Appendix B: Methods

Study Population

We asked all employees to participate in order to compare sensitization and symptom 

prevalences between groups of employees with differing levels of exposure to flour dust and 

spices. We also wanted to characterize exposure in different departments.



Informed Consent and Notification

All potential study participants were given a consent form to read and sign. Each study 

participant was informed in writing of his or her own blood test results and what they meant.

Biological Samples

Approximately 15 milliliters of whole blood was collected from each participant. 

Venipuncture was performed by a physician or a trained technician following the universal 

precautions for working with blood and blood products specified by the Centers for Disease 

Control and Prevention [CDC 1998] and OSHA [29 CFR 1910.1030]. After venipuncture, 

the blood was centrifuged and the serum transported to the NIOSH laboratory for analysis. 

Specific IgE to flour dust, wheat, soybean, corn, paprika, garlic, and onion allergens was 

measured using an IMMULITE® 2000 3gAllergy™ instrument (DPC, Los Angeles, 

California). The IMMULITE 2000 is a Food and Drug Administration-cleared enzyme-

enhanced chemiluminescent enzyme immunoassay that quantifies specific IgE antibody. The 

IMMULITE 2000 has a cutoff of 0.10 killiunits per liter of serum (kU/L) IgE. The insert for 

the Immulite 3gAllergy™ Specific IgE Universal Kit describes two scoring systems, both of 

which classify specific IgE levels > 0.10 kU/L–0.34 kU/L (standard classification) and > 0.11 

kU/L–0.24 kU/L (extended classification) as very low.

The IMMULITE 2000 AlaTOP Allergy Screen (12 allergens) is a Food and Drug 

Administration-cleared qualitative chemiluminescent enzyme-labeled sequential 

immunoassay. The 12 allergens included on the matrix are Dermatophagoides pteronyssinus 

(dust mite), cat epithelium, dog dander, Cynodon dactylon (Bermuda grass), Phleum pretense 

(timothy grass), Penicillium notatum, Alternaria tenuis, Ambrosia artemisiifolia (common 

ragweed), Plantago lanceolata (English plantain), Parietaria officinalis (wall pellitory), 



Betula papyrifera (paper birch), and Cryptomeria japonica (Japanese cedar). A reactive 

result indicates that antibodies to one or more of the component allergens in the panel 

are present and the tested individual is classified as atopic. A nonreactive result indicates 

nondetectable antibodies to the component allergens.
