Method:

Interphase Fluorescent in situ Hybridisation or FISH, is a technique use in the paediatric setting to 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. Interphase FISH is a useful technique because it uses uncultured cells, meaning it can provide rapid test turn around times (usually within 24-48 hours
