Fluorescence in situ hybridisation (FISH)

Where FISH studies for specific microdeletion syndromes are required this must be indicated on the request form.


  • FISH studies for a rapid pre- or postnatal aneuploidy screen have now been superseded in our laboratory by multiplex-PCR technology.
  • Subtelomeric screens are now performed by array CGH as part of developmental delay investigations.
  • Common microdeletion syndrome testing is now performed by BOBs analysis.
