Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

We recommend the following testing algorithm for patients with B-Cell Acute Lymphoblastic Leukemia (B-ALL):

-At diagnosis, conventional cytogenetic studies (BM / Chromosome Analysis, Hematologic Disorders, Bone Marrow) and a complete B-ALL FISH panel should be performed.

-At follow-up, conventional cytogenetic studies (BM / Chromosome Analysis, Hematologic Disorders, Bone Marrow) and targeted B-ALL FISH probes based on the abnormalities identified in the diagnostic study can be evaluated.

-If the patient clinically relapses, a conventional chromosome study is useful to identify cytogenetic changes in the neoplastic clone or the possible emergence of a new therapy-related myeloid clone.


The number of probes ordered will determine the price of the testing. 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.


Panel includes testing for the following abnormalities via the probes listed:

t(9;22), BCR/ABL1

t(12;21), ETV6/RUNX1

t(1;19), PBX1/TCF3

+4, +10, +17, Cen4/Cen10/Cen17

t(11q23;var), MLL

del(9p), CDKN2A/Cen9

t(14;var), IGH

17p-, TP53/Cen17


When an MLL rearrangement is identified, reflex testing is performed to identify the translocation partner. Probes include identification of t(4;11) AFF1/MLL, t(9;11) MLLT3/MLL, t(11;19)(q23;p13.1) MLL/ELL, and t(11;19)(q23;p13.3) MLL/MLLT1.


When an IGH rearrangement is identified, reflex testing is performed to using a CRLF2/IGH probes to identify a t(X;14)(p22.3;q32.33) and t(Y;14)(p11.32;q32.33)
