Reference Intervals

BCL6 ,3q27 Breakapart Probe-Rearrangement:

In a normal cell, the expected signal pattern is two fused signals. In an abnormal cell with a rearrangement, the expected signal pattern is one red signal, one green signal, and one fused signal.

MYC, 8q24.21 Breakapart Probe-Rearrangement

In a normal cell, the expected signal pattern is two fused signals. In an abnormal cell with a rearrangement, the expected signal pattern is one red signal, one green signal, and one fused signal.

IGH, 14q32.3 Breakapart Probe-Rearrangement

In a normal cell, the expected signal pattern is two fused signals. In an abnormal cell with a rearrangement, the expected signal pattern is one red signal, one green signal, and one fused signal.

IGH::BCL2, t(14;18) Translocation Probe

In a normal cell, the expected signal pattern is two red signals and two green signals. In an abnormal cell containing a typical translocation, the expected signal pattern is one red signal, one green signal, and two fused signals.

MALT1, 18q21.3 Breakapart Probe-Rearrangement

In a normal cell, the expected signal pattern is two fused signals. In an abnormal cell with a rearrangement, the expected signal pattern is one red signal, one green signal, and one fused signal.

BCL1 (CCND1)::IGH, t(11;14) Translocation Probe

In a normal cell, the expected signal pattern is two red signals and two green signals. In an abnormal cell containing a typical translocation, the expected signal pattern is one red signal, one green signal, and two fused signals.

ALK (2p23) Breakapart Probe-Rearrangement

In a normal cell, the expected signal pattern is two fused signals. In an abnormal cell with a rearrangement, the expected signal pattern is one red signal, one green signal, and one fused signal.

MYC::IGH t(8;14) Translocation Probe

In a normal cell, the expected signal pattern is two red signals and two green signals. In an abnormal cell containing a typical translocation, the expected signal pattern is one red signal, one green signal, and two fused signals.

Testing Schedule
Routine, Monday - Friday no holidays
Disease Group
Cytogenetic Tests
Reflex Tests
FSKH, FSLH
What triggers the reflex testing
If MYC, BCL2, or BCL6 has a gene rearrangement, but the partner gene is not IGH, the case will be reflexed to IGK and IGL. This testing will be performed at an additional charge (CPT code 88377x2).
