A method for testing for biological molecular indicators in urine. Urine is transported through a sample container under pressure to flow through the sample container so that antigens in the urine, are collected and bound on antibodies immobilized on the beads to form antigen-antibody complex. The beads are washed to remove cell debris and charged molecules and a specific prelabelled antibody solution is passed through the sample container with the prelabelled antibodies attaching to a receptor site on the captured antigen to form are antibody-antigen-prelabelled antibody sandwich complex. This sandwich complex is washed to remove cell debris and charged molecules and mixed with a color reagent solution which reacts with the prelabelled antibody to produce an color indicating the presence of a specific cancer antigen.
