Am J Clin Pathol 2018;150:S84-S89 DOI: 10.1093/AJCP/AQY095 Conclusions: Of 727 bone marrow specimens received, 118 (16.2%) were cancelled subsequently after the clinician was emailed. The most common reasons for cancellation were normal bone marrow aspirate/biopsy report (67 of 118; 56.8%), wrong test ordered (25 of 118; 21.2%), duplicate orders (12 out of 118; 10.2%), and cytogenetic testing was previously done with normal results (10 out of 118; 8.5%). Cancellation of FISH testing when adequate conventional karyotype was obtained was recently instituted (6 out of 75; 8%). A focused intervention can help prevent overutilization of cytogenetic testing as well as encourage collaborative interactions between the pathologists and the oncologists in ensuring better service to the patients. Unnecessary financial burdens for the patient and time-consuming labor for the geneticist can be preempted. This could serve as a tool to help pathology residents learn effective test utilization strategies.
