Method and apparatus are provided for performing immunoassays employing a device comprising a relatively small test zone referred to as an immunosorbing zone, and a relatively large liquid absorbing zone in liquid receiving relationship with said immunosorbing zone. The immunosorbing zone includes a member of an immunological pair ("mip")--ligand and antiligand--bound to a support.

A signal producing system is employed in conjunction with said device having as one component a signal label bound to a mip. The signal producing system provides for production of a detectible signal in the immunosorbing zone in relation to the amount of analyte in a sample.
