Test Discontinuation

Advanced Technology Laboratory, Cytogenetics

Discontinuation of Low-Volume and Individual Fluorescence in situ Hybridization (FISH) Probes

Effective immediately, due to low test utilization and the high cost of maintaining proficiency, the following FISH tests will no longer be offered:

• Prader-Willi/Angelman (15q11-q13) by FISH

Recommended test is Angelman/Prader-Willi mPCR

Smith Magenis (17p11) by FISH

• Williams (7q11,23) by FISH

If need arises for this test, please place an order for a Send out Genetics Miscellaneous and enter requested test in the comments. The testing will be sent out through Spectrum Health.
