Overview

The primary purpose of the 1p & 19q test is to identify co-deletion of chromosomes 1p and 19q in brain tumor cells, which is indicative of oligodendroglioma. This genetic information helps in confirming the diagnosis, predicting prognosis, and guiding treatment decisions, as oligodendrogliomas with this co-deletion often respond better to chemotherapy.
