Results:
Patient 1.
Male, 55 years old, 2 years of therapy. Skin Prick tests positive for weeds, no positive results for food and vegetables. Immunology: tIgE=407,26 kU/l, sIgE for weeds in II class. Prick by Prick tests positive for apple and tomato. In the interview patient complaint about symptoms after eating apple and tomato.
