Testing Algorithm
This test only includes a charge for professional interpretation of results and does not include charges for analysis.
Analysis charges will be incurred for total work performed, and generally include 2 banded karyograms and the analysis of 20 or more metaphase cells for this test. If no metaphase cells are available for analysis, no analysis charges will be incurred. If additional analysis work is required, additional charges may be incurred. See the Method Description for specific details.
The following algorithms are available:
-Acute Promyelocytic Leukemia: Guideline to Diagnosis and Follow-up
-Bone Marrow Staging for Known or Suspected Malignant Lymphoma Algorithm
-Multiple Myeloma: Laboratory Screening
-Myeloproliferative Neoplasm: A Diagnostic Approach to Bone Marrow Evaluation
