Diagnosing Allergies, Asthma, and Immunodeficiencies
At UPMC, the initial evaluation of people who are suspected to have allergies, asthma, or immunodeficiency, includes:
- A thorough physical examination
- An evaluation of past medical history
- A comprehensive assessment of symptoms
Allergy symptoms
Allergies can cause symptoms that involve your:
- Skin
- Sinuses
- Airways
- Digestive system
The severity of allergies varies from person to person and can range from minor irritations to potentially life-threatening emergencies.
Immunodeficiency can cause recurrent infections of the:
- Sinuses
- Lungs
- Other organ systems
The most prevalent adult immunodeficiency is common variable immunodeficiency, which can be treated with antibody infusions to boost the immune system to help fend off infections.
Testing for allergies, asthma, and immune deficiencies
To help make a diagnosis, UPMC specialists may order the following tests and procedures:
- Laboratory studies – to evaluate many allergic and immunologic diseases
- Allergy skin testing – to evaluate allergic symptoms to pollen, dust mites, molds, pets, bee stings, and foods
- Patch skin test – to check for allergic reactions to chemicals and metals
- Medication allergy testing – if skin testing is negative, our experts may give you the medication to rule out allergy
- Nasal endoscopy- to better evaluate chronic sinusitis versus allergies
- Pulmonary function tests – to assess the functional status of the lungs
- Exhaled nitric oxide – a new biomarker for asthma
- Methacholine challenge test – to rule out asthma
- Radiologic studies – to help differentiate asthma from sinus disease
- Flexible laryngoscopy – to evaluate for vocal cord dysfunction (spasms), which can often mimic asthma or cause cough or throat tightness
