Test ID: FBALL
B-Cell Acute Lymphoblastic Leukemia (ALL), FISH
Secondary ID
A test code used for billing and in test definitions created prior to November 2011
Useful For
Suggests clinical disorders or settings where the test may be helpful
As an adjunct to conventional chromosome studies in patients with acute lymphoblastic leukemia (ALL), especially:
-When conventional chromosome studies do not demonstrate a classic chromosome anomaly
-For pediatric patients
-When results for conventional chromosome studies are normal or unavailable because of an unsuccessful study
Detecting clones with t(1;19), t(9;22), t(12;21), t(11;var), t(14;var), del(9p), +4, +10, or +17
Quantifying disease before treatment and after therapy for patients with ALL
Assessing residual disease after treatment. In this situation, it is cost effective to order only those FISH probes that produced abnormal results prior to treatment.

Testing Algorithm
Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
This panel includes testing for the following anomalies via the probes listed. The entire panel is recommended for pediatric patients.
t(9;22), BCR/ABL
t(12;21), ETV6/RUNX
t(1;19), PBX/TCF3
+4, +10, +17, Cen4/Cen10/Cen17
t(11q23;var), MLL
del(9p), CDKN2A/Cen9
t(14;var), IGH
Pediatric patients: Please indicate if you would like the entire panel. This is suggested for pediatric patients with new diagnosis. If the patient is being tracked for known anomalies, please indicate which anomalies need to be investigated.
When an MLL rearrangement is identified, reflex testing is performed to identify the translocation partner. Probes include identification of t(4;11) AF4/MLL and t(11;19)(q23;p13.1) MLL/ELL.
Adult patients: Only FISH for BCR/ABL and MLL are recommended in adult patients with B-cell ALL.
When this test is ordered, a charge for 2 FISH probes and interpretation is included. If additional probes or the entire panel are ordered, additional probe charges will be added.
