Referral patterns and evaluation of people with clonal hematopoiesis. People with clonal hematopoiesis may be identified in several different ways, including during testing for other conditions. Tasks for hematologists include helping affected persons understand clonal hematopoiesis and its implications, organizing further diagnostic testing that may be indicated in some cases (eg, bone marrow aspiration and biopsy), and developing a monitoring plan. Referral to other specialists may be necessary, including geneticists (eg, if a germline mutation is possible) or cardiovascular disease specialists for traditional risk factor assessment and modification.
