Discrepant cases showed values <0.16 kUA/L by ImmunoCAP assay for the following allergens and data are not described: e1, cat; e5, dog; m6, Alternaria alternata; i6, cockroach; t7, oak; f3, fish (cod); f4, wheat; wheat; f14, soybean; f13, peanut. Phadiatop assay values ≥0.35 PAU/L, AlloScreen values >100 IU/mL, and ImmunoCAP values ≥0.35 kUA/L are considered positive. N21 was not confirmed.

^*These are the results of Phadiatop Infant test. ^†This is a result of both Phadiatop test and Phadiatop Infant test. ^†Test for hx2 (house dust mixes) also showed negative results. ^§Positive result for D. pteronyssinus (I18). ^∥Positive result for D. farinae (I19). d1, D. pteronyssinus; d2, D. farinae; w1, ragweed; w6, mugwort; f1, egg white; f2, cow’s milk; f24, shrimp, ND; not done.
