Blood test may predict allergy drop success

This study looked at whether two substances in the blood, sST2 and miR-223, can help doctors measure how active a dust mite allergy is and predict if a treatment called sublingual immunotherapy (allergy drops) will work. The study included 54 people with moderate-to-severe allergic rhinitis and 54 healthy volunteers. Participants with allergies received allergy drops for 6 months, and researchers measured their symptoms and blood markers to see if the markers could predict treatment success.
