Detecting ETV6/RUNX1 or TEL/AML or t(12;21), or amplification of RUNX1 (iAMP21), are recurring abnormalities in B-cell ALL.

This test can be ordered individually or as part of the B-ALL FISH Panel. See the panel test for more details.

Only one specimen tube is required to perform all ordered cytogenetics testing.

The more testing requested, the closer to the optimal volume requirements is required.
