Limited role in the workup of myeloproliferative neoplasms in the setting of an otherwise optimal cytogenetic study. Aids in exclusion of cryptic BCR-ABL1 rearrangement in chronic myelogenous leukemia and in the exclusion of a PDGFRA abnormality in cases of neoplastic eosinophilia.

A processing fee will be charged if this procedure is canceled, at the client's request, after the test has been set up, or if the specimen integrity is inadequate to allow culture growth. The fee will vary based on specimen type.
Other specimen types may be acceptable, contact the Cytogenetics Laboratory for specific specimen collection and transportation instructions.
If cell pellets or dropped cytogenetics slides are not submitted, a processing fee will apply.
