Allergy Diagnosis? Alergy test is a common misspelling and variation of allergy diagnosis.
An allergy diagnosis is typically made through simple tests, such as a skin or blood test. Skin tests can determine if a person has IgE antibodies in the skin that react to a specific allergen. Although skin testing is the most sensitive and least costly way to diagnose allergies, people with skin conditions like eczema should not be tested using this method. In these cases, a blood test is the more appropriate way to make an allergy diagnosis.
