The Cytogenetics laboratory is service within the Sydney Genome Diagnostics (SGD) services based at The Children's Hospital at Westmead (CHW). We provide a NATA accredited service for the diagnosis of a wide range of constitutional (blood), prenatal and acquired (leukaemia, lymphoma and tumour) chromosome disorders.

We perform G-band karyotyping, fluorescence in-situ hybridsation (FISH), CGH and SNP Chromosome Microarray [CMA], quantitative fluorescent-PCR prenatal aneuploidy screening (QF – PCR) and RT-PCR testing (soft-tissue tumour biopsy specimens only).

These services are extended to all states and forms part of both the CHW Division of Laboratory Services and the Western Sydney Genetics Program.
