Evaluation and Validation of Novel Diagnostic Tool for Allergists (AbioSCOPE)

Study Overview
=================
Brief Summary
-----------------
In this study, investigators evaluated for the first time the diagnostic efficacy of abioSCOPE® versus Phadia Laboratory System as an aid in the diagnosis of allergic diseases. Investigators targetted the agreement between test results obtained in abioSCOPE® and a laboratory reference method (Phadia Laboratory System, ThermoFisher Scientific, Uppsala, Sweden), considered as a quasi-gold standard in IgE (immunoglobulin E) antibody assays. Investigators also reported the medical decision taken by a panel of allergy experts who had access to patient history, skin tests and IgE antibody assay, but blinded to the method used, i,e, the reference method or the abioSCOPE® .

Eligibility Criteria
-----------------
Inclusion Criteria: Subjects examined at ambulatory medicine medicine center CHUV / PMU and for wich serum sample is required for the research of specific IgE (allergic patients, allergic group) or for any other reason (immunological) (non-allergic control patients, control group) Subjects for which it is expected (allergic group subjects) or who will be asked (non-allergic control group) to perform a panel of standard prick tests as basic allergological investigation, including pollen birch, grasses, mites (D pter, D far), cat dander. Obtain informed consent from each subject before any study procedure. Exclusion Criteria: Presence of positive HIV-1 viremia by the ultra-sensitive method in the 12 months preceding the study. Use of any investigational or non-registered product (drug or vaccine) Chronic administration (more than 14 days) of immunosuppressive or immunomodulatory drugs in the 6 months preceding the study for corticosteroids. This means a dose of Prednisone or equivalent substance greater than or equal to 0.5 mg per kg / day. Inhaled topical steroids are allowed. Administration of any immunoglobulin, any immunotherapy or administration of some blood products in the 3 months preceding the study, or planned during the study period. Any health condition or patient history, in the opinion of the investigator, could interfere with the evaluation of the study's objectives. Participation in another experimental protocol during the period of the study. Demonstration, confirmation or suspicion of a condition of immunosuppression or immunodeficiency (including HIV infection) based on medical history and physical examination (no laboratory test). A family history of congenital or hereditary immunodeficiency. Subjects taking any of the following medications: antihistamines in the week preceding the consultation, systemic steroids (inhaled or nasal steroids are allowed), anti-cytokines or cytokines, systemic interferon (injection local interferon α for the treatment of HPV is allowed) or treated with systemic chemotherapy.
