This test uses fluorescence in situ hybridization (FISH) to detect molecular rearrangement of the BCR and ABL1 genes involved in translocation t(9;22). This translocation, resulting in an abnormally short chromosome 22 known as the Philadelphia chromosome (Ph), is associated with chronic myelogenous leukemia (CML), de novo acute myeloid ...

In CML, FISH can be used to look for specific pieces of the BCR-ABL gene on chromosomes. It can be used on regular blood or bone marrow samples without growing the cells first, so you get the results more quickly than with conventional cytogenetics.

Apr 3, 2025 · BCR-ABL for chronic myelogenous leukemia (CML), FISH; chromosome analysis; quantitative monitoring for CML by FISH; ABL deletions are confirmed by linked ASS analysis. Use This test is used to confirm the diagnosis of chronic myelogenous leukemia, establish the chronic-phase karyotype for comparison with blast crisis alterations and monitor ...

Fluorescence In Situ Hybridization (FISH). This laboratory test is used to examine genes and chromosomes in cells. It is a slightly more sensitive method for detecting CML than the standard cytogenetic tests used to identify the Ph chromosome.

Mar 31, 2025 · Fluorescence in situ hybridization (FISH) for myeloproliferative neoplasms/chronic myelogenous leukemia (MPN/CML) targeting numerical changes of chromosomes 8, 9, 13q14, and rearrangement of BCR/ABL1.

Fluorescence in situ hybridization (FISH) provides an important adjunct to conventional cytogenetics and molecular studies in the evaluation of chromosome abnormalities associated with hematologic malignancies.

This test uses fluorescence in situ hybridization (FISH) to detect molecular rearrangement of the BCR and ABL1 genes involved in translocation t(9;22). This translocation, resulting in an abnormally short chromosome 22 known as the Philadelphia chromosome (Ph), is associated with chronic myelogenous leukemia (CML), de novo acute myeloid ...

Fluorescence in situ hybridization (FISH) is used as a rapid and reliable molecular cytogenetic technique both in the diagnosis and subsequent monitoring of CML. On the other hand, FISH is applied to analyze both interphase and metaphase cells.

Despite the advent of molecular assessment, banding cytogenetics and fluorescence in situ hybridization (FISH) still have a significant role in diagnostic and prognostic approaches to chronic myeloid leukaemia (CML).
