Lymph node or Other Solid Tumor “Set Up and Hold” Archiving
In several instances, a call has been received by HematoLogics asking if cytogenetic analysis can still be performed on a lymph node or solid tumor that was not ordered initially with flow cytometry. If the sample is more than a few days old, this may not be an option due to decreasing tumor cell viability. For this reason, if material is available, HematoLogics cytogenetics laboratory will process the specimen and archive it. Cytogenetic analysis can be performed on the specimen, but do degrade over time. Follow-up cytogenetic orders are time sensitive and the window of opportunity is only a couple of weeks. However, FISH studies or molecular testing can be run outside that shorter time frame.
