We report on two patients in whom results of skin tests to injectable bovine collagen (Zyderm) became positive six weeks after administration. In one of these patients, the test was repeated, and showed identical result. It is recommended that Zyderm skin test sites be observed for at least six weeks before the test result is considered negative.
我们报告了两名患者，他们在注射牛胶原蛋白（Zy derm）后六周，皮肤试验结果呈阳性。其中一名患者重复进行了该试验，结果相同。建议在认为皮肤试验结果为阴性之前，对Zy derm皮肤试验部位观察至少六周。
