Research Reports
 

In a large cohort of infants with atopic dermatitis at risk for development of food allergy, food-antigen-specific immunoglobulin E (sIgE) levels were not clinically useful for predicting food allergy development. December 2015

Allergen component-resolved diagnostic testing (CRD) is a new methodology in clinical food allergy diagnosis, improving the ability to identify specific clinical phenotypes and identifying of specific molecules causing sensitization or allergy. June 2015

How oral food challenges may be designed to assess specific characteristics of the food allergic response. August 2015

Doctors warn common food allergy tests may not identify all cases in children. July 2015

Molecular diagnostics should be used in a targeted manner for an accurate assessment and diagnosis of food allergy, which would also reduce the use of oral challenges, to predict severe reactions and allergy persistence. June 2015

Food protein allergen characterization and quantification, together with the immunoglobulin E epitope mapping, will contribute to the diagnosis/prognosis of food allergy and will lead to a better safety assessment of foods (e.g. novel transgenic foods). April 2015

To improve the accuracy of skin prick tests in diagnosing food sensitivy the quality of the food extracts needs to be improved and both IgE and IgG needs to be measured. 2015

Molecular diagnosis shows promise in allergy diagnosis. It provides information on allergenic components at the molecular level, allowing better understanding of symptoms and patient adjusted procedures. June 2014

ECG/computer combination detects allergy on average 17 minutes earlier than trained clinicians during oral food challenges. February 2015

New single blood drop diagnostic activation test (DAT) for food allergies shows promise. Research August 2011; comment December 2014

Atopy patch test in the diagnosis of food allergy in children with gastrointestinal symptoms useful for wheat sensitivity but of little value in the detection of cow's milk allergy. June 2014

Researchers in Valencia are developing a system, based on photonic biosensors, which is expected to be able to test for hundreds of different foods using a single drop of blood and delivering a result in 15 minutes. The instrument will be ready to begin clinical trials with patients from June, and testing will take place at the Hospital of the Universitaetsmedizin in Berlin. January 2013

Both skin prick and blood tests are unrelaible because they produce far too high a level of false positives/negatives. Allergen component-resolved diagnostics (CRD) tests have the potential to provide more accurate diagnoses but are not as yet sufficiently thoroughly researched. December 2012
