All patients in the food (n = 26) and venom group (n = 34) had a prescription for an AAI. In 3 of the 13 patients with unknown elicitor an AAI was not prescribed due to primary elicitor suspicion on drug and they did not complete the diagnostic work-up. These 3 were excluded from the table. Number of prescriptions for AAI is unknown for the drug group and this group is not included in the table (n = 50)
^aThere was a significant difference between grade 1-3 and 4-5 anaphylaxis and retrieval of AAI (p < 0.02)
^bThe table includes 5 of 8 mastocytosis patients. Of the 3 not included 2 had anaphylaxis elicited by drug. Both patients picked up an AAI. One of the 3 had no AAI prescribed due to death before the evaluation was completed
