A patient has a hematologic malignancy. Karyotyping is performed for all of the following reasons except:
a. To provide unique cytogenetic profile to confirm the patient's identification
b. To provide diagnostic information
c. To identify whether the patient will respond to appropriate therapy
d. To provide prognostic information
ANS: A
Patients with various forms of cancers, including hematologic forms, may exhibit a nonrandom abnormal karyotype. This karyotype can provide useful diagnostic information, identify whether the patient will respond to appropriate therapy, and provide prognostic information for the patient. It does not confirm the patient's identification.
