INTERPRETIVE DATA:
Related Tests: Chromosome Analysis, Blood Leukemic Study
Methods: Giemsa band (G-band) analysis at approximately the 400 band level; 2 or more karyotypes, analysis of 20 metaphase cells and count of 20 metaphase cells
Test Variables: This study involves culturing of living cells. Therefore, turnaround times given represent average times which are subject to multiple variables.
Indications for Use:
- To identify acquired chromosome abnormalities frequently associated with specific types of hematologic malignancy
- To evaluate patients with known acquired chromosome abnormalities for relapse
