OMB omalizumab, SPT skin prick test
aSeven serial 10-fold dilutions of fresh cow’s milk were prepared in sterile saline immediately before SPT. Each dilution (1:10, 1:102, 1:103, 1:104, 1:105, 1:106, 1:107) was placed at 4 cm intervals on the volar surface of both forearms. The mean weal diameter was calculated and the highest threshold of SPT was defined as follows: the highest dilution inducing a mean weal diameter of 3+ mm was considered the observed end-point dilution
