Peanut AllergyIMMULITE 2000NCT01950533
The Utility of Food-Specific IgE Measured With the IMMULITE 2000 Assay to Predict Symptomatic Food Allergy
An observational study of Peanut Allergy and Milk Allergy, run by National Jewish Health at 1 site in United States.
Trial summary
Food allergy is on the rise within the pediatric population. Having food allergy can cause medical, nutritional and psychological issues in those who suffer with it. Although making the appropriate diagnosis of food allergy is very important, properly diagnosing food allergy has been a challenge. Read more about this study

About this study
Food allergy is on the rise within the pediatric population. Having food allergy can cause medical, nutritional and psychological issues in those who suffer with it. Although making the appropriate diagnosis of food allergy is very important, properly diagnosing food allergy has been a challenge. Skin prick testing and food-specific IgE testing of the blood can give positive results that are false. Currently, Oral Food Challenges are the best way to diagnose a food allergy. Unfortunately, Oral Food Challenges are time consuming and may not be readily available to suspected food allergy sufferers. This study is designed to examine the effectiveness of an allergy-detecting blood test called IMMULITE 2000 manufactured by the study sponsor, Siemens.

Questions about this trial
What is this clinical trial studying?
An observational study of Peanut Allergy and Milk Allergy, run by National Jewish Health at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Relationship between food specific IgEs (time frame: approximately 2 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2020; AzTrials last refreshed its copy on 8 Nov 2026.
