Cytogenetics Hematopathology

G-banded Chromosome Analysis

Conventional cytogenetic studies to detect chromosomal gains, losses and rearrangements such as inversions and translocations for a variety of neoplasms including hematological malignancies and solid tumors.

*City of Hope Cytogenetics Laboratory is a Children’s Oncology Group (COG)-approved lab for conventional cytogenetic and FISH analyses.

Fluorescence In Situ Hybridization (FISH) Panels

Molecular cytogenetic FISH assays to detect or confirm previous or applicable abnormalities for a variety of neoplasms. Available FISH probes and panels are listed below.

* Currently available to City of Hope patients only. Please contact lab outreach for non-City of Hope availability status.

*Most commonly known designations are used here to indicate each abnormality identified by the FISH probes.

Whole-Genome Oncology Microarray (SNP-Array) for Hematological Malignancies (CytoScan HD)*

The CytoScan HD microarray provides high resolution whole-genome interrogation of newly diagnosed or relapse neoplastic specimens, including genome-wide copy number and copy-neutral loss of heterozygosity (CN-LOH) analyses.
