为定量测定变应原效力,曾采用多种方法包括按体积计算重量、花粉变应原单位、总氮量、蛋白氮单位和含量。但所得数据既不能直接测定变应原的效力,也与变应原的效力没有密切关系。用P-K试验效价和直接皮肤试验的终点作为变应原标准化的试验,会使病人感到不舒服。最近有人提出,采用组织胺释放和放射变应原吸附试验(RAS Various methods have been used to quantify allergenic potency, including weight by weight, pollen allergen units, total nitrogen, protein nitrogen units and contents. However, the data obtained neither directly measure the effectiveness of allergens, nor the effectiveness of allergens is not closely related. Patients who are not comfortable with standardized tests of allergen using the P-K test titer and the end point of a direct skin test. Recently, it has been suggested that the use of histamine release and radioactive allergen adsorption test (RAS
