Description
Natalia Rzetecka-Mańka and nine co-authors compare blood amino acids in young children with asthma and allergy in a 2026 study. The two conditions often arrive together, and in children under five the diagnosis leans on symptoms and trial and error because lung tests are hard at that age. A blood marker would help.
The team profiled free amino acids in 113 serum samples across four groups: asthma alone, allergy alone, both, and neither. Samples came from children aged six months to five years and were measured with a standardized kit on sensitive instruments. One amino acid, asparagine, stood out as differing between the groups. The rest of the profile was mapped for comparison. The authors present the difference as a candidate molecular clue for sorting these overlapping diagnoses earlier. Larger studies would need to confirm it before any clinical use.
