A method for detecting protein present on the surface of a sample is disclosed, wherein substances present on a portion of said surface are transferred to a sampling means and wherein, subsequently, these substances are contacted with a reagent capable of forming or changing color upon reaction with protein. Finally, the color changed or formed by this reaction is visually determined. In this method, the substances transferred onto the sampling means are also contacted with a specific type of nonionic or zwitterionic surfactant.
