Objective : The purpose of the study was to observe local reactions of BV and BVP skin test, and to compare those between BV and BVP. Methods : We performed BV or BVP Skin test to 42 patients, and then we measured wheal and erytherma on skin test area by digital caliper after 15 minutes. Results : 1. In BV Skin test, the mean size of wheals was $l0.l0{pm}0.78mm$ and the mean size of erythermas was $29.85{pm}6.23mm$. 2. In BVP Skin test, the mean size of wheals was $7.05{pm}3.20mm$ and the mean size of erythermas was $19.58{pm}7.62mm$. 3. The local reactions of BVP Skin test decreased significantly(P<0.01) than those of BV skin test.
