The invention relates to a method for diagnosing a disease state mediated by pathogenic cells. The method comprises the steps of combining with an ex vivo patient sample a composition comprising a conjugate or complex of the general formula (I) Ab-X wherein the group Ab comprises a ligand that binds to the pathogenic cells and the group X comprises an imaging agent, and detecting the pathogenic cells that express a receptor for the ligand using flow cytometry. |
