Abstract
Abstract An apparatus for testing biological molecular indicators in urine comprising a tubular container, and a sample container holding beads with immobilized ligands. Urine is transported through the tubular container under pressure to flow through the sample container which screens off the antibodies so that antigens of the carried by the urine fluid are collected and concentrated on the beads.
