The Vysis CLL FISH Probe Kit is a test to detect deletion of the LSI TP53, LSI ATM, and LSI D13S319 probe targets and gain of the D12Z3 sequence probe target via fluorescence in situ hybridization (FISH) in peripheral blood specimens from patients with B-cell chronic lymphocytic leukemia (CLL) to aid in identifying those patients eligible for treatment with Venclexta® (venetoclax).
Vysis CLL FISH Probe Kit Contents
This kit contains five reagents sufficient to process 20 assays.
An assay is defined as one 22 mm x 22 mm Vysis LSI TP53 SpectrumOrange/ATM SpectrumGreen probe hybridization area and one 22 mm x 22 mm Vysis LSI D13S319 SpectrumOrange/13q34 SpectrumAqua/CEP 12 SpectrumGreen probe hybridization area.
Each kit includes:
The Vysis CLL FISH Probe Kit is a test to detect deletion of the LSI TP53, LSI ATM, and LSI D13S319 probe targets and gain of the D12Z3 sequence probe target via fluorescence in situ hybridization (FISH) in peripheral blood specimens from patients with B-cell chronic lymphocytic leukemia (CLL).
Indications For Use
In untreated patients, the assay may be used to dichotomize CLL (the 13q-, +12, or normal genotype group versus the 11q- or 17p- group) and may be used as an aid in determining disease prognosis in combination with additional biomarkers, morphology, and other clinical information. The test is indicated for detecting deletion of the LSI TP53 probe target (17p-) as an aid in identifying those patients with CLL for whom treatment with VENCLEXTA® (venetoclax) is indicated. Vysis CLL FISH Probe Kit is not intended for monitoring of residual disease.
The test is for prescription use only

Hybridization of Vysis LSI TP53 SpectrumOrange/ATM SpectrumGreen Probes is expected to produce two orange p53 and two green ATM signals in cells with two normal copies of chromosomes 17 and 11.
Hybridization of Vysis LSI D13S319 SpectrumOrange/13q34 SpectrumAqua/CEP 12 SpectrumGreen Probes is expected to produce two orange D13S319, two green CEP12, and two aqua LSI 13q34 signals in cells having two normal copies of chromosomes 12 and 13.
Gains or losses of a specific probe target sequence will be observed as cells with either greater than or less than, respectively, two signals for that probe.
While some abnormal CLL specimens are aberrant for only one probe locus, others may be abnormal for two or more loci. Other abnormal signal patterns may also occur.
