The 1p19q Deletion by FISH and IDH1 R132H Point Mutation by Immunohistochemistry with Reflex to IDH1 and IDH2 Mutation Analysis, Exon 4 test is a preferred initial test for diagnosing oligodendrogliomas. It detects IDH1 or IDH2 mutations and the co-deletion of 1p/19q, both of which are critical for a definitive diagnosis of oligodendrogliomas.
