IL-4 and IL-13 mRNA real-time PCR quantification on whole blood to assess allergic response

This study shows that whole blood real-time PCR is a valuable method for IL-4 and IL-13 mRNA measurement after in vitro allergen challenge. We suggest that it might be useful, complementing conventional markers, for the diagnosis and the follow-up of allergic diseases. Further assessments are required to evaluate the clinical potential of this technique.
