From: Case of a 6-year-old boy with anaphylaxis induced by erythritol with positive skin prick test and negative basophil activation test

Results of the basophil activation test of the patient. A whole blood sample of the patient was incubated with serially diluted concentrations of erythritol for 1 h. The expression of CD203c on CD3−/CD294+ basophils was analyzed using fluorescence-activated cell sorting. Among the patient’s basophils, the CD203c-expressing cells were not affected by erythritol. The CD203c-expressing cells comprised 3.2%, 2.2%, and 2.1% of the solutions with erythritol concentrations of 5, 0.5, and 0.05 mg/mL, respectively (positive control, 28.6%)
