Component Resolved Diagnostics (CRD) is a molecular food allergy test that measures IgE antibodies to specific food proteins. Unlike traditional allergy tests, CRD identifies exactly which protein component triggers a reaction, helping distinguish true allergies from cross-reactivity and predicting the risk of severe reactions more accurately. Key factors to consider before pursuing CRD testing include cost, availability, insurance coverage, and how results integrate into a broader clinical evaluation by an allergist. Below, you'll find detailed information on specific allergen components (such as peanut Ara h 2 or milk casein), clinical indications, benefits, limitations, and practical next steps. If you're experiencing symptoms that might point to a food allergy, don't guess — get clarity. Understanding your symptoms is the first step toward determining whether CRD testing or another evaluation is right for you.

Contact dermatitis is an inflammatory skin reaction that occurs when your skin barrier is damaged by irritants (such as harsh soaps or solvents) or allergens (such as nickel or certain plants), resulting in red, itchy, or painful patches. Identifying your personal triggers through a skin diary, patch testing, and temporary elimination is essential for preventing flare-ups and maintaining healthy skin. Key considerations include understanding your risk factors, applying prevention strategies, and knowing when to seek medical care. Because contact dermatitis symptoms can overlap with other skin conditions like eczema, psoriasis, or fungal infections, pinpointing the true cause can be difficult on your own.
