The present invention relates to a multiparameter lateral flow strip (), comprising a microporous membrane layer () supported on a liquid-impermeable support layer (), for lateral flow of a liquid through the microporous membrane layer (), wherein the microporous membrane layer () has two or more flow lanes () in the direction of lateral flow, wherein said two or more flow lanes () are separated by hydrophobic separation channels (), and wherein each of said two or more flow lanes () comprises a detection spot () including a binding agent, wherein said two or more flow lanes () are isomorphic lanes. Furthermore, the present invention relates to a multiparameter lateral flow immunoassay device comprising said multiparameter lateral flow membrane (), the use of said multiparameter configured lateral flow membrane () in an immunological test, as well as to a method for the manufacture of said multiparameter configured lateral flow membrane ().
