BAT Cow's Milk for the Replacement of the Food Challenge Test

Study Purpose

The prevalence of children suspected of a cow's milk allergy is 17% in the Netherlands. Cow's milk diagnosis is based on a food challenge test However, this food challenge test is expensive, time consuming, risky, with waiting lists of several months. This waiting time results in unnecessarily long-term use of expensive hypoallergenic milk formula Therefore, there is a great need to introduce a better and faster diagnostic test for cow's milk allergy diagnosis in standard care. The in vitro Basophil Activation Test (BAT) is cheap, quick (result < 1 day, no waiting list), safe for the child and is a reliable alternative for the food challenge test to diagnose an IgE-mediated allergy. A diagnostic work-up with the BAT is expected to achieve a relevant reduction in the number of expensive and risky food challenges and the prescription of hypoallergenic formula. The reduction in diagnostic delay will increase quality of life. Objective: Determination of the (cost)effectiveness of the replacement of the expensive, risky and time-consuming food challenge test by the Basophil Activation Test (BAT) for the diagnosis of an IgE-mediated cow's milk allergy in children.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages N/A - 12 Years

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Cow Milk Allergy
Arms & Interventions


: Children with suspected cow's milk allergy


Diagnostic Test: - Blood draw

The burden for child/parents in this study is low as it is limited to a single blood draw, which is already necessary for usual diagnostic care in about 70% of the children
