The present invention is directed toward an apparatus and a method which can use immunoassay in sample treatment apparatus for diagnostic and testing purposes of urine by concentrating specific urine antigen in a small volume area and concentrating the urinary sediments in a separate small volume area. Urine is transported through the tubular container under pressure to flow through the sample container which screens off the urinary sediments and the beads so that antigens carried in the urine are collected and concentrated on the beads.
