Guidelines may promote over-diagnosis of cow’s milk allergy in infants

International guidelines developed to help doctors diagnose cow’s milk allergy may lead to over-diagnosis, according to University of Bristol-led research published in the journal Clinical and Experimental Allergy today [8 December]. The study found that three-quarters of infants have two or more symptoms at some point in the first year of life, which guidelines say may be caused by cow’s milk allergy, yet the condition only affects one in 100.
