New Methodologies

  • Alternaria Assay — The purpose of the study was to provide objective data for deciding which assay to use for the measurement of Alternaria in the National Health and Nutrition Examination Survey 2005-2006. In collaboration with Dr. Charles S. Barnes at Children’s Mercy Hospital, NIEHS investigators compared the performance characteristics of four different assays for Alternaria allergen in house dust.
  • Dust Sampling — The objectives of this study were to compare allergen concentrations between subject- and technician-collected samples and to examine the sample return rate. NIEHS researchers concluded that with some limitations, subject-collected dust sampling appears to be a valid and practical option for epidemiological and clinical studies that report allergen concentration as a measure of exposure.
  • ELISA Assay Proficiency — In collaboration with other labs around the country, NIEHS scientists completed a study that examined issues related to quality control in the laboratory measurements of allergens.
  • Multiplex Assay — Through the Small Business Innovation Research (SBIR) program at NIEHS, the team initiated a research project for the development of a laboratory assay that would allow for the simultaneous analysis of multiple samples for multiple indoor allergens.
