Description
A FISH (fluorescence in situ hybridization) assay for PDGFRB rearrangement is a laboratory test used to detect genetic changes within the PDGFRB gene, specifically rearrangements or translocations, which can be indicative of certain blood disorders. This test is often used as an aid in diagnosing and managing patients with suspected or confirmed myeloproliferative neoplasms (MPN) and acute lymphoblastic leukemia (ALL), especially those who might benefit from targeted therapies like tyrosine kinase inhibitors
