Abstract
AIMS: In the present study, the authors intend to demonstrate the advantages of molecular diagnosis in immunoallergology through the description of a clinical case.CASE DESCRIPTION: We present the case of a 9-year-old male, followed by pediatric immunoallergology with the diagnoses of moderate persistent asthma, persistent rhinitis, atopic eczema and food allergy with severe manifestations (several episodes of anaphylaxis). molecular profile of allergic sensitization contributed to better knowledge of the patient, therapeutic and even prognostic adequacy.CONCLUSIONS: The molecular allergy diagnostic tests, according to the analysis of the present case, allows the establishment and escalation in terms of severity of a more individualistic sensitization profile, which is especially important in the patient who is polysensitized and with reports of respiratory and food allergies.
