Gary Falcetano, Scientific Affairs Manager for Allergy at Thermo Fisher Scientific, is a leader in allergy and autoimmune diagnostics, providing specific IgE tests and the instruments to run them. Accurately diagnosing allergies can be challenging, but specific IgE testing can help confirm the underlying causes by looking at individual allergen components for precise diagnosis. This is the first step in determining the appropriate management approach to potentially interrupt the atopic march, where allergies can progress or even be life-threatening.
Gary explains, "It runs the gamut of just about anything that could potentially be an allergy disease. So I think the majority of our testing is done in both environmental allergies and food allergies. What people think about when we, especially this time of year in the US, with spring about to become a big onslaught, are environmental allergies, including pollens, grass, trees, and weeds. Also, looking at some of the indoor triggers to environmental allergies like dust mites, pets, molds, and mice is pretty key when assessing for respiratory-type symptoms. On the food side, any of a number of foods can potentially cause a patient to produce specific IgE, which is the sensitization that allows us to become allergic."
"We all think of respiratory allergies as straightforward, but there's an overlap of symptoms, especially from non-allergic causes, that can cause similar symptoms. So when thinking about respiratory allergies, we think about nasal congestion, post-nasal drip, and cough. Those symptoms can all be certainly caused by allergies, but they also can be caused by non-allergic triggers. That's one of the places where diagnostic allergy testing or specific IgE testing comes in to confirm whether we're dealing with an allergy. Then, if it's an allergy, what specifically is driving the symptoms? Once we rule out allergy, we can go down a whole other diagnostic pathway for all the various causes, like non-allergic rhinitis."
