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
Time of culture as well as testing, can vary depending on sample type and probes ordered.
This test must be ordered using a Cytogenetic test request form 43097 or through your ARUP interface. Please submit the Patient History Form - Chromosome Studies with the Electronic Packing List, available on ARUP's Web site, http://www.aruplab.com/home/consent_forms.jsp.
A processing fee will be charged if this procedure is canceled at the client's request, after the test has been set up, or if the sample integrity is inadequate to allow culture growth. The fee will vary based on sample type.
