| Method: ||Fluorescence in situ Hybridization|
|Note: ||Fluorescence in situ hybridization (FISH) is performed for specific abnormalities as follows: Microdeletion syndromes (e.g., Prader-Willi, Angelman, DiGeorge, Williams), Marker chromosome identification,and subtelomeric screening|
Remarks: It is recommended that all FISH studies be done in conjunction with routine cytogenetic analysis. (Refer to appropriate Chromosome Analysis test for order instructions). If FISH only is requested, please include copy of previous cytogenetics report. If dropped cytogenetics slides or cell pellets are not submitted, a processing fee will apply.
|Processing Info: ||Desired FISH probe and pertinent clinical diagnosis required with test order. Testing will not be performed until probe and diagnosis are provided; absence of this information will delay turnaround time.|
This test is not orderable in Powerchart or Logician. Send the request on a Downtime or Manual Requisition.
