Pediatric Allergy Testing: At What Age Is It Worth It?

A total of 606 patients met inclusion criteria.

There were 31 patients who underwent allergy testing at <3 years and 575 patients who underwent allergy testing at ≥3 years.

Children age < 3 years demonstrated 15.1 (95% CI: 3.56-63.7) increased odds of negative allergy testing ( P < .001).

In the 295 patients with positive allergy testing, the odds of poly-sensitization (≥4 allergens positive) increased with age (OR: 1.09, 95% CI: 1.03-1.15, P = .004).
