Figure. ; Basophil activation test (BAT) results. Activated basophil counts for the negative control (2.8%), positive control (35.2%), flomoxef (2.2%), rocuronium (3.2%), and rubber dam sheet (54.7%) challenges. Stimulation of naïve basophils with the rubber dam sheet elicited a strong positive result (1-hour contact; sample concentration, 1/1250). Evaluation criteria for activated basophils were as follows: <6% negative, 6–10% false-positive, 10–15% weakly positive, 15–20% positive, and >20% strongly positive.
