How can I utilize the quantitative level of Phadiatop (0.35 – 100 PAU/l)?

Phadiatop is reported in a quantitative manner (atopy grading) and regarded positive if ≥0.35 PAU/l. The result reflects the degree of sensitization (adds up the sum of IgE antibodies) to common environmental allergens. Patients having Phadiatop results of e.g. 1 PAU/l and 75 PAU/l respectively, are most probably having totally different clinical presentation; the higher the level the higher probability of clinical symptoms. The Phadiatop level could also guide if you should keep looking (sum of Specific IgE at much lower level) or stop looking (sum of Specific IgE at similar level) for additional IgE provoking allergens.
