The invention provides a method for isolating or enriching a rare cell from a biological fluid of a mammal employing an antibody that binds a cell-surface antigen of the rare cell. The immobilized antibody is incubated with a sample of biological fluid that includes the rare cells and a plurality of other cells so as to form an antibody-rare cell complex. The complex can be detected or isolated and subsequently analyzed by any of a variety of physical, chemical and genetic techniques.
