Milk allergy diagnosis involves evaluating symptoms that appear after consuming dairy, reviewing medical history, and using tests that measure the body’s immune response to milk proteins.
Skin prick tests and blood tests are commonly used to identify sensitivity, while an oral food challenge serves as the most definitive method for confirming an allergy. During this challenge, small and increasing amounts of milk are given under medical supervision to monitor for reactions.
Diagnosis also helps distinguish a milk allergy from lactose intolerance, which does not involve the immune system. Understanding the diagnostic process allows for proper management, including avoidance strategies and guidance from an allergist.
