Unit Code 89551:
Succinate Dehydrogenase (SDH) Subunit B Gene Analysis

Useful For Suggests clinical disorders or settings where the test may be helpful

Diagnosis of familial SDHB gene mutations or deletions in patients

with paragangliomas (PGLs) or pheochromocytomas (PCs)

 

Tailoring optimal tumor-surveillance strategies for patients, when

used in conjunction with phenotyping

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Unit Code. Profile information lists tests performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

 Unit Code  Reporting Name  Available Separately  Always Performed 
 31631  SDH Subunit B Gene Analysis No Yes
 89557  SDH Subunit B Gene Sequencing No Yes

Additional Tests Lists test(s) that are always performed, at an additional charge, with the initial test(s)

 Unit Code  Reporting Name  Available Separately  Always Performed 
 28640  DNA Extraction No Yes

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 subunit B gene analysis (amplification) and SDH subunit B gene sequencing will be performed. DNA extraction will always be performed at an additional charge.

Special Instructions and Forms Describes specimen collection and preparation information, test algorithms, and other information pertinent to test. Also includes pertinent information and consent forms to be used when requesting a particular test
