A minority of children reporting non‐immediate reactions to beta‐lactams (BLs) are allergic. Allergy workup usually includes late‐reading (48‐72 hours) skin tests (ST) and short (1‐3 days) drug provocation tests (DPT), regardless of the chronology of the index reaction. The sensitivity of hyper‐late‐reading (≥6‐7 days) ST and of prolonged DPT for the diagnosis of non‐immediate hypersensitivity to BLs is yet to be determined.
