Environmental and workplace allergy testing information for providers

Testing helping inform preventative strategies for your patients

As a primary care physician, you can play an important role in first-line management of allergies. Help manage your patients’ allergic diseases—whether triggered by environmental or workplace allergens—with a detailed medical history, a physical examination and an investigation of IgE antibodies through a blood test.

Environmental allergies

Allergic responses can develop to previously tolerated substances, and sensitization to seasonal and/or perennial allergens in the environment often accumulate to trigger allergic symptoms. Your patients may display symptoms of rhinitis, but non-allergic rhinitis and allergic rhinitis have different management strategies, underscoring the importance of an accurate diagnosis.

Workplace allergies

Possible allergic diseases found in the workplace, which include rhinitis, conjunctivitis, asthma, hypersensitivity pneumonitis, contact urticaria and contact dermatitis, can result in long-term health impairment yet many occupational allergic diseases are largely underrecognized.1

Who to test for environmental, workplace or seasonal allergies

Consider testing for allergic rhinitis in patients with asthma, eczema (atopic dermatitis), conjunctivitis, sinusitis, polyposis, upper respiratory tract infections, otitis media and sleeping disorders, as well as in children with learning and attention impairments.

For patients with suspected workplace inhalation exposure to specific allergens or suspected contact urticaria or contact dermatitis, IgE blood testing can establish IgE-mediated sensitization to allergens encountered in the workplace.

Environmental and workplace allergy testing information for patients

Understand the source of your symptoms

If you’ve noticed one or more of the following symptoms:

  • Stuffy, itchy or runny nose
  • Sneezing
  • Watery, red, itchy eyes and/or swollen eyelids
  • Itchy throat
  • Swelling of mouth/airways

You may be experiencing an allergy, such as a:

  • Seasonal allergy from the pollens of grass, trees or weeds
  • Indoor allergy from mold, dust mites and/or animal dander
  • Workplace allergy from exposure to occupational chemicals, animals, mold, agricultural sources and/or a variety of materials

You may be sensitized to more than one allergen, meaning that your unwelcome symptoms may be caused by multiple allergens—such as dust mites, mold and grass pollen. If you are exposed to multiple allergens together, higher levels of exposure can add up and trigger your symptoms.

Get answers from your healthcare provider

Many different allergens—substances that cause an allergic reaction—can be found both inside and outside your home and even at your workplace.

To understand which allergens may be triggering your symptoms, the first step is to schedule an appointment with your healthcare provider and ask if blood-based allergen-specific IgE testing can help provide answers. This allergy test is:

  • A convenient blood test
  • Appropriate for anyone (age 3 months and older)
  • Not affected by prescription or over-the-counter medications

Along with a medical exam and discussion with your doctor, the results of a blood test can help your healthcare provider or specialist:

  • Control your allergy symptoms
  • Determine which allergens trigger your symptoms or condition
  • Determine how to best eliminate or reduce your allergy triggers
  • Prescribe medication
  • Refer to a specialist for additional testing, if needed
