Test & specimen information
FISH analysis (postnatal)
Overview
Interphase Fluorescent in situ Hybridisation or FISH, can provide rapid results for the detection of chromosomal trisomies like Down syndrome (trisomy 21). FISH may also be used for urgent microdeletion syndrome confirmation^ and to diagnose certain classes of paediatric cancers.
^this requires prior discussion with the laboratory.
FISH provides a rapid result in 24-48hrs but is followed up with a conventional karyotype or molecular karyotype depending on the clinical indication and FISH result.
