Blood testing clarifies the inflammatory biology of atopic dermatitis. Eosinophils reflect allergic Th2 activity; CRP signals systemic acute-phase inflammation. At Superpower, we offer eosinophils and CRP testing for atopic dermatitis, with in-clinic and at-home options. Home testing is currently available in selected states. (See FAQs below for more info).
