ABSTRACT:
By using a new pretreatment agent consisting essentially of a carboxylic acid-type cation exchange resin fiber or a siliconized glass fiber, the interfering components and the elements of turbidity present in a subject fluid for immunologic pregnancy test can be specifically removed without entailing a substantial loss of human chorionic gonadotropin contained in the subject fluid.
