Sneezing, runny nose, congestion, itchy, watery eyes. It must be allergies, right?
There are two types of rhinitis: allergic and non-allergic. Up 87 percent of patients with allergic rhinitis have non-allergic rhinitis,5 and the treatment that works well for one type of rhinitis may be less effective for the other.15 Allergen-specific IgE testing may be helpful in confirming suspected symptom triggers or assessing ambiguous or complicated cases.
The allergens a person is exposed to can vary from one region of the country to another. That is why Labcorp offers regional respiratory profiles that includes allergens specific to different areas of the United States.
There are 20 different regional allergy profiles from which to choose, including specific geographic regions within numerous states. Labcorp testing utilizes Thermo Fisher ImmunoCAP® to analyze the most common allergic rhinitis triggers including pollens, mold, dust mites, furry animals and insect emanations.
Since the late 1990s, food allergy has become more common among children in the U.S.1 Children with a food allergy are also prone to developing other conditions such as asthma, eczema and respiratory allergies. 1 Collectively, these points make the diagnosis of food allergy an important concern in pediatric health today.
Labcorp’s quantitative allergen-specific IgE testing can be useful in assessing the potential that an atopic disposition might play in fostering chronic sinusitis or dermatitis and potentially asthma, thereby allowing the clinician to develop an optimal therapeutic approach at an early age.
When confronted with a suspected food allergy in a pediatric patient, there are several important considerations:
Clinical studies have shown that young children who develop atopic dermatitis12,13 or allergic rhinitis12,14,15 have an increased tendency to develop asthma as they grow older. The progressive development of increasingly debilitating disease as an atopic child grows into adulthood has been referred to by some researchers as the “allergy march.”13,14,15
Allergen component testing employs purified or recombinant allergens rather than allergen extracts. As a result, it can identify cross-reactive and specles-specific components. It can also differentiate components associated with mild/local reactions and those associated with severe/systemic reactions. Since most allergic individuals are sensitized to more than one allergen, component testing results may be particularly important in developing management strategies for these cases.5,7
Allergen component testing also adds the following to consider which may be important in respiratory symptom management.
