89550
Useful For Suggests clinical disorders or settings where the test may be helpful
Diagnosis of familial SDHB, SDHC, or SDHD gene mutations or deletions in patients with paragangliomas or pheochromocytomas
Used in conjunction with phenotyping to tailor optimal tumor-surveillance strategies
Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
When this test is ordered, both SDH full gene analysis (amplification) and SDH gene sequencing will be performed. DNA extraction will always be performed at an additional charge. If SDH gene sequencing does not identify a mutation, then SDH deletion detection will be performed at an additional charge.
