1p/19q Co-deletion (Oligodendroglioma), paraffin
Use
FISH testing on paraffin-embedded cells is used for the detection of deletions of chromosome arms 1p and 19q. These deletions are frequent genetic abnormalities in primary human gliomas and are especially common in oligodendrogliomas. This provides important genetic information that can influence diagnosis and treatment planning.

Limitations
The analysis is not suitable for tissues preserved in B+ fixative or that have been decalcified. It requires proper fixation and sufficient tissue quantity to ensure reliable results. Extreme temperatures during shipment can affect the integrity of the specimen. Assay results may be impacted if minimum slide requirements are not met.
