These studies involve culturing of living cells; therefore, turnaround times given represent average times, which are subject to multiple variables.
A processing fee will be charged if this procedure is canceled at the client's request after the test has been set up or if the specimen integrity is inadequate to allow culture growth.

Although bone marrow is the recommended specimen type for hematological disorder studies, blood can be substituted if bone marrow cannot be obtained. Refer to Chromosome Analysis, Leukemic Blood (ARUP test code 2002290). This test must be ordered using Oncology test request form #43099 or through your ARUP interface.
