Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This test includes a charge for application of the first probe set (2 FISH probes) and professional interpretation of results.


Additional charges will be incurred for all reflex probes performed. Analysis charges will be incurred based on the number of cells analyzed per probe set. If no cells are available for analysis, no analysis charges will be incurred.


This assay includes testing for the following abnormalities using the probes listed:

ABL2 (1q25) rearrangement

FIP1L1/CHIC2/PDGFRA (4q12) rearrangement (CHIC2 deletion)

PDGFRB (5q33) rearrangement

ABL1 (9q34) rearrangement


If an ABL1 rearrangement is identified, reflex testing will be performed using the BCR/ABL1 dual-color, double fusion FISH probe set to evaluate for the presence or absence of BCR/ABL1 fusion.


If the patient is being tracked for known abnormalities, indicate which probes should be used.
